Description

  The present invention relates to a gaming machine that is shifted to a special gaming mode which is a gaming mode advantageous to the player by a combination of symbols that is not disclosed to the player, thereby increasing the probability of shifting to the special gaming mode. By providing operation means for switching the game state between an insured game state having a game compensation means to compensate for and a non-insurance game state having no game compensation means, various player demands The present invention relates to a gaming machine that satisfies the above requirements and has high gaming properties.

Conventionally, in a gaming machine such as a slot machine or a card game machine, a game is started by inserting a gaming medium such as a medal into the gaming machine, and thereafter, based on a lottery result of an internal lottery performed inside the gaming machine. The game result is displayed (for example, a predetermined symbol is stopped and displayed on the winning line in the slot machine, and the type of the drawn card is displayed in the card game machine). A predetermined amount of game media is paid out based on the game result.
In such a gaming machine, a gaming result that is advantageous to the player with a predetermined probability set in advance (for example, winning a winning combination) is set. Does not generate a game result that is advantageous to the player by consuming a certain number of game media, but the balance of game media set in advance when a considerable number of games are consumed It is configured to converge to (for example, a payout rate of 80%). Accordingly, there are cases where a large number of game media are acquired even though almost no game media are consumed, or only a few game media can be acquired even though a large amount of game media is consumed.
In this regard, while gambling becomes more interesting and the game is more interesting, there are cases where the player loses his expectation for the game due to the lack of favorable results, and this tends to lead to separation from customers. there were.

Conventionally, various gaming machines that have solved such problems have been proposed. For example, in Japanese Patent Application Laid-Open No. 2003-111070, a means for detecting that a player has been changed is provided in a gaming machine, and the cumulative consumption of credits in each gaming machine is managed for each player. When the accumulated consumption amount of consumed credit reaches a predetermined upper limit, it is configured to return the game medium reserved in advance to the player, and the predetermined upper limit can be set by the player's operation By doing so, a gaming machine is described in which the player can play the game with more peace of mind.
JP-A-4-244178 also provides an insurance coin slot in addition to a normal game start coin slot, and when three insurance coins are inserted there, the insurance function is activated. There is a description of a gaming machine in which a player's loss is reduced by paying out a predetermined number of coins as insurance dividend coins when the number of coins inserted in the game reaches a specified number.
JP2003-1117070 (pages 10-17, FIGS. 7-13) JP-A-4-244178 (pages 3 to 5, FIG. 3)

However, in the gaming machine described in Patent Document 1 described above, a return system is automatically performed in which a part of medals inserted is held back and consumption credits are returned regardless of the player's intention. Here, when using the return system, while it is possible to receive a return, it is common to require more game media than usual to play the same number of games. Therefore, there are some players who wish to play without using such a return system, and are uniformly applied to players who play the game while ignoring such player's speculation. To do so would reduce the player's willingness to play.
Further, in the gaming machine described in Patent Document 2 described above, once an insurance coin is inserted, an insurance period having an insurance function of paying out insurance dividend coins to the player is started, and the insurance period ends. Until then, the insurance function will continue to function regardless of the player's will. However, depending on the game situation, it may be advantageous for the player not to use the insurance function. Even in such a situation, ignoring the player's speculation and applying it uniformly reduces the player's willingness to play. I was supposed to let you.
Furthermore, in a slot machine that plays a game by changing and stopping the display of symbols in the past, a bonus game generated by a combination of symbols disclosed to a normal player (for example, “7, 7, 7”) and In addition, a special bonus game (a so-called mystery bonus game) that occurs when a combination of predetermined symbols not disclosed to the player (for example, “Bell / BAR / Plum”) is stopped and displayed on the active winning line. There is. Then, it has been desired to provide a new game using such a mystery bonus game.
Further, in the so-called slot machine that plays a game by changing and stopping and displaying symbols among the above gaming machines, a combination of symbols disclosed to a normal player (for example, “7, 7, 7”). In addition to the bonus game that occurs, a special bonus game that occurs when a combination of predetermined symbols not disclosed to the player (for example, “Bell / BAR / Plum”) is stopped and displayed on the active winning line ( So-called mystery bonus game). Although the mystery bonus improves the player's expectation of the game and makes it possible to provide a game that does not bore the player, it has been desired to provide a new game using such a mystery bonus game.

  The present invention has been made to solve the above-described conventional problems, and a game is played in a special game mode that is generated based on a combination of predetermined symbols not disclosed to the player based on the player's operation.

Credits equivalent to the inserted bills are added.

  In addition, a coin payout exit 15 is formed at the lower portion of the cabinet 2, and a coin receiving portion 16 that receives coins paid out from the coin payout exit 15 is provided. Arranged inside the coin payout opening 15 is a coin detection unit 73 (described later) configured by a hopper 71 capable of discharging coins one by one and a sensor (see FIG. 6). The number of coins paid out from the payout exit 15 is detected. Further, instead of directly paying out coins, a receipt-like one describing the number (value) of coins may be discharged. At that time, the player can exchange the prize for a prize by bringing the discharged receipt to the counter of the game shop.

Next, the insurance gauge 11 displayed on the lower liquid crystal display 4 will be described with reference to FIG. FIG. 4 is a front view showing an insurance gauge displayed on the slot machine according to the first embodiment.
The insurance gauge 11 is a gauge that is displayed on the lower liquid crystal display 4 when the current gaming state is set to the insurance joining gaming state by the INSURE ON / OFF button 13, while the insurance gaming gauge 11 is set to the insurance joining gaming state. The number of lost credits of the player up to now and the number of lost credits necessary to further increase the combination of winning symbols of the mystery bonus game are displayed in a bar graph form.

Here, the number of lost credits is paid out from “the number of credits betted (consumed) by the player using the BET buttons 33 to 35” based on the game result of the normal game or bonus game ( The value obtained by subtracting “acquired number of credits”, that is, the number of credits lost by the player as a result of the game.
As shown in FIG. 4, the insurance gauge 11 includes a gauge portion 90 that indicates the number of credits lost using a gauge region 89 at a ratio to the upper limit value (2000 credits in the first embodiment), and a loss immediately below the gauge portion 90. The initial value display unit 91 indicating the initial value of the credit number “0”, the upper limit value display unit 92 displaying the upper limit value “2000”, and the current loss credit number at the upper right end of the gauge area 89 are specified. The loss amount display section 93 is displayed with numerical figures.

When the player places a bet based on the credits owned, the gauge area 89 expands toward the right side, and the number of credits consumed by the numbers in the loss amount display section 93 (for example, 5 effective winning lines, When a game is played with 3 bets per line, it is increased by a total of 16 credits plus 1 insurance premium. One game (here, one game is a bet operation based on the current possession credits, the symbols are changed and stopped, and various processes (bonus game processing and When the number of lost credits exceeds the upper limit of 2000 credits, the mystery bonus from the next game will be compensated when the number of lost credits exceeds the upper limit of 2000 credits. In the period until winning the game, the game shifts to a special game compensation mode for further increasing the winning symbol combination of the mystery bonus game (see S95 in FIG. 18). After the credits are paid out, the number of lost credits is “0” which is an initial value, and the gauge display is also 0.
On the other hand, when a predetermined number of credits are paid out by winning a winning combination as a result of the game, the gauge area 89 shrinks toward the left and the number on the loss amount display section 93 is paid out. Decreases by the number of credits issued. However, the number of lost credits displayed by the insurance gauge 11 is “0” as the minimum value, and when the number of lost credits is 0 or less, that is, “the player bets using the BET buttons 33 to 35, etc. If the “number of credits paid out (acquired) based on the game results of the base game or bonus game” is larger than the “number of credits consumed” (when the payout rate is 100% or more), the loss amount display section “0” is always displayed in 93, and the display of the gauge area 89 is also 0.

  Then, by referring to the insurance gauge 11 displayed in this manner, the player can know the number of credits lost to the present when the game state is set as the insurance-added game state, In addition, it is possible to know a guideline for the transition to the special game mode in which the combination of symbols won in the mystery bonus game is increased in order to compensate for the loss. Therefore, the player can play a game according to the current game situation.

