2. Next, the method of this embodiment will be described with reference to the drawings.

  The game system of the present embodiment is configured to execute a battle game (an example of a game in which a player character appears) in which a player character battles an enemy character via a puzzle game.

  3, 4, and 6 to 9 are diagrams illustrating an example of a game screen (game image) generated by the game system of the present embodiment. The game screen GI is displayed on the display unit 190 (touch panel) of the terminal 10, and the player can perform an operation input by performing an operation (touch operation) for bringing a fingertip, a touch pen, or the like into contact with the touch panel.

  A game screen GI shown in FIG. 3 is an example of a game screen for the player to set a deck (game medium group). The game screen GI shown in FIG. 3 displays a predetermined number of game media GM constituting the current player's deck. The example shown in FIG. 3 indicates that four game media “A” to “D” among the game media owned by the player are set as the player's deck. When the player performs an operation of selecting a game medium GM to be changed on the game screen GI shown in FIG. 3, the screen shifts to a screen displaying a list of a plurality of game media GM owned by the player, and the game medium GM is displayed on the screen. When the operation for selecting is performed, the selected game content GM is newly registered in the deck. For example, by selecting the game medium “A” and selecting another game medium from the list of game media, the other game medium can be registered in the deck instead of the game medium “A”. When the player performs an operation input for selecting the enter button BD on the game screen GI shown in FIG. 3, the set deck is confirmed.

A game screen GI shown in FIG. 4 is an example of a game screen for playing a battle game. As shown in FIG. 4, in the first region AR ₁ of the game screen GI upper, the enemy character EC is displayed as the opponent of the player character (character). Further, on the game screen GI second region AR ₂ in the center, match a predetermined number in the game (here, four) player character PC icon IC of are displayed.

  In the game system of the present embodiment, as shown in FIG. 5, a plurality (three in this case) of player characters PC are associated with each game medium GM. For example, three player characters “a1” to “a3” are associated with the game medium “A”, and three player characters “b1” to “b3” are associated with the game medium “B”. Each player character PC has a lottery probability (winning probability) used in a lottery described later. This lottery probability is set so that the total of the lottery probabilities of a plurality of player characters PC associated with one game medium GM is 100%. For example, “70%”, “20%”, and “10%” are set as the lottery probabilities for the player characters “a1” to “a3” associated with the game medium “A”. For the player characters “b1” to “b3” associated with the game medium “B”, “65%”, “20%”, and “15%” are set as the lottery probabilities. Each player character PC is set with various parameters such as attack power and defense power, attributes, etc. (not shown).

In the game system of this embodiment, at the start of the battle game, the lottery based on the lottery probability set for each player character PC from among the plurality of player characters PC associated with each game medium GM constituting the player's deck. Thus, one player character PC to appear in the battle game is determined. For example, when the game media “A” to “D” are set as the player's deck, for the game media “A”, one player character PC is determined by lottery from the player characters “a1” to “a3”. For the game medium “B”, one player character PC is determined by lottery from the player characters “b1” to “b3”, and for the game medium “C”, the player characters “c1” to “c3” One player character PC is determined by lottery, and for the game medium “D”, one player character PC is determined by lottery among the player characters “d1” to “d3”. In the example shown in FIG. 5, the player characters “a1”, “b1”, “c1”, and “d1” have the highest probability of appearing in the game, and the player characters “a3”, “b3”, “c3”, “D3” is the character with the lowest probability of appearing in the game (rare). In the example shown in FIG. 4, among the player character PCs associated with the game media “A” to “D” constituting the player's deck, the player characters “a1”, “b2”, “c1”, “d3” "is determined as the player character PC appearing in the battle game, each icon IC is displayed in the second area AR _2.

The third region AR ₃ of the game screen GI under side shown in FIG. 4, a plurality of blocks BL for puzzle game (pieces) are displayed side by side. One of a plurality of (here, three) attributes is set in the plurality of blocks BL. Here, the first attribute block BL is marked with a circular mark, the second attribute block BL is marked with a triangle mark, and the third attribute block BL is marked with a star mark. Also, any one of the three attributes is set for the player character PC, and a mark representing the set attribute is attached to each icon IC. Here, the attribute of the player character “c1” is the first attribute, the attribute of the player character “b2” is the second attribute, and the attributes of the player characters “a1” and “d3” are the third attributes. Show. It should be noted that each block BL and icon IC are displayed in different colors with colors representing the set attributes, instead of marking each block BL and the player character PC (icon IC) with the set attribute. You may do it.

