Abstract

A slot machine according to the present invention comprises: a symbol display; and a controller programmed to execute the processing of shifting a mode to an insurance mode on condition that a game medium is inserted, stop-displaying plural symbols sequentially after variable display thereof, determining, in a state that only the last one symbol is variably displayed, whether or not a stopping state of the stop-displayed symbols satisfies a specific condition that may generate a payout of the game medium when the last one symbol is stop-displayed, counting numbers of specific games, in each of which the last one symbol is stop-displayed after the specific condition has been determined to be satisfied, for a plurality of the specific conditions respectively, after shifting the mode to the insurance mode, and paying out game media, when determining that any of the numbers of the specific games has reached the predetermined number.

Claims

1. A slot machine comprising:

a symbol display capable of variably displaying a plurality of symbols; and

a controller,

said controller programmed to execute the processing of

(A) shifting a mode from a non-insurance mode to an insurance mode on condition that a predetermined number of game media is inserted,

(B) stop-displaying said plurality of symbols sequentially, after variably displaying said plurality of symbols to said symbol display,

(C) determining, in a state that said symbols have been sequentially stop-displayed in said processing (B) and only the last one of said symbols is variably displayed, whether or not a stopping state of the stop-displayed symbols satisfies a specific condition that may generate a payout of the game medium when the last one of said symbols is stop-displayed,

(D) determining whether or not the stopping state of the stop-displayed symbols is a stopping state not generating the payout of the game medium, when the last one of said symbols is stop-displayed after said specific condition has been determined to be satisfied in said processing (C),

(E) counting numbers of specific games, in each of which the stopping state of said symbols has been determined to be the stopping state not generating the payout of the game medium in said processing (D), for a plurality of said specific conditions respectively, after shifting the mode to said insurance mode,

(F) determining whether or not any of said numbers of the specific games has reached a predetermined number, and

(G) paying out a predetermined number of game media, when determining that any of said numbers of the specific games has reached said predetermined number in said processing (F).

2. The slot machine according to claim 1,

wherein

said controller is further programmed to execute the processing of

(H) resetting only said number of the specific game satisfying said specific condition, said number of the specific game being determined to have reached said predetermined number.

3. The slot machine according to claim 1,

wherein

said controller is further programmed to execute the processing of

(I) resetting both of said numbers of the specific games satisfying said specific conditions, said numbers of the specific games each determined to have reached or not to have reached said predetermined number.

4. A slot machine comprising

a symbol display capable of variably displaying a plurality of symbols;

and

a controller,

said controller programmed to execute the processing of

(A) stop-displaying said plurality of symbols sequentially, after variably displaying said plurality of symbols to said symbol display,

(B) determining, in a state that said symbols have been sequentially stop-displayed in said processing (A) and only the last one of said symbols is variably displayed, whether or not a stopping state of the stop-displayed symbols satisfies a specific condition that may generate a payout of the game medium when the last one of said symbols is stop-displayed,

(C) determining whether or not the stopping state of the stop-displayed symbols is a stopping state not generating the payout of the game medium, when the last one of said symbols is stop-displayed after said specific condition has been determined to be satisfied in said processing (B),

(D) counting numbers of specific games, in each of which the stopping state of said symbols has been determined to be the stopping state not generating the payout of the game medium in said processing (C), for a plurality of said specific conditions respectively,

(E) determining whether or not any of said numbers of the specific games has reached a predetermined number, and

(F) paying out a predetermined number of game media, when determining that any of said numbers of the specific games has reached said predetermined number in said processing (E).

5. A control method of a slot machine, said control method comprising the steps of:

(A) shifting a mode from a non-insurance mode to an insurance mode on condition that a predetermined number of game media is inserted;

(B) stop-displaying a plurality of symbols sequentially, after variably displaying said plurality of symbols to a symbol display;

(C) determining, in a state that said symbols have been sequentially stop-displayed in said step (B) and only the last one of said symbols is variably displayed, whether or not a stopping state of the stop-displayed symbols satisfies a specific condition that may generate a payout of the game medium when the last one of said symbols is stop-displayed;

(D) determining whether or not the stopping state of the stop-displayed symbols is a stopping state not generating the payout of the game medium, when the last one of said symbols is stop-displayed after said specific condition has been determined to be satisfied in said step (C);

(E) counting numbers of specific games, in each of which the stopping state of said symbols has been determined to be the stopping state not generating the payout of the game medium in said step (D), for a plurality of said specific conditions respectively, after shifting the mode to said insurance mode;

(F) determining whether or not any of said numbers of the specific games has reached a predetermined number; and

(G) paying out a predetermined number of game media, when determining that any of said numbers of the specific games has reached said predetermined number in said step (F).

6. A control method of a slot machine, said control method comprising the steps of:

(A) stop-displaying a plurality of symbols sequentially, after variably displaying said plurality of symbols to a symbol display,

(B) determining, in a state that said symbols have been sequentially stop-displayed in said step (A) and only the last one of said symbols is variably displayed, whether or not a stopping state of the stop-displayed symbols satisfies a specific condition that may generate a payout of the game medium when the last one of said symbols is stop-displayed,

(C) determining whether or not the stopping state of the stop-displayed symbols is a stopping state not generating the payout of the game medium, when the last one of said symbols is stop-displayed after said specific condition has been determined to be satisfied in said step (B),

(D) counting numbers of specific games, in each of which the stopping state of said symbols has been determined to be the stopping state not generating the payout of the game medium in said step (C), for a plurality of said specific conditions respectively,

(E) determining whether or not any of said numbers of the specific games has reached a predetermined number, and

(F) paying out a predetermined number of game media, when determining that any of said numbers of the specific games has reached said predetermined number in said step (E).