Subsequently, on the basis of FIG. 5, in the case of a normal game and a bonus game (including a normal bonus game and a mystery bonus game), an example of a symbol that is variably displayed while scrolling on each variable display portion 21 to 25 of the lower liquid crystal display 4. Will be described. In FIG. 5, the symbol row indicated by the first reel band 111 is the symbol row variably displayed on the variable display unit 21, and the symbol column indicated by the second reel band 112 is the variable display portion 22. A row of symbols variably displayed, a row of symbols indicated by the third reel band 113 is a row of symbols variably displayed by the variable display section 23, and a row of symbols indicated by the fourth reel band 114 is variably displayed. The symbol row variably displayed in the portion 24 and the symbol row indicated by the fifth reel band 115 are symbol rows variably displayed in the variable display portion 25.
It should be noted that dot data for forming an image of the symbol row indicated by the first reel band 111 to the fifth reel band 115 is stored in the image ROM 82 (see FIG. 7).

  Here, the symbol rows shown in the first reel band 111 to the fifth reel belt 115 have different symbol arrays, and these symbol columns are “LOBSTER”, “SHARK”, 13 types of symbols “FISH”, “PUNK”, “OCTOPUS”, “CRAB”, “WORM”, “A”, “K”, “Q”, “J”, “WILD”, “SARDINE” It is configured in combination.

  In this regard, “LOBSTER” indicates a lobster symbol. In addition, “SHARK”, “FISH”, “PUNK”, “OCTOPUS”, “CRAB”, “WORM”, “SARDINE” are those of shark, fish, guitar, shark, moth, insect, moth Each design is shown. In addition, “A”, “K”, “Q”, “J”, and “WILD” indicate symbols of each alphabet.

“LOBSTER”, “SHARK”, “FISH”, “PUNK”, “OCTOPUS”, “CRAB”, “WORM”, “A”, “K”, “Q”, “J” When a predetermined number of stops are displayed from the left end along the 1st to 20th pay lines L1 to L20, a predetermined number of credits is added as credits owned by the player (see FIG. 9).
“SARDINE” is a so-called scatter symbol, and when two or more of the variable display portions 21 to 25 are stopped and displayed regardless of the effective winning line, a predetermined credit number is given to the player. It is added as owned credits (see FIG. 9). Further, as will be described later, “SARDINE” is also a normal bonus game transition symbol for shifting to a normal bonus game (a normal bonus game in which a combination of symbols is disclosed to the player). Regardless, if four or more of the variable display sections 21 to 25 are stopped and displayed, the game can be shifted to the normal bonus game.
“WILD” is a so-called wild symbol that can be used in place of symbols other than “SARDINE” (scatter symbol).

In the row of symbols indicated by the first reel band 111 to the fifth reel band 115, one of the PLAY 1 LINE button 37, the PLAY 5 LINE button 38, and the PLAY 20 LINE button 39 is pressed, and the game is started. Then, each variable display unit 21 to 25 is scroll-displayed from the upper direction to the lower direction, and after the predetermined time has elapsed, the three symbols are stopped and displayed on the respective variable display units.
Furthermore, various winning combinations (see FIG. 9) are set in advance based on a plurality of combinations of the respective symbols, and when the combination of symbols corresponding to the winning combination is stopped on the effective winning line, Accordingly, the payout is added to the credit. If four or more “SARDINE” are stopped and displayed at the same time regardless of the winning line, the game proceeds to the normal bonus game.

Next, a configuration related to the control system of the slot machine 1 will be described with reference to FIG. FIG. 6 is a block diagram schematically showing a control system of the slot machine.
In FIG. 6, the control system of the slot machine 1 is basically configured with a CPU 50 as a core, and a ROM 51 and a RAM 52 are connected to the CPU 50. The ROM 51 has a main processing program, a normal game processing program, a normal bonus game processing program, a mystery bonus game processing program, a symbol lottery table for drawing a stop display symbol, a winning combination based on a combination of symbols to be stopped, In addition, a payout table (see FIG. 9) for setting a payout credit based on the winning combination, various programs necessary for controlling the slot machine 1, a data table, and the like are stored. In addition, the RAM 52 stores the number of credits currently owned by the player, the number of credits lost by the player while being set in the insurance game state, the remaining number of normal bonus games and mystery bonus games (free games), and other CPU 50 It is a memory for temporarily storing various calculated data.

It is also possible to determine in which direction it is moving.

Next, each storage area provided in the RAM 52 will be described with reference to FIG. FIG. 8 is a schematic diagram showing each storage area provided in the RAM 52.
As shown in FIG. 8, the RAM 52 is provided with an owned credit number storage area 52A in which the number of credits currently owned by the player is stored. In addition, from the number of credits lost by the player while being set in the insurance-added gaming state, that is, “the number of credits that the player has bet (consumed) using the BET buttons 33 to 35”, etc. A loss credit number storage area 52B is provided in which the number of lost credits obtained by subtracting the “number of credits paid out (acquired) based on the game results of the bonus game (including the normal bonus game and the mystery bonus game)” is stored. . Further, the number of lost credits stored in the lost credit number storage area 52B is determined to the player by the insurance gauge 11 (see FIG. 4) described above when the slot machine 1 is currently set in the insured gaming state. Inform the value. Further, the RAM 52 is provided with a bonus game number storage area 52C for storing the remaining number of bonus games to be executed when the normal bonus game and the mystery bonus game (both are free games in the first embodiment) are transferred. Yes.

  Next, when the base game and bonus game (including the normal bonus game and the mystery bonus game) are played in the slot machine 1 using the five variable display portions 21 to 25 in the slot machine 1, each stop display area 211 is displayed. The symbol lottery table used when determining symbols to be stopped and displayed on 213, 221 to 223, 231 to 233, 241 to 243, and 251 to 253 (see FIG. 2) will be described.

  The symbol lottery table is a lottery table for lottering symbols that stop on the first effective pay line L1 including the second stop display areas 212, 222, 232, 242 and 252 based on the random number values sampled by the random number sampling circuit 56. It is. Then, by determining the symbols to be stopped in the second stop display areas 212, 222, 232, 242, and 252, the upper and lower first and third stop display areas 211, 213, 221, 223, 231, 233, 241 are determined. Symbols to be stopped and displayed at 243, 251 and 253 are also determined from the arrangement of symbols on the reel band (see FIG. 5). Specifically, the code No. determined based on the random number value. Code No. smaller by 1 than Is stopped and displayed in the first stop display areas 211, 221, 231, 241, 251 and the code No. Code No. 1 larger than Is stopped and displayed in the third stop display areas 213, 223, 233, 243, 253.

In the slot machine 1 according to the first embodiment, the symbols to be stopped and displayed on the effective pay line L1 are determined for each of the variable display units 21 to 25. The symbol lottery table includes code numbers “00” to “29” corresponding to the symbol columns displayed on the first reel strip 111 to the fifth reel strip 115 in FIG. Are assigned in order from the top. A random value corresponding to is set.
Then, the CPU 50 samples five random number values via the random number sampling circuit 56 so as to correspond to each of the variable display units 21 to 25 at the start of the game, and displays the second stop display for each of the variable display units 21 to 25. The symbols to be stopped in the areas 212, 222, 232, 242, 252 are determined (for example, when the sampled random number value is “9”, the code number “09” assigned to “09”) The symbol (fish) is stopped and displayed in the second stop display area).

  Next, the winning combination and the payout in the case of playing the base game and the bonus game (including the base bonus game and the mystery bonus game) using the five variable display portions 21 to 25 in the slot machine 1 will be described with reference to FIG. To do. FIG. 9 is a payout table showing winning combinations and payouts when a game is played using five variable display sections, and shows payouts when the bet number is “1”. Therefore, when the bet number is “1”, the payout value shown in FIG. 9 is added to the credit. When the bet number is “2” or more, the payout value shown in FIG. The credit multiplied by the number of bets is added to the credit.

