Definitions

  • the present invention relates to a symbol combination gaming machine such as a slot machine and a pachinko gaming machine comprising variable display means for variably displaying various symbols and a function to control the variable display to provide a player with a benefit based on the result.
  • a slot machine can be cited as a typical example of this kind of gaming machine.
  • the slot machine has a plurality of rotating reels, each of which has a plurality of symbols provided on a periphery thereof.
  • the slot machine is configured such that a predetermined amount of coins or award is paid out if a combination of symbols coincide with a predetermined combination, for example, if the same kind of symbols are lined up along a straight line such that the combination is one of the winning combinations when the rotating reels are stopped.
  • various kinds of contingencies are often involved to win the game.
  • the gaming machine has gambling characteristics or is characterized by such contingencies that a player may not be able to totally control his game results with his skills.
  • This pachi-slot gaming machine comprises random number sampling means, which samples a random number based on a start lever operation by the player, and a winning probability table, which is divided into the respective random number ranges of "big hit,” “mid hit,” and “small hit” in accordance with the ranks of winning combinations, and when a sampled random number falls within a winning region of the winning probability table, the gaming machine determines that the corresponding winning combination is won and sets the hit (winning) flag of this winning combination.
  • These winning flags include the winning flag of the winning combination called the "small winning combination,” which is generated when matching predetermined symbols (e.g., the "bell” or “cherry” symbol) line up along an activated pay line and by which about ten coins are paid out, and the winning flag of the winning combination called a “winning combination for a bonus game,” which is generated when matching predetermined symbols (e.g., "7" or "BAR” symbol) line up and by which a state, wherein a winning is more easily generated than normal gaming states, is entered for a predetermined number of times of gaming and the payout of about 100 to 400 coins can be received.
  • predetermined symbols e.g., the "bell” or "cherry” symbol
  • the state that the winning flag is established is the one called "internal winning” in general.
  • a related winning combination is just allowed to be lined up along the pay line and no winning is generated actually.
  • rotating winning symbols will be controlled with a timing to stop them along a pay line (normally, within four frames). This operation may be called “observation push.”
  • observation push refers to carrying out the stopping operation by carefully observing each of the reels so as to get desirable symbols along a pay line. If this operation timing is bad, the winning is not generated though the internal winning is generated. This state is called “missed winning.”
  • This missed winning may be called failing observation push on the whole and its causes may include several patterns.
  • a first pattern though the symbol to be aimed at is determined, a player fails to stop the reels as he aimed because he cannot recognize the varying symbols.
  • a second pattern a plurality of winning combinations are internally won in the current game but the player fails to stop the reels so as to win because he cannot decide which symbol to be aimed at in performing the stopping operation.
  • the player can improve accuracy to some degree by becoming skilled in the observation push technique.
  • the player must ascertain the internal winning state, which cannot be seen from the outside, and improvement of the accuracy of observation push is not possible no matter how skilled the player is in the observation push.
  • the stop control of the function is arranged such that no winning is generated, even if buttons are so pressed at the timing by the observation push that the reel should stop on the activated pay line, unless a stop operation is carried out in the order of the stop operation specified in the stop table.
  • the function of Super Time (ST) realizes a large number of coins comparable to the bonus game as "AT function" mentioned above by assigning an "notified" state of the type of the stop table selected and an "unnotified" state of that to the selected stop table.
  • the six kinds of operation orders of "left stop, middle stop, right stop,” “left stop, right stop, middle stop,” “right stop, left stop, middle stop,” “middle stop, right stop, left stop,” and “middle stop, left stop, right stop” are prepared and arrangements are made so that winning is not generated unless operation is performed exactly according to the operation order in the stop table selected by the random number lottery.
  • Notification effects include those that notify that a winning combination or the above-described AT gaming or ST gaming state has been won internally and those that notify that a state, in which the lottery winning probability of such a special gaming state is high, has been entered, and the notifications are made to the player by means of modes of blinking of lamps provided at the left and right sides of a panel display, images displayed on a liquid crystal display device, etc.
  • the order in which reels are to be stopped is notified by back lamps provided in the interior of the respective reels, lamps provided in correspondence to the respective reels, or a liquid crystal display device, dot display device, or other image display unit, an audio output generated from a speaker, etc.