When the player performs an operation of sequentially selecting a predetermined number (for example, three) or more blocks BL of the same attribute adjacent to each other in the third area AR ₃ (tracing in the manner of one-stroke writing), all the selected blocks BL block BL is erased from the third region AR _3. In the example shown in FIG. 6, as a result of moving the fingertip touched by the user along the trajectory TR indicated by the dotted line in the figure, six blocks BL having the first attribute are selected, as shown in FIG. , the six blocks BL is erased from the third region AR _3.

When more than a predetermined number of blocks BL is erased, the player character PC of the block BL of the same attributes that are deleted out of the player character PC appearing in the competition game is displayed on the first region AR _1, the player character PC enemy A game process for attacking the character EC is performed. In the example shown in FIG. 7, since the block BL of the first attribute is selected and deleted, the player character "c1" of the first attribute is displayed in the first region AR _1, the player character "c1" is the enemy character EC Processing to attack is performed. At this time, based on the parameters (attack power) set for the player character PC that is the subject of the attack, the parameters (defense power) set for the enemy character EC, and the number of blocks BL selected / erased, The hit points of the character EC are reduced. The greater the attack power set for the player character PC, the smaller the defense power set for the enemy character EC, and the greater the number of blocks BL selected / erased, the smaller the amount of hit points of the enemy character EC. Will grow. In the case where the player character PC of the block BL of the same attributes that are erased is more than one, the game process in which the plurality of player characters PC to attack the displayed enemy character EC in the first region AR ₁ is performed.

Also, the block BL is erased in the third region AR _3, as shown in FIG. 8, region generated by the erasing, the block BL which is present in the upper direction of the erased block BL is shifted downward As shown in FIG. 9, new blocks BL (here, six blocks BL) are additionally arranged in the region generated by the shift. The attribute of each block BL additionally arranged is determined at random.

  The player performs an operation of sequentially selecting a predetermined number or more blocks BL having the same attribute adjacent to each other, and repeatedly causes an arbitrary player character PC appearing in the battle game to attack the enemy character EC. Note that the enemy character EC attacks one of the player characters PC appearing in the battle game according to a given algorithm. At this time, the total value of the hit points of the player character PC decreases based on the parameter (attack power) set for the enemy character EC and the parameter (defense power) set for the player character PC. The greater the attack power set for the enemy character EC and the smaller the defense power set for the player character PC, the greater the amount of decrease in the total value of the hit points of the player character PC. If the hit point of the enemy character EC falls below a predetermined value, it is determined that the player has won (game cleared). If the total hit point value of the player character PC falls below the predetermined value, the player Is determined to have been defeated. When the player wins, a reward is given to the player. As the reward, for example, a new game medium GM, items, experience points, points such as in-game currency, etc. are given to the player.

  According to this embodiment, a plurality of player characters PC are associated with one game medium GM, and a game is drawn by lottery from among a plurality of player characters PC associated with each game medium GM constituting the deck. Since the player character PC to be displayed in the game is determined, even if the player repeatedly plays using the same game medium GM (deck), the combination of the player character PCs that appear in the game is not always the same, and is tired. No games can be realized. This is particularly effective when the number of game media GM owned by the player is small, or when the number of game media GM that can be acquired by the player is small. For example, as in this embodiment, when four game media GM are set as a player deck and three player characters PC are associated with one game media GM, a combination of the same game media GM is used. Even if the deck is configured, there are as many as 3 to the 4th power (81) combinations of player characters PC appearing in the game.

  In addition, according to the present embodiment, the player character PC to appear in the game is determined by lottery based on the lottery probability set for each of the plurality of player characters PC associated with the game medium GM. By setting a player character PC having a high probability of appearing in the game and a player character PC having a low probability of appearing in the game (high rarity) among the plurality of player characters PCs associated with the GM, A game that prompts the player to play repeatedly until a player character PC with a high degree appears can be realized.

  Here, in this embodiment, the player can synthesize the game media GM owned by the player. In this case, the player selects a game medium GM that is a base for composition and a game medium GM that is a composition material (or a predetermined item that can be a composition material), and performs an operation for executing the composition. . When the game media GM is synthesized, the lottery probability of the player character PC associated with the game media GM selected as the synthesis base is changed. More specifically, the player character PC having the lowest lottery probability among the plurality of player characters PC associated with the game medium GM is changed so as to increase the lottery probability (the player character PC having a high degree of rarity is included in the game). Increase the probability of appearing). For example, in the example shown in FIG. 5, when composition is executed using the game medium “A” as a base and another game medium or item as a material, the lottery probabilities of the player characters “a1”, “a2”, and “a3” are , “70%”, “20%”, and “10%” are changed to, for example, “55%”, “25%”, and “20%” (that is, the lottery probability of the player character “a3” increases). ). Note that the game media GM or item selected as the composition material is deleted from possession of the player. In this way, by changing the lottery probability of the player character PC associated with the game medium GM by combining the game media GM, a game capable of prompting the player to combine (and acquire) the game media GM is realized. can do.