  Here, the winning combination and the payout in the case of playing the base game will be described in detail. As shown in FIG. 9, in regard to the symbol “LOBSTER”, the effective display line in the variable display portions 21 to 22 When it is continuously stopped and displayed (in the case of “2K” appearing continuously from the left end), a payout of “10” is obtained. Further, when the variable display sections 21 to 23 are continuously stopped and displayed on the effective pay line (in the case of “3K” appearing continuously from the left end), a payout of “320” is obtained. In addition, when the variable display units 21 to 24 are continuously stopped and displayed on the effective pay line (in the case of “4K” that appears four consecutively from the left end), a payout of “2500” is obtained. In addition, when the variable display units 21 to 25 are continuously stopped and displayed on the effective winning line in the variable display units 21 to 25 (in the case of “5K” appearing continuously from the left end), “6000”. Get a dividend.

  As for the symbol “SHARK” (鮫), when it is continuously stopped and displayed on the effective pay line in the variable display portions 21 to 22 (in the case of “2K” appearing continuously from the left end). In addition, a dividend of “3” is obtained. In addition, when the variable display units 21 to 23 are continuously stopped and displayed on the effective pay line (in the case of “3K” that appears three consecutively from the left end), a payout of “25” is obtained. In addition, when the variable display units 21 to 24 are continuously stopped and displayed on the effective pay line (in the case of “4K” which appears four consecutively from the left end), a payout of “150” is obtained. Further, when the variable display units 21 to 25 are continuously stopped and displayed on the effective pay line (in the case of “5K” appearing continuously from the left end), a payout of “1000” is obtained.

  Similarly, “FISH” symbol (fish), “PUNK” symbol (person with guitar), “OCTOPUS” symbol (蛸), “CRAB” symbol (蟹), “WORM” symbol (insect) ), “A” symbol (English letter), “K” symbol (English letter), “Q” symbol (English letter), and “J” symbol (English letter) as shown in FIG. A dividend is set for

  When the payout based on these symbols is on a plurality of effective pay lines, the total value of all payouts is added to the credit.

  On the other hand, in the case of the “SARDIN” symbol (で), it is a scatter symbol. In the case of “2K” in which two variable appearance portions 21 to 25 appear (stop display) regardless of the effective pay line. A dividend of “2” is obtained, a dividend of “5” is obtained when “3K” appears (stop display), and a dividend of “10” is awarded when “4K” appears (stop display). In the case of “5K” that appears five (stop display), a payout of “125” is obtained.

  Only the payout according to the symbol “SARDIN” (鰯) is obtained by multiplying the payout value shown in FIG. 9 by the total bet number (the product of the bet number and the number of effective pay lines) to the credit. At this time, if there is a payout other than the symbol “SARDIN” (鰯), the payout is also added to the credit.

  In addition, the symbol (鰯) of “SARDIN” is also a trigger symbol for the transition to the normal bonus game, and when four or more appear at the same time (stop display) on the variable display portions 21 to 25 regardless of the effective winning line, While obtaining the above-mentioned payout, it is possible to shift to a normal bonus game.

  Next, a normal bonus game and a mystery bonus game that constitute a bonus game which is one of the game modes performed by the slot machine 1 according to the first embodiment will be described below.

First, the normal bonus game will be described. The normal bonus game is a bonus game that is started when the combination of symbols disclosed to the player is stopped and displayed on the effective winning line by the upper liquid crystal display 3 or the like during the normal game. In many cases, the game is generally advantageous to the player. Here, “disclosed to the player” means that the information is provided to the player as confirmed information. For example, the information is displayed on the panel or display of the gaming machine so that the player can recognize the information. From those who know the information stored in the gaming machine, such as the judgment logic of the judgment means of the gaming machine, based on legitimate authority (game machine developer, manufacturer, seller, etc.) This means that the player has been informed by a person who has obtained the permission (the owner, operator, etc. of the game arcade, game center, casino, etc. where the game machine is located).
Then, in the slot machine 1 according to the first embodiment, when shifting to the normal bonus game, the game is automatically played continuously for 15 to 25 games according to the lottery result at the time of shifting to the bonus game without betting credits or the like. (So-called free game).

  Further, the number of bets and the number of effective winning lines in the normal bonus game are those used when the normal bonus game is transferred. In addition, the winning combination and the payout in the normal bonus game are the same as those in the above-described normal game, but the symbol “SHARK” (鮫) is treated as the symbol “LOBSTER” and the “SARDIN” When four symbols (鰯) appear together (stop display), the number of remaining games of the current normal bonus game is added. Here, as shown in FIG. 9, the “LOBSTER” symbol (lobster) is set to have a higher payout in comparison with the “SHARK” symbol (鮫). There is a high possibility that a large amount of credits can be obtained without consuming credits.

  Next, the mystery bonus game will be described. The mystery bonus game is a bonus game that starts when a combination of symbols that is not disclosed to the player during the normal game is stopped and displayed on the effective pay line, and is a normal bonus game. In many cases, the game is advantageous to the player. Here, “not disclosed to the player” means that it is not provided as confirmed information to the player, contrary to the combination of the symbols of the normal bonus game, and the general player expects to lose. Depending on the combination of symbols, the bonus game is entered. Therefore, the player can have a sense of expectation that the game may be shifted to a bonus game even when a combination of symbols that is not any of the disclosed symbols is stopped and displayed, and the game is diversified. And never let the player get bored.

  In the slot machine 1 according to the first embodiment, the combination of symbols to be won by the mystery bonus game is different based on the current gaming state (insured gaming state or uninsured gaming state). FIG. 10A is an explanatory diagram showing combinations of mystery bonus game winning symbols in an uninsured gaming state, and FIG. 10B is an explanatory diagram showing combinations of mystery bonus game winning symbols in an insurance participating gaming state. (C) is an explanatory view showing a combination of mystery bonus game winning symbols in the special game compensation mode that shifts when the player's loss becomes a certain level or more in the insurance-added gaming state.

When the current gaming state of the slot machine 1 is an uninsured gaming state, there are three combinations of patterns A to C as shown in FIG.
Pattern A is a combination of symbols when “LOBSTER”, “FISH”, “CRAB”, and “SHARK” are stopped and displayed continuously on the effective pay line in the variable display portions 21 to 24.
Pattern B is a combination of symbols when “OCTOPUS”, “PUNK”, “WORM”, and “A” are stopped and displayed continuously on the effective pay line in the variable display portions 21 to 24.
Pattern C is a combination of symbols when “A”, “K”, “Q”, and “J” are stopped and displayed continuously on the effective pay line in the variable display portions 21 to 24.
Then, when any combination of the patterns shown in the patterns A to C is stopped and displayed on the effective pay line during the normal game, the game shifts to the mystery bonus game.

On the other hand, when the current gaming state of the slot machine 1 is the insurance-added gaming state, there are three combinations of patterns D to F as shown in FIG.
The pattern D is a combination of symbols when “LOBSTER”, “FISH”, and “CRAB” are stopped and displayed continuously on the effective pay line in the variable display portions 21 to 23.
The pattern E is a combination of symbols when “OCTOPUS”, “PUNK”, and “WORM” are stopped and displayed continuously on the effective pay line in the variable display portions 21 to 23.
The pattern F is a combination of symbols when “A”, “K”, and “Q” are stopped and displayed continuously on the effective pay line in the variable display portions 21 to 23.
Then, when any combination of symbols shown in the patterns D to F is stopped and displayed on the effective pay line during the normal game, the game shifts to the mystery bonus game.

Further, when the current gaming state of the slot machine 1 is the special game compensation mode, there are three combinations of patterns G to I as shown in FIG.
The pattern G is a combination of symbols when “LOBSTER” and “FISH” are stopped and displayed continuously on the effective pay line in the variable display portions 21 and 22.
The pattern H is a combination of symbols when “OCTOPUS” and “PUNK” are stopped and displayed in succession on the effective pay line in the variable display portions 21 and 22.
The pattern I is a combination of symbols when “A” and “K” are stopped and displayed continuously on the effective pay line in the variable display portions 21 and 22.
Then, when any combination of symbols shown in the patterns G to I is stopped and displayed on the effective pay line during the normal game, the game shifts to the mystery bonus game.