  • back lamps provided in the interior of the respective reels, lamps provided in correspondence to the respective reels, or a liquid crystal display device, dot display device, or other image display unit, an audio output generated from a speaker, etc.
  • the stopping order is notified by use of back lights
  • the back light of the reel to be stopped is turned on and the other back lights of the other reels are turned off to indicate the reel (stop button) that is to be subject to a stopping operation.
  • An object of the present invention is to provide a gaming machine, with which a large amount of coins are paid out by indication of an operation method that is advantageous to the player, wherein the contents of the indication are notified to the player clearly and the player may play the game comfortably.
  • the means for notifying stopping order is an image display unit or lamp, etc.
  • the reel stopping operation since a player needs to perform the reel stopping operation upon checking the indication contents displayed by the image display unit or lamp and cannot avoid performing a sight line movement from "display device” to "reel", fatigue may be increased by playing in the Super Time (ST) gaming state.
  • the notified contents may not be heard well due to game sound generated by gaming machines in the surroundings, for example, when the bonus game is occurring at an adjacent gaming machine.
  • An object of the present invention is to provide a gaming machine, which is rich in gaming effects and which at winning performs highlighted display of the corresponding winning symbols to effectively notify to the player which winning symbols are aligned along which pay line.
  • a gaming machine has thus been proposed with which, when a player performs an erroneous stopping operation, an image expressing the occurrence of missed winning is displayed on a liquid crystal display device or a sound that differs from the normal reel stopping sound is emitted from a speaker to notify and bring attention to the player that an erroneous operation has been performed.
  • An object of the present invention is to provide a gaming machine, which, during the special gaming state, pays out a large amount of coins by indicating an operation method that is advantageous to the player and effectively notifies to the player whether or not an appropriate stopping operation has been performed to enable the player to play the special gaming state without fail.

  • the present embodiment is described with the ST period as an advantageous status for the player that is established by achieving the present object, the above-mentioned AT period may be applied instead or as an advantageous status for the player.
  • the winning flag of a specific winning combination may be established or the internal winning probability of a winning combination may be increased.
  • this invention may be applied in a similar manner to a pachinko gaming machine or an arcade gaming machine equipped with an electrical display device or to a home video game that executes the above-described functions in a simulating manner with a software.
  • an effect which is displayed with the electronic shutter being in the transmissive state, enables the reel symbols at the back side to be visually recognizable at parts at which the effect is not displayed, an effect mode in which reel symbols are mixed with an image effect can be expressed. Also, with an effect displayed with the electronic shutter in the shielding state, since an extraneous background will not be visible and the electronic shutter serves the role of a reflecting plate as well, an even clearer image effect can be expressed.
  • the present invention since it becomes possible to leave just the display regions that are to be displayed to a player in a highlighted manner and shield the other display regions in accordance with stop button operations of the player, information that match changes in the gaming situation can be transmitted effectively without being influenced by the installation positions of the display devices, the brightness of lamps, etc. Also, it becomes possible, in performing stopping operations during ST gaming, to play the ST gaming without movement of the line of sight from the image display unit, on which the stopping order is displayed, to the reels and since the control is carried out in accordance with the stopping operations of a player, the degree of fatigue of the player will be reduced. Also, the switching between the transmissive and shielding states can be performed instantaneously and since the shielded region can be controlled by software, finer effect control is enabled.
  • the electronic shutter is activated in the state in which all reels are stopped and since the electronic shutter can thus be controlled to be in the shielding state across the entire display panel without considering the hindering of observation push, which can be a problem in electronic shutter control during rotation of the reels, the execution of large and clear image effects is enabled.
  • the reel symbols besides the winning symbols are hidden by an electronic shutter and only the winning combinations are put in visually recognizable states, it is clear at a glance which winning combinations have become established along which pay line, the winning effect can thus be notified effectively to the player, and the game is made more interesting.
  • the winning symbols and the pay line can be notified to the player effectively even during ST gaming, in which the attention of the player is directed just to the stopping order and the concentration regarding which symbols are displayed in stopped form tends to be interrupted.
  • an erroneous stopping has been performed during ST gaming can be notified to a player without fail and without the player having to move his/her line of sight to other display devices. Also, since the performing of an erroneous stopping operation is notified not only by means of the control state of the shielding means but also by display of a predetermined image on the effect display part, more definite information transmission is enabled.
