Abstract

A gaming machine which determines establishment/non-establishment of a shift condition for shifting a game mode from a normal game mode to a special game mode, shifts to the special game mode based on the determination result, and allows an instruction of A player to be inputted thereto, extracts predetermined number of card data to be used in the special game mode, selects a first and a second card data on the gaming machine side and a player side from among the extracted card data, and determines right/wrong of a designating instruction according to a result of comparison between the card data. Upon win, this gaming machine determines establishment/non-establishment of a winning combination based on the extracted card data, and when a winning combination is established, the machine performs payout corresponding to the established combination.

Claims

1. A gaming machine comprising:

a controller configured to

(a) determine, during a normal game, establishment/non-establishment of a shift condition for shifting, after the normal game, a game mode from a normal game mode to a special game mode including first and second games, the first game being different from the second game and the second game being the same as the normal game;

(b) shift, during the normal game, the game mode from the normal game mode to the special game mode based on a result of the determination in (a);

(c) extract, during the special game mode, a plurality of items of card data used in the first and second games of the special game mode at time of the shifting from the normal game to the special game mode;

(d) select, during the first game of the special game mode, a first card data as a card on a gaming machine side and a second card data as a card on a player side, from among the plurality of items of card data extracted in (c);

(e) determine, during the first game of the special game mode, a win/loss result based on a comparison between the first card data and the second card data;

(f) perform, during the second game of the special game mode, an establishment/non-establishment determination on a winning combination corresponding to the normal game, based on the plurality of items of card data extracted in (c), including the first and second cards used in the first game, in a case of win of the second card data on the player side as a result of the determination in (e); and

(g) calculate, during the special game mode, a payout of the special game mode based on a result of the establishment/non-establishment determination in (f) during the second game, wherein a payout rate for calculating the payout is changed during the calculation of the payout, in accordance with the number of times the winning combination is established during the second special games in a case where a set of the special game mode shifted after the normal game and the second special game executed in accordance with a result of the special game mode is executed a plurality of times.

2. A method for controlling games performed on a gaming machine, comprising the steps of:

(a) determining, during a normal game, establishment/non-establishment of a shift condition for shifting, after the normal game, a game mode from a normal game mode to a special game mode including first and second games, the first game being different from the second game and the second game being the same as the normal game;

(b) shifting, during the normal game, the game mode from the normal game mode to the special game mode based on a result of the determination in (a);

(c) extracting, during the special game mode, a plurality of items of card data to be used in the first and second games of the special game mode at time of the shifting from the normal game to the special game mode;

(d) selecting, during the first game of the special game mode, a first card data as a card on a gaming machine side and a second card data as a card on a player side, from among the plurality of items of card data extracted in (c);

(e) determining, during the first game of the special game mode, a win/loss result based on a comparison between the first card data and the second card data;

(f) performing, during the second game of the special game mode, an establishment/non-establishment determination on a winning combination corresponding to the normal game, based on the plurality of items of card data extracted in (c), including the first and second cards used in the first game, in a case of win of the second card data on the player side as a result of the determination in (e); and

(g) calculating, during the special game mode, a payout of the special game mode based on a result of the establishment/non-establishment determination in (f) during the second game, wherein a payout rate for calculating the payout is changed during the calculation of the payout, in accordance with the number of times the winning combination is established during the second special games in a case where a set of the special game mode shifted after the normal game and the second special game executed in accordance with a result of the special game mode is executed a plurality of times.

3. A gaming machine comprising:

a display panel for displaying a card image; and

a controller for controlling a game, the controller being configured to;

(a) extract, during a normal game, card data associating a card required to execute a poker game from a plurality of items of card data and display the extracted card data on the display panel, and in a case where a displayed game result shows establishment of a combination in the poker game, award a payout in accordance with the combination;

(b) determine whether or not the result displayed in (a) shows a trigger for shifting from the normal game to a double-down game;

(c) execute the double-down game in a case where a result of the determination in (b) shows the trigger for shifting to the double-down game,

wherein the double-down game includes;

a first game for determining a win/lose result based on a bigger/smaller comparison between numbers indicated on the card images on a player side and a machine side, respectively; and

a second game for executing the poker game during the double-down game after the first game, in accordance with a result of the first game, and

(d) determine in random the plurality of items of card data for enabling execution of each of the first and second games and display the determined plurality of items of card data on the display panel;

(e) determine the win/lose result on the player side or machine side based on input of a bigger or smaller number by the player, upon execution of the first game after the display of the plurality of items of card data on the display panel in (c);