Here, the combination of symbols in which the mystery bonus game is generated in the insurance-added gaming state is the same as the combination of symbols that are stopped and displayed on the active winning line in the variable display portions 21 to 23 as compared to the non-insurance gaming state. In addition, the type of symbol that is stopped and displayed on the effective winning line in the variable display unit 24 is not specified.
Therefore, in the combination of symbols in which the mystery bonus game is generated when the gaming state is set as the insured gaming state, which kind of symbol is stopped and displayed on the variable display unit 24 as compared with the uninsured gaming state. And the number of combinations increases. That is, the probability of winning the mystery bonus game increases.

In addition, the combination of symbols in which the mystery bonus game is generated in the special game compensation mode that shifts when the player's loss becomes a certain level or more in the insurance game state is variable compared to the insurance game state. The combination of symbols that are stopped and displayed on the effective winning line in 21 to 22 is the same, and the type of symbols that are stopped and displayed on the effective winning line is not specified in the variable display unit 23.
Therefore, the combination of symbols in which the mystery bonus game is generated when the special game compensation mode is entered is established no matter what type of symbols are stopped and displayed on the variable display portion 23 as compared with the insurance-added gaming state. The number of combinations is further increased. That is, the probability of winning the mystery bonus game is further increased.

  In addition, the special game compensation mode that shifts when the player's loss becomes equal to or greater than a certain level (2000 credits or more in the first embodiment) in the insurance-added gaming state continues until the mystery bonus is shifted as will be described later. Is done. Therefore, the player's loss can be appropriately compensated.

  In the slot machine 1 according to the first embodiment, a mystery bonus game generated by a combination of symbols not disclosed to the player is a game having the same content as a normal bonus game generated by a combination of disclosed symbols. Yes, when the game shifts to the mystery bonus game, the game is automatically performed continuously for 15 to 25 games according to the lottery result at the time of the bonus game transfer without betting credits or the like. Further, the number of bets and the number of active winning lines in the mystery bonus game are the same as those at the time of transition to the mystery bonus game. Furthermore, the winning combination and the payout in the mystery bonus game are the same as those in the normal bonus game. The symbol “SHARK” (鮫) is treated as the symbol “LOBSTER” and the “SARDIN” When four symbols (鰯) appear together (stop display), the number of remaining games of the current mystery bonus game is added. Therefore, by shifting to the mystery bonus game, it is highly possible that the player can acquire a large amount of credits and the like without consuming credits.

Here, in the slot machine 1 according to the first embodiment, the mystery bonus game and the normal bonus game are games of the same content performed under the same conditions. The mystery bonus game may be made more advantageous to the player than the normal bonus game by changing the type or winning combination. Further, the normal bonus game may be made more advantageous to the player than the mystery bonus game. Furthermore, the bonus game is not limited to a so-called free game format game, and may be a selection-type bonus game that proceeds by selecting a displayed option.
In addition, the symbol combination to be won in the mystery bonus game may be a symbol combination that is not disclosed to the player, and the type and position of the symbol that is stopped and displayed on the active winning line as shown in FIG. 10 are specified. It does not have to be a combination. For example, it is possible to win when a predetermined number or more (for example, four or more) of a specific symbol (for example, “FISH”) is stopped and displayed regardless of the effective winning line. Alternatively, a winning combination may be made when a plurality of types of predetermined symbols (for example, “FISH”, “WORM”, and “CRAB”) are stopped and displayed on the effective pay line regardless of the stop position.

As described above, in the slot machine 1 according to the first embodiment, when the player uses the INSURE ON / OFF button 13 to set the insurance participation gaming state, the mystery bonus is paid as a price for paying the insurance premium when placing a bet. Since the combination of symbols to win the game is increased and the winning probability of the mystery bonus game is increased, it is possible to prevent the situation where the winning combination is not won even though the game is continued for a long time. Become.
Furthermore, when the loss amount of the player in the insurance-insured gaming state exceeds a predetermined amount, the winning probability of the mystery bonus game is further increased during the period until winning the mystery bonus game. It becomes possible to compensate appropriately.

  Next, a main processing program of the slot machine 1 according to the first embodiment having the above-described configuration will be described with reference to FIG. FIG. 11 is a flowchart of the main processing program in the slot machine according to the first embodiment. Each of the programs shown in the flowcharts in FIGS. 11 to 19 is stored in the ROM 51 and RAM 52 provided in the slot machine 1 and executed by the CPU 50.

  First, in step (hereinafter abbreviated as S) 1, a game state change acceptance process shown in FIG. 12, which will be described later, is performed. This process is a process of changing the current gaming state based on the operation of the INSURE ON / OFF button 13. In the slot machine 1 according to the first embodiment, there are two types of game states, an insurance participation gaming state having a loss compensation function and an uninsured gaming state which is a normal gaming state without a loss compensation function. The gaming state is switched by operating the ON / OFF button 13.

  Next, in S2, a start acceptance process of FIG. 13 described later is performed. This process is based on the operation of the BET 1 PER LINE button 33, the operation of the BET 3 PER LINE button 34, the operation of the BET 5 PER LINE button 35, the operation of the PLAY 1 LINE button 37, the operation of the PLAY 5 LINE button 38, and the operation of the PLAY 20 LINES button 39. In this process, the switch signals output from the 1-BET switch 57, the 3-BET switch 58, the 5-BET switch 59, the 1-LINE switch 60, the 5-LINES switch 61, and the 20-LINES switch 62 are received. Then, when the switch signal output from each switch is received, the game is started.

In S3, a lottery process shown in FIG. 14 described later is performed based on the switch signals output from the 1-LINE switch 60, 5-LINES switch 61, and 20-LINE switch 62 described above.
Here, when the bonus game is won (when four or more “SARDIN” symbols (鰯) are stopped and displayed simultaneously on the variable display portions 21 to 25 regardless of the effective pay line), this time. After the regular game is finished, a bonus game described later is performed (see FIG. 16). On the other hand, when the mystery bonus game is won (when the combination of symbols shown in FIGS. 10A to 10C is stopped and displayed on the effective pay line), the mystery described later is completed after the end of the current regular game. A bonus game is played (see FIG. 17).

  In S4, the normal game process of FIG. 15 described later is performed. Thereafter, the process proceeds to S5, and after the normal bonus game process shown in FIG. 16 described later is performed, the mystery bonus game process shown in FIG. 17 is performed (S6).

  Further, in S7, the loss compensation process of FIG. 18 is performed. In the loss compensation process, as will be described later, based on the number of player's lost credits, special game compensation that further increases the winning symbol combination until winning the mystery bonus game to compensate for the player's loss Enter mode. Thereafter, the main processing program ends.

  Next, the game state change acceptance process of S1 performed in the slot machine 1 will be described based on FIG. FIG. 12 is a flowchart of the gaming state change acceptance processing program according to the first embodiment. Here, the game state change acceptance process includes the current gaming state of the slot machine 1 based on the operation of the INSURE ON / OFF button 13, an insurance-added gaming state having a loss compensation function, and a loss compensation function. This is a process of switching between an uninsured gaming state that is not a normal gaming state.

  First, in S <b> 11, the CPU 50 determines whether or not the INSURE ON / OFF button 13 has been pressed based on a switch signal from the INSURE ON / OFF switch 76. When it is determined that the INSURE ON / OFF button 13 has not been pressed (S11: NO), the gaming state change acceptance process is terminated, and the process returns to the main process.

  On the other hand, if it is determined that the INSURE ON / OFF button 13 has been pressed (S11: YES), then the current gaming state of the slot machine 1 is set to either an insurance-insured gaming state or an uninsured gaming state. Is determined (S12).

If it is determined that the game state is not insured (S12: NO), the current game state of the slot machine 1 is changed to the insurance state and set (S13). In the slot machine that has been changed to the insurance game state, one credit is added and collected when betting credits owned using the BET buttons 33 to 35, etc. (S27). The winning symbol combination is increased (S14). Specifically, the combination of the mystery bonus game winning symbols is changed from the combination of the patterns A to C shown in FIG. 10A to the combination of the patterns D to F shown in FIG.
As a result, the winning determination is made based on the combination of symbols (combination of FIG. 10B) increased from the game played this time. Thereby, the probability of winning the mystery bonus game is increased, and by setting the insurance game state, the player can obtain a larger number of payouts than usual with the same bet number (the payout rate is increased). In addition, in the insurance game state, if the player's loss exceeds a certain level, as will be described later, the combination of winning symbols will be further increased during the period until winning the mystery bonus game to compensate for the player's loss. (S95) A loss compensation function is provided.