  Further, in the present embodiment, based on a predetermined item owned by the player (item for changing the lottery probability), a specific game medium GM (for example, the predetermined item of the predetermined item) among the game media GM owned by the player. The lottery probability of the player character PC associated with the game medium GM having the same attribute as the attribute or the game medium GM constituting the player deck) may be changed. More specifically, the lottery probability of the player character PC having the lowest lottery probability among the plurality of player characters PCs associated with the specific game medium GM is changed. Moreover, instead of changing so that the lottery probability of the player character PC having a high degree of rarity associated with the specific game medium GM based on the predetermined item is increased, the specific player specified based on the predetermined item You may change so that the lottery probability of character PC may become high. Note that the lottery probability based on a predetermined item may be changed when the player acquires the predetermined item, or when the player performs an operation of consuming (using) the predetermined item. Also good. Further, the lottery probability may be changed for a predetermined time (for example, several hours) after the player acquires or consumes the predetermined item, and the changed lottery probability is restored when the predetermined time has elapsed ( A predetermined item is a timed item whose effect lasts for a predetermined time). In this way, by changing the lottery probability of the player character PC based on the item owned by the player, a game that can prompt the player to acquire the item can be realized.

Further, in this embodiment, the lottery probability of the player character PC associated with the game medium GM constituting the deck may be changed based on the combination of the game contents GM constituting the player deck. More specifically, when a predetermined combination of game media GM is included in the player's deck, the lottery among a plurality of player characters PC associated with the game media GM related to the specific combination is selected. The player character PC having a low probability is changed so that the lottery probability is high. For example, in the example shown in FIG. 5, the specific combination is the game media “A”, “B”, “C”, and the player deck is the game media “A”, “B”, “C”, “D”. In this case, the lottery probabilities of the player characters “a3”, “b3”, and “c3” are increased. In this way, by changing the lottery probability of the plurality of player characters PC associated with the game media GM according to the combination of the game media GM constituting the deck, the game media so that the game media GM of a specific combination are arranged. A game capable of prompting the player to acquire GM can be realized.

  In the present embodiment, a plurality of player characters PC may not be associated with all of the game media GM, and only one player character PC is included in the game media GM that can be possessed (available) by the player. May be included. When such a game medium GM is included in the player's deck, a lottery for determining the player character PC is not performed for the game medium GM, and the player character PC associated with the game medium GM is included in the game. To appear.

Further, in the above example, the description has been given of the case of displaying the player character PC of the block BL of the same attribute in the first region AR ₁ when the block BL is erased, the player when the block BL is erased Control may be performed so that the enemy character EC receives an attack damage in the first area AR ₁ without displaying the character PC in the first area AR ₁ . Further, a predetermined number of the player character PC in the game is displayed from the time of starting the game in the first region AR _1, when the block BL is erased, the player character having the same attribute and the block BL in the first region AR ₁ The PC may be controlled to perform an action of attacking the enemy character EC.

3. Processing Next, an example of processing of the game system of the present embodiment will be described using the flowchart of FIG.

  First, the setting unit 110 determines whether or not there has been an operation input for selecting a predetermined number of game media GM (step S10), and if there has been an operation input (Y in step S10), the selected predetermined A number of game media GM are set as player decks (step S12).

  Next, the game progress control unit 112 determines whether or not there is an operation input for starting the battle game (step S14). If there is an operation input (Y in step S14), the player deck Is determined by lottery based on the lottery probability set for each player character PC among the plurality of player characters PC associated with each game medium (step S16).

Next, the game progress control unit 112 determines whether or not there has been an operation input for sequentially selecting a predetermined number of blocks BL or more adjacent to each other with the same attribute (step S18), and if there has been an operation input (step S18). to the Y) deletes the selected block BL from the third region AR _3, it arranged to add the same number of blocks BL in the third region AR ₃ (step S20). Next, the game progress control unit 112 performs a game process in which the enemy character EC is attacked by the player character PC having the same attribute as the erased block BL in the player character PC determined in step S16 (step S22).

Next, the game progress control unit 112 determines whether or not it is the attack timing of the enemy character EC (step S24). If it is the attack timing (Y of step S24), the player character PC is set as the enemy character EC. A game process for attacking is performed (step S26).

  Next, the game progress control unit 112 determines whether or not to continue the process (step S28), and both the total value of the hit points of the player character PC and the hit point of the enemy character EC are less than or equal to a predetermined value. If not (Y in step S28), it is determined that the process is continued, and the process proceeds to step S18, until either the total value of the hit points of the player character PC or the hit point of the enemy character EC becomes a predetermined value or less. Then, the processing after step S18 is repeated.