  Subsequently, in S15, the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is read. Here, the number of lost credits refers to “the number of credits betted (consumed) by the player using the BET buttons 33 to 35” while “insurance game state” is set, and the “normal game or bonus game” The number of credits minus the number of (acquired) credits paid out (acquired) based on the game results (including the normal bonus game and the mystery bonus game), that is, the player lost as a result of the game in the insured gaming state The number of credits.

  In S16, the insurance gauge 11 is displayed at a predetermined position on the lower liquid crystal display 4 based on the number of lost credits read in S15 (see FIG. 4). Thereby, the player can know that the current gaming state has been changed to the insurance-added gaming state and the amount of lost credits up to now. Thereafter, the process returns to the determination process of S11.

On the other hand, if it is determined in the determination process of S12 that the game state is an insurance-added game (S12: YES), the current game state of the slot machine 1 is changed to an uninsured game state (S17). In the slot machine 1 changed to the uninsured gaming state, the winning symbol combinations of the mystery bonus game are reduced (S18). Specifically, the combination of the mystery bonus game winning symbols is changed from the combination of the patterns D to F shown in FIG. 10B to the combination of the patterns A to C shown in FIG.
As a result, the winning determination is made based on the combination of symbols (combination of FIG. 10A) reduced from the game played this time, and the game is played based on the normal gaming state without the loss compensation function described later. Done.

  Subsequently, in S19, the insurance gauge 11 displayed at a predetermined position of the lower liquid crystal display 4 is erased (see FIG. 4). Thereby, the player can know that the current gaming state has been changed to an uninsured gaming state. Thereafter, the process returns to the determination process of S11.

  Next, the start acceptance process performed in S2 in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 13 is a flowchart of the start acceptance processing program in the slot machine according to the first embodiment.

  In the start acceptance process, first, in S21, the CPU 50 determines whether or not a predetermined time (for example, 15 seconds) has elapsed. If it is determined that the predetermined time has not elapsed (S21: NO), the process proceeds to S23 without doing anything, but if it is determined that the predetermined time has elapsed (S21: YES) ) In S22, after performing a demonstration effect on the upper liquid crystal display 3 and the lower liquid crystal display 4, the process proceeds to S23.

  In S23, based on the medal inserted from the coin insertion unit 9 or the banknote inserted from the bill insertion unit 10, a medal / banknote acceptance process for increasing the credits owned by the player is performed. Specifically, based on the detection of one medal by the coin sensor 49, the number of owned credits stored in the owned credit number storage area 52A of the RAM 52 is increased by one credit. Further, based on the detection of the banknote by the banknote sensor 67, the number of owned credits stored in the owned credit number storage area 52A of the RAM 52 is increased by the number of credits corresponding to the number of medals (for example, rented at 10 cents per medal). If there is, 10 credits will be increased by inserting 1 dollar bill). Further, the number of the owned credit number display unit 12 displayed on the lower liquid crystal display 4 is also updated accordingly.

In S24, it is determined whether or not an operation of the PLAY 1 LINE button 37, an operation of the PLAY 5 LINEs button 38, or an operation of the PLAY 20 LINEs button 39 has been performed. If it is determined that the PLAY 1 LINE button 37 or the like has not been operated (S24: NO), the process returns to S21 and the above-described processing is repeated, while the PLAY 1 LINE button 37 or the like is operated. If it is determined (S24: YES), the process proceeds to the determination process of S25 even during the demonstration effect.
In the determination process in S24, determination may be made not only with these operation signals but also with other input signals.

  In S <b> 25, it is determined whether the current gaming state of the slot machine 1 is set to an insured gaming state or an uninsured gaming state.

  If it is determined that the game state is not insured (S25: NO), the total number of bets (the product of the number of bets and the number of active winning lines, for example, BET5 PER LINE). Subtract the current player's credits based on the start of the button 35 and the PLAY 5 LINES button 38 with 5 active pay lines and 5 bets per line. (S26). Specifically, the number of owned credits stored in the owned credit number storage area 52A of the RAM 52 is read, the credits for the total bet number are subtracted, and the new credit number is written in the RAM 52 again. Accordingly, the number of the owned credit number display unit 12 displayed on the lower liquid crystal display 4 is also updated. Thereafter, the start acceptance process ends.

  On the other hand, if it is determined that the game is in the insurance participation game state (S25: YES), the number of credits obtained by adding one credit as an insurance premium to the number of credits corresponding to the total number of bets placed by the start acceptance process. (For example, using the BET5 PER LINE button 35 and the PLAY 5 LINES button 38 to start with 5 active pay lines and 5 bets per line will result in 26 credits) Subtract from owned credit (S27). Specifically, the number of owned credits stored in the owned credit number storage area 52 </ b> A of the RAM 52 is read out, the credit number added with the insurance premium is subtracted, and the new credit number is written into the RAM 52 again. As a result, one credit is collected as the insurance premium. Accordingly, the number of the owned credit number display unit 12 displayed on the lower liquid crystal display 4 is also updated.

  Thereafter, in S28, the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is read, and the total number of consumed credits obtained by adding one credit of the insurance premium to the number of credits bet in the current start acceptance process is added. Update its value.

  Further, in S29, the display of the insurance gauge 11 (see FIG. 4) is updated based on the number of lost credits updated in S28. Specifically, the gauge area 89 is enlarged in accordance with the ratio to the upper limit value of the number of credits added toward the right side (2000 credits in the first embodiment), and the number in the loss amount display section 93 is the current number. Increases by the number of credits consumed. Thereafter, the start acceptance process ends.

  Next, the lottery process performed in S3 in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 14 is a flowchart of a lottery processing program in the slot machine according to the first embodiment.

  In the lottery process, first, in S31, a symbol determination process is performed. Here, in the base game, the symbols to be stopped and displayed on the first pay line L1 are determined for each of the variable display portions 21 to 25. Specifically, as described above, the five random number values corresponding to each of the variable display units 21 to 25 are sampled by the random number sampling circuit 56, and the code number is read from the symbol lottery table. To decide. Furthermore, the code No. From the first reel band 111 to the fifth reel band 115, the symbols to be stopped and displayed are determined for each of the variable display portions 21 to 25.

When the symbols to be stopped and displayed on the effective winning line are determined, the lottery process is terminated after performing the combination determination process in S32. Specifically, in the combination determination process, based on the combination of the symbol determined in S31, the payout table in FIG. 9, and the mystery bonus winning symbol in FIG. 10 (A), (B) or (C), Winners and their dividends are determined.
At that time, if the current gaming state of the slot machine 1 is an uninsured gaming state, the mystery bonus game is based on the pattern combination of patterns A to C as shown in FIG. On the other hand, when the current gaming state of the slot machine 1 is the insurance-added gaming state, the decision is made based on the pattern combination of patterns D to F as shown in FIG. Is done. Further, when the current gaming state of the slot machine 1 is the special game compensation mode, it is determined based on a pattern combination of patterns G to I as shown in FIG.

  Next, the normal game process performed in S4 in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 15 is a flowchart of the base game processing program in the slot machine according to the first embodiment.

  In the normal game process, first, in S41, the variable is made based on the switch signals output from the 1-LINE switch 60, the 5-LINE switch 61, and the 20-LINE switch 62 received in the start reception process (S2). The symbols are scrolled on the display units 21 to 25.

  Thereafter, the scrolling of the symbols in the variable display sections 21 to 25 where the symbols are scrolling is stopped based on the symbol determination result of S31 (S42).

  Further, in S43, credits corresponding to the payout determined based on the payout table of FIG. 9 are paid out in accordance with the winning symbol combination stopped and displayed in the variable display sections 21 to 25 in S42. Specifically, the number of owned credits stored in the owned credit number storage area 52A of the RAM 52 is read, the credits paid out are added, and the new number of credits is written again. Accordingly, the number of the owned credit number display unit 12 displayed on the lower liquid crystal display 4 is also updated.

Next, in S44, it is determined whether the current gaming state of the slot machine 1 is set to the insurance participation gaming state or the uninsured gaming state.
And when it determines with it being an insurance non-insurance game state (S44: NO), the said normal game process is complete | finished in the state.

  On the other hand, if it is determined that the state is an insurance-added game state (S44: YES), the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is read, and the number of credits paid out in the present payout process The value is updated by subtracting the minutes (S45).

  In S46, the display of the insurance gauge 11 (see FIG. 4) is updated based on the number of lost credits updated in S45. Specifically, the area corresponding to the ratio to the upper limit value (2000 credits in the first embodiment) of the number of credits subtracted from the gauge area 89 toward the left side is reduced, and the number in the loss amount display unit 93 is Decreases by the number of credits earned. Thereafter, the normal game process ends.

  Next, the normal bonus game process performed in S5 in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 16 is a flowchart of the normal bonus game processing program in the slot machine according to the first embodiment.

In the normal bonus game process, first, in S51, it is determined whether or not the normal bonus game is won. Specifically, in the lottery process of S3, it is determined that four or more “SARDIN” symbols (鰯) are stopped and displayed on the variable display portions 21 to 25 regardless of the effective pay line. In this case, since the winning of the normal bonus game is made (S51: YES), the process proceeds to S52.
On the other hand, in the lottery process of S3, when four or more “SARDIN” symbols (鰯) are not stopped and displayed on the variable display portions 21 to 25 regardless of the effective pay line, the normal bonus game is entered. Is not won (S51: NO), and the normal bonus game processing program is terminated.

  In S52, the number N of normal bonus games is set. The number of normal bonus games is selected by lottery from 10 to 25 games based on the random number sampled by the random number sampling circuit 56. The set number N of normal bonus games is stored in the bonus game number storage area 52C of the RAM 52.

  Subsequently, in S53, symbol determination processing in the normal bonus game is performed. Here, in the normal bonus game, the symbols to be stopped and displayed on the first pay line L1 are determined for each of the variable display portions 21 to 25. Specifically, as described above, five random number values are sampled by the random number sampling circuit 56 so as to correspond to each of the variable display portions 21 to 25, and the code numbers are extracted from the symbol lottery table. To decide. Furthermore, the code No. From the first reel band 111 to the fifth reel band 115, the symbols to be stopped and displayed are determined for each of the variable display portions 21 to 25.

  When the symbols to be stopped and displayed on the valid pay line are determined, in S54, the winning combination and the payout thereof are determined based on the symbols determined in S53 and the payout table of FIG. However, in the normal bonus game, the symbol “SHARK” (鮫) is treated as the symbol “LOBSTER”.

  Further, in the combination determination process of S54, the winning combination (“SARDIN” symbol (鰯) is displayed at the same time on the variable display portions 21 to 25 regardless of the effective winning line) in the trigger combination to shift to the normal bonus game. It is determined whether or not the display has been stopped (S55). If the winning combination of the normal bonus game is won (S55: YES), the normal bonus game repeat count n is newly determined by lottery, and the determined repeat count n is determined by the current normal bonus game. Is added to the remaining game number N (S56). Thereby, if the normal bonus game is won during the normal bonus game, the remaining number of the normal bonus game is increased. More specifically, for example, when the game is first transferred to 20 bonus games, if the bonus game is won for the 17th bonus game at the 12th time, then 25 times (20-12 times + 17) Times) bonus game. On the other hand, if the winning combination of the normal bonus game is not won (S55: NO), the process proceeds to S57.

In the symbol variation process of S57, the symbols are automatically scrolled by the variable display portions 21 to 25.
Further, in the stop control process of S58, the scrolling of the symbols in the variable display sections 21 to 25 where the symbols are scrolling is stopped.

  Further, in the payout process of S59, the payout table of FIG. 9 (however, the symbol (SHARK) in the normal bonus game (in the normal bonus game) (in accordance with the symbol combination of the winning combination stopped and displayed in each variable display unit 21 to 25 in S58). Ii) is treated as a symbol (LOBSTER) of “LOBSTER”) and credits corresponding to the payout determined based on the payout are paid out.

Next, in S60, it is determined whether the current gaming state of the slot machine 1 is set to the insurance-added gaming state or the uninsured gaming state.
And when it determines with it being a non-insurance game state (S60: NO), it transfers to S63.

  On the other hand, if it is determined that the state is an insurance-added game state (S60: YES), the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is read, and the number of credits paid out in the present payout process Is updated by subtracting (S61).

  In S62, the display of the insurance gauge 11 is updated based on the number of lost credits updated in S61. Specifically, the area corresponding to the ratio to the upper limit value (2000 credits in the first embodiment) of the number of credits subtracted from the gauge area 89 toward the left side is reduced, and the number in the loss amount display unit 93 is Decreases by the number of credits earned. Thereafter, the process proceeds to S63.

  Thereafter, in S63, the CPU 50 reads the number N of remaining games of the normal bonus game stored in the bonus game number storage area 52C of the RAM 52, and subtracts “1” from the value of the read number N of games. Then, the subtracted game number N is stored in the RAM 52 again.

  Next, in S64, the CPU 50 determines whether or not the number N of normal bonus games has reached the number determined in S52. Specifically, it is determined whether or not the number of games N stored in the RAM 52 has become “0”. If the number of games N is not “0”, that is, the number of times of execution of the normal bonus game is determined in S52. When it is determined that the number of times has not been reached (S64: NO), the process returns to S53 and the above-described processing is repeated. On the other hand, when the game number N is “0”, that is, when it is determined that the number of times determined in S52 has been reached (S64: YES), the normal bonus game processing program is terminated.

  Next, the mystery bonus game process performed in S6 in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 17 is a flowchart of the mystery bonus game processing program in the slot machine according to the first embodiment.

  In the mystery bonus game process, first, in S71, it is determined whether or not a mystery bonus game is won. Specifically, in the lottery process of S3, the winning symbol combination of the mystery bonus game on the active winning line (FIG. 10A in the uninsured game state, FIG. 10B in the insured game state, special) If it is determined that the combination shown in FIG. 10C is stopped in the game compensation mode, the mystery bonus game is won (S71: YES), and the process proceeds to S72.

  On the other hand, if none of the winning symbol combinations of the mystery bonus game is stopped and displayed on the active winning line in the lottery process of S3, the mystery bonus game is not won (S71: NO), and the mystery bonus game is selected. Terminate the processing program.

  In S72, the number T of mystery bonus games is set. The various processes of S73 to S84 performed below are the same processes as the normal bonus game, and the description thereof is omitted.

In the slot machine 1 according to the first embodiment, like the normal bonus game, the mystery bonus game is a free game that is played by automatically rotating a predetermined number of times without betting credits. It may be a selection-type bonus game that proceeds by selecting an option displayed on the screen.
In addition, during the normal bonus game, the winning symbol combination of the mystery bonus game on the effective winning line (FIG. 10A in the uninsured game state, FIG. 10B in the insured game state, and in the special game supplement mode) When the combination shown in FIG. 10C is stopped and displayed, it is possible to control to shift to the mystery bonus game even during the normal bonus game.

  Next, the loss compensation process performed in S7 in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 18 is a flowchart of the loss compensation processing program in the slot machine according to the first embodiment.

In the loss compensation process according to the first embodiment, first, in S91, it is determined whether the current gaming state of the slot machine 1 is set to an insurance participation gaming state or an uninsured gaming state.
And when it determines with it being a non-insurance game state (S91: NO), the said loss compensation process is complete | finished in the state.

  On the other hand, if it is determined that the state is an insurance-added game state (S91: YES), it is subsequently determined whether or not the current slot machine 1 is in the special game compensation mode (S92). Here, in the slot machine 1 according to the first embodiment, as described above, when the number of credits lost in the insurance participation gaming state reaches a certain level or more, the loss until the winning of the mystery bonus game is lost. In order to compensate for this, the mode is shifted to the special game compensation mode. In S92, it is determined whether or not the mode is already shifted to the special game compensation mode.

  If the slot machine 1 is not currently in the special game compensation mode (S92: NO), the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is read (S93).

Further, in S94, it is determined whether or not the number of lost credits read in S93 exceeds the upper limit of 2000 credits, and if it is determined that the number of lost credits is less than 2000 credits (S94: NO). Ends the loss compensation process.
On the other hand, when it is determined that the number of lost credits is 2000 credits or more (S94: YES), the mode shifts to the special game compensation mode to compensate for the player's loss (S95). When the special game compensation mode is entered, the winning symbol combination of the mystery bonus game is further increased from the normal game insurance participation game state. Specifically, the combination of the mystery bonus game winning symbols is changed from the combination of the patterns D to F shown in FIG. 10B to the combination of the patterns G to I shown in FIG.
As a result, the winning determination is made based on the symbol combination (combination in FIG. 10C) further increased since the next game. Therefore, by shifting to the special game compensation mode, the probability that the player wins the mystery bonus game increases.

  Thereafter, the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is initialized to “0” (S96). In S97, the display of the insurance gauge 11 is updated based on the number of lost credits initialized in S96. Specifically, the number on the loss amount display section 93 is set to “0”, and the area of the gauge area 89 is set to 0 (see FIG. 4). Thereafter, the loss compensation process is terminated.

On the other hand, if the slot machine 1 is currently in the special game compensation mode (S92: YES), it is subsequently determined whether or not the special game compensation mode end condition is satisfied (S98). In the slot machine 1 according to the first embodiment, as described above, the case where the mystery bonus game is won in the current game is set as the termination condition of the special game compensation mode. Therefore, since the special game compensation mode in which the combination of winning symbols of the mystery bonus game is increased until the mystery bonus game is won, the player's loss can be compensated appropriately.
Note that the termination condition of the special game compensation mode is not limited to the above condition. For example, when the payout rate exceeds a predetermined value (for example, 90%), when a predetermined time or the number of games has elapsed since the start of the special game compensation mode, a predetermined number of credits are paid out from the start of the special game compensation mode. It is also possible to make it a condition if received.

  If the CPU 50 determines that the termination condition is satisfied (S98: YES), the special game compensation mode is terminated (S99). When the special game compensation mode ends, the winning symbol combination of the mystery bonus game is returned to the normal gaming insurance participation gaming state combination. Specifically, the combination of the mystery bonus game winning symbols is changed from the combination of the patterns G to I shown in FIG. 10C to the combination of the patterns D to F shown in FIG. Thereafter, the process proceeds to S93.

  On the other hand, when it is determined that the termination condition is not satisfied (S98: NO), the special game compensation mode is continued and the loss compensation processing is terminated.

  Next, an interrupt processing program executed in the slot machine 1 according to the first embodiment will be described with reference to FIG. FIG. 19 is a flowchart of the interrupt processing program in the slot machine according to the first embodiment.

  This interrupt processing program is executed at regular time intervals, for example, every 4 ms, while the processing of the main processing program is being performed, and the pressing of the COLLECT button 31 is monitored and the COLLECT button 31 is pressed. At that time, the number of credits stored in the RAM 52 is initialized.

  In this interrupt processing program, first, in S101, the CPU 50 determines whether or not the COLLECT button 31 has been pressed based on a switch signal from the COLLECT switch 45. If it is determined that the COLLECT button 31 has not been pressed (S101: NO), the interrupt process is terminated.

  On the other hand, when it is determined that the COLLECT button 31 has been pressed (S101: YES), it is subsequently determined whether or not the current slot machine 1 is playing (S102). Here, during the game of the slot machine 1, the operation of the BET 1 PER LINE button 33, the operation of the BET 3 PER LINE button 34, the operation of the BET 5 PER LINE button 35, the operation of the PLAY 1 LINE button 37, the operation of the PLAY 5 LINE button 38, Switches output from the 1-BET switch 57, the 3-BET switch 58, the 5-BET switch 59, the 1-LINE switch 60, the 5-LINES switch 61, and the 20-LINES switch 62 based on the operation of the PLAY 20 LINE button 39 This refers to the period from when a signal is received until the loss compensation process (S7) is completed.

  When the slot machine 1 is playing a game (S102: YES), even when a switch signal is received from the COLLECT switch 45, the interrupt process is terminated in that state.

  On the other hand, when the slot machine 1 is not playing (S102: NO), medals corresponding to the number of credits stored in the owned credit number storage area 52A of the RAM 52 (one medal per credit in the first embodiment). Is paid out (S103).

Thereafter, in S104, each credit number stored in the owned credit number storage area 52A and the lost credit number storage area 52B of the RAM 52 is initialized (the credit number is set to “0”). Thereby, when the next player plays, there is no remaining game data including data on the loss compensation function of the previous player.
Therefore, with regard to the loss compensation function that is performed especially in the insurance game state, for example, when a player plays a game without winning a prize for a while and then moves to another game machine, immediately after moving There is no risk that other players sitting in the game will receive an increase in the winning probability (S95) of the mystery bonus game due to the loss compensation process on the gaming machine. In addition, when a player wins a role in succession, receives a lot of credits, and then moves to another gaming machine, the other player who sits immediately after moving will have more than 2000 credits. Even when credit is lost, there is no possibility that a trouble such as an increase in the winning probability (S95) of the mystery bonus game due to the loss compensation process cannot be received. As a result, one player can properly compensate for the loss of the player whether he / she continues the game on the gaming machine that has been played first or moves to another gaming machine. It becomes possible, and the player can play the game with peace of mind.

As described above, in the slot machine 1 according to the first embodiment, by operating the INSURE ON / OFF button 13, the current gaming state of the slot machine 1 is changed from the insurance joining gaming state having the loss compensation function to the loss Since it is possible to switch between an uninsured game state which is a normal game state without a compensation function (S13, S17), the player can press the INSURE ON / OFF button 13 to press the loss compensation function ( When betting credits owned using the BET buttons 33 to 35, etc., 1 credit is added as an insurance fee and collected (S27). In addition, the combination of symbols won in the mystery bonus game is increased (S14). If the player's loss exceeds a certain level, the player will win the mystery bonus game. It is possible to appropriately select whether or not to use the function of compensating for the loss of the player by further increasing the combination of symbols (S95) based on the current situation, The convenience of the player is improved. In addition, it is possible to provide a gaming machine having high gaming properties that satisfies various player demands.
Here, since the mystery bonus game is generated by a combination of symbols that is not disclosed to the player, the game shifts to a bonus game that gives advantageous conditions to the player by a combination of symbols that a general player expects to lose. It will be. Therefore, the player can have a sense of expectation that the game may be shifted to a mystery bonus game even when a combination of symbols that is not disclosed is stopped. And never get bored of the player.
Further, when the insurance game state is set by operating the INSURE ON / OFF button 13, the insurance gauge 11 (see FIG. 4) is displayed on the lower liquid crystal display 4 (S16), and the player is displayed. By referring to the insurance gauge 11, it is possible to determine the transition to the insurance game state, the number of credits that have been lost in the insurance game state until now, and the guideline until the mystery bonus game is forcibly elected. It becomes possible to know. Therefore, the player can play a game according to the current game situation. If the non-insured gaming state is set, the display of the insurance gauge 11 (see FIG. 4) is erased from the lower liquid crystal display 4 (S19), so that the player has transitioned to the uninsured gaming state. Since the display unnecessary for the player is eliminated, it is possible to concentrate the game.
Further, when the COLLECT button 31 is pressed, the number of lost credits is initialized (S104), so that, for example, a player plays a game without winning a prize for a while, and then the other gaming machine When moving, there is no possibility that another player who sits immediately after moving receives a rise in the winning probability (S95) of the mystery bonus game due to the loss compensation process on the gaming machine. In addition, when a player wins a role in succession, receives a lot of credits, and then moves to another gaming machine, the other player who sits immediately after moving will have more than 2000 credits. Even when credit is lost, there is no possibility that a problem such as an increase in the winning probability (S95) of the mystery bonus game due to the loss compensation process will not occur. As a result, one player can properly compensate for the loss of the player whether he / she continues the game on the gaming machine that has been played first or moves to another gaming machine. It becomes possible, and the player can play the game with peace of mind.

However, as a means for collecting the insurance premium when set in the insurance participation gaming state, the insurance premium is obtained by adding and consuming one credit when the slot machine 1 according to the first embodiment makes a bet. The slot machine according to the second embodiment is different from the slot machine 1 according to the first embodiment in that it is collected by reducing the credits to be converted at the stage of inserting medals from the normal, whereas the slot machine according to the second embodiment is collected (S27). Yes.

  First, in the slot machine according to the second embodiment, a start acceptance process performed in S2 of the main process program will be described with reference to FIG. FIG. 20 is a flowchart of the start acceptance processing program of the slot machine according to the second embodiment. 20 and 21 are stored in the ROM 51 and RAM 52 provided in the slot machine according to the second embodiment, and are executed by the CPU 50.

  In the start acceptance process, first, in S151, the CPU 50 determines whether or not a predetermined time (for example, 15 seconds) has elapsed. If it is determined that the predetermined time has not elapsed (S151: NO), the process proceeds to S153 without doing anything, but if it is determined that the predetermined time has elapsed (S151: YES) ) In S152, after performing a demonstration effect on the upper liquid crystal display 3 and the lower liquid crystal display 4, the process proceeds to S153.

  In S153, based on the medal inserted from the coin insertion unit 9 or the banknote inserted from the bill insertion unit 10, a medal / banknote acceptance process for increasing the credits owned by the player is performed. Here, in the slot machine according to the second embodiment, when a medal or bill inserted in the state of being set in the insurance participation gaming state is received, a credit corresponding to a predetermined ratio (3% in the second embodiment) is given. Collected as insurance premiums. The medal / banknote acceptance process will be described in detail later.

In S154, it is determined whether or not an operation of the PLAY 1 LINE button 37, an operation of the PLAY 5 LINE button 38, or an operation of the PLAY 20 LINES button 39 has been performed. If it is determined that the PLAY 1 LINE button 37 or the like has not been operated (S154: NO), the process returns to S151 and the above processing is repeated, while the PLAY 1 LINE button 37 or the like is operated. If it is determined (S154: YES), the process proceeds to S155 even during the demonstration effect.
Note that in the determination process of S154, determination may be made using not only those operation signals but also other input signals.

  In S155, the total number of bets (the product of the number of bets and the number of active winning lines, for example, the BET5 PER LINE button 35 and the PLAY 5 LINEs button 38 are used to set 5 effective winning lines, The current player's owned credit is subtracted based on the number of bets per line when starting with 5 bets (S155). Specifically, the number of owned credits stored in the owned credit number storage area 52A of the RAM 52 is read, the credits for the total bet number are subtracted, and the new credit number is written in the RAM 52 again. Accordingly, the number of the owned credit number display unit 12 displayed on the lower liquid crystal display 4 is also updated.

  Next, in S156, it is determined whether the current gaming state of the slot machine is set to an insured gaming state or an uninsured gaming state. And when it determines with it being in an insurance non-insurance game state (S156: NO), the said start reception process is complete | finished.

  On the other hand, if it is determined that the game is in the insurance participation game state (S156: YES), the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is read, and the number of credits betted in the current start acceptance process And the value is updated (S157).

  Further, in S158, the display of the insurance gauge 11 (see FIG. 4) is updated based on the number of lost credits updated in S157. Specifically, the gauge area 89 is enlarged in accordance with the ratio to the upper limit value of the number of credits added toward the right side (2000 credits in the first embodiment), and the number in the loss amount display section 93 is the current number. Increases by the number of credits consumed. Thereafter, the start acceptance process ends.

  Next, the medal / banknote acceptance process performed in S153 in the slot machine according to the second embodiment will be described with reference to FIG. FIG. 21 is a flowchart of a medal / banknote acceptance processing program of the slot machine according to the second embodiment.

In the lottery process, first, in S201, it is determined whether the current gaming state of the slot machine is set to an insured gaming state or an uninsured gaming state.
And when it determines with it being a non-insurance game state (S201: NO), it transfers to S202.

  In S202, the mystery bonus lottery table 102 (see FIG. 24) for the uninsured gaming state is selected as the mystery bonus lottery table used when determining whether or not to win the mystery bonus game.

  On the other hand, when it is determined that the state is an insurance-added game state (S201: YES), the number of lost credits stored in the lost credit number storage area 52B of the RAM 52 is subsequently read (S203).

  Further, in S204, it is determined whether or not the number of lost credits read out in S203 exceeds the upper limit of 2000 credits, and if it is determined that the number of lost credits is less than 2000 credits (S204: NO). Selects a mystery bonus lottery table 103 (see FIG. 25) for an insured gaming state as a mystery bonus lottery table used when determining whether or not to win the mystery bonus game (S205).

  If it is determined that the number of lost credits is 2000 credits or more (S204: YES), the special game compensation mode is entered to compensate for the player's loss (S206), and the mystery bonus game is won. The mystery bonus lottery table 104 (see FIG. 26) for the special game compensation mode is selected as the mystery bonus lottery table used when determining whether or not (S207).

  In S208, a winning combination and a mystery bonus lottery process is performed. Here, in the normal game, the winning combination of the symbols to be stopped by the variable display units 21 to 25 is performed by the CPU 50 based on the normal combination lottery table 101 (see FIG. 23). Further, a lottery process for determining whether or not to win the mystery bonus game using the mystery bonus lottery tables 102, 103, and 104 (see FIGS. 24, 25, and 26) selected in S202, S205, or S207 is performed. Done. When the winning combination is determined, the process returns to the main process program and proceeds to the normal game process of S4. In the normal game process, the symbols are controlled to stop based on the determined winning combination. Further, when the mystery bonus game is won, a mystery bonus game process is performed thereafter.

  Here, based on FIGS. 24 to 26, a mystery bonus lottery table 102 for a non-insurance gaming state used for drawing a mystery bonus game in an uninsured gaming state, and an insurance used in an insurance joining gaming state. The mystery bonus lottery table 103 for the enrollment game state and the mystery bonus lottery table 104 for the special game supplement mode in the insurance participation game state will be described. FIG. 24 is a diagram showing a mystery bonus lottery table for an uninsured gaming state according to the third embodiment. FIG. 25 is a diagram showing a mystery bonus lottery table for an insurance gaming state according to the third embodiment. FIG. 26 shows a mystery bonus lottery table for the special game compensation mode according to the third embodiment.

  As shown in FIG. 24, the range of random values used in the mystery bonus lottery table 102 for an uninsured gaming state is 0 to 49, and the random values sampled through the random number sampling circuit 56 are 0 to 1. If there is, win the mystery bonus game trigger. In this case, the mystery bonus game is won regardless of the lottery result based on the normal combination lottery table 101. On the other hand, if the random number sampled through the random number sampling circuit 56 is 2 to 49, the game is lost and the mystery bonus game is not won.

  On the other hand, as shown in FIG. 25, the range of random numbers used in the mystery bonus lottery table 103 for the insurance participation gaming state is similarly 0 to 49, but the random values sampled through the random number sampling circuit 56 are If it is 0-3, it will win the mystery bonus game trigger. On the other hand, when the random number value sampled through the random number sampling circuit 56 is 4 to 49, it is lost.

  Furthermore, as shown in FIG. 26, the range of random values used in the mystery bonus lottery table 104 for the special game compensation mode is similarly 0 to 49, but the random number values sampled via the random number sampling circuit 56 If is 0-9, the player will win the mystery bonus game trigger. On the other hand, when the random number value sampled through the random number sampling circuit 56 is 10 to 49, it is lost.

  Here, the probability of winning the mystery bonus trigger is 2/50 in the uninsured gaming state, 4/50 in the insured gaming state, and 10/50 in the special game compensation mode. is there. Therefore, the probability of winning the mystery bonus game is higher in the insurance game state than in the non-insurance game state, and by setting the insurance game state, the player has the same number of bets and more than usual. Dividends can be obtained (payout rate increases). In addition, in the special game compensation mode, the probability of winning the mystery bonus game is higher than in the insurance-added game state, and by shifting to the special game compensation mode, the number of players with the same bet number is larger than usual. (You can get a higher payout rate).
