Slot machine having feature in which sequence of rearranging symbols on respective defined areas becomes random, and control method of the slot machine

Abstract

A slot machine scrolls symbols on a plurality of defined areas provided on a display at a time of executing a slot game, and thereafter stops the symbols on the respective defined areas. A lottery of the symbols is performed not for each of the respective defined areas but for each of the defined areas divided into a plurality of groups. Moreover, a sequence of rearranging the symbols on the defined areas is changeable, and can be made random for each unit game.

1 . A slot machine comprising:
 a display that displays a unit game in which symbols arranged on a plurality of defined areas are rearranged; and   a controller that executes:   (A) processing for deciding all the symbols to be rearranged individually on the defined areas by symbol decision processing of which number of times is smaller than a number of the defined areas;   (B) processing for deciding a sequence of rearranging the symbols on the individual defined areas; and   (C) processing for rearranging the symbols on the individual defined areas in accordance with the sequence of rearranging the symbols.   
   
   
       2 . The slot machine according to  claim 1 ,
 wherein, in a case where the rearrangement of the symbols on the respective defined areas is performed by using a plurality of rotation reels, the symbol decision processing is performed the same number of times as a number of the rotation reels.   
   
   
       3 . The slot machine according to  claim 1 ,
 wherein, in a case where the defined areas have a plurality of columns, the symbol decision processing is performed the same number of times as a number of the columns of the defined areas.   
   
   
       4 . The slot machine according to  claim 1 ,
 wherein, in a case where the defined areas have a plurality of rows, the symbol decision processing is performed the same number of times as a number of the rows of the defined areas.   
   
   
       5 . The slot machine according to  claim 1 ,
 wherein the symbol decision processing is performed the same number of times as a number of defined area groups composed by randomly selecting the defined areas.   
   
   
       6 . A slot machine, comprising:
 a display that displays a unit game in which symbols arranged on a plurality of defined areas are rearranged;   a memory that stores sequence patterns for a sequence of rearranging the symbols on the defined areas; and   a controller that executes:   (A) processing for deciding all the symbols to be rearranged individually on the defined areas by symbol decision processing of which number of times is smaller than a number of the defined areas;   (B) processing for deciding a sequence of rearranging the symbols on the individual defined areas by selecting one from the sequence patterns; and   (C) processing for rearranging the symbols on the individual defined areas in accordance with the sequence pattern.   
   
   
       7 . The slot machine according to  claim 6 ,
 wherein, in a case where the rearrangement of the symbols on the respective defined areas is performed by using a plurality of rotation reels, the symbol decision processing is performed the same number of times as a number of the rotation reels.   
   
   
       8 . The slot machine according to  claim 6 ,
 wherein, in a case where the defined areas have a plurality of columns, the symbol decision processing is performed the same number of times as a number of the columns of the defined areas.   
   
   
       9 . The slot machine according to  claim 6 ,
 wherein, in a case where the defined areas have a plurality of rows, the symbol decision processing is performed the same number of times as a number of the rows of the defined areas.   
   
   
       10 . The slot machine according to  claim 6 ,
 wherein the symbol decision processing is performed the same number of times as a number of defined area groups composed by randomly selecting the defined areas.   
   
   
       11 . A control method of a slot machine, comprising:
 (A) deciding all symbols to be rearranged individually on defined areas by symbol decision processing of which number of times is smaller than a number of the defined areas;   (B) deciding a sequence of rearranging the symbols on the individual defined areas; and   (C) rearranging the symbols on the individual defined areas in accordance with the sequence of rearranging the symbols.   
   
   
       12 . The control method of a slot machine according to  claim 11 ,
 wherein, in a case where the rearrangement of the symbols on the respective defined areas is performed by using a plurality of rotation reels, the symbol decision processing is performed the same number of times as a number of the rotation reels.   
   
   
       13 . The control method of a slot machine according to  claim 11 ,
 wherein, in a case where the defined areas have a plurality of columns, the symbol decision processing is performed the same number of times as a number of the columns of the defined areas.   
   
   
       14 . The control method of a slot machine according to  claim 11 ,
 wherein, in a case where the defined areas have a plurality of rows, the symbol decision processing is performed the same number of times as a number of the rows of the defined areas.   
   
   
       15 . The control method of a slot machine according to  claim 11 ,
 wherein the symbol decision processing is performed the same number of times as a number of defined area groups composed by randomly selecting the defined areas.   
   
   
       16 . A control method of a slot machine, comprising:
 (A) deciding all symbols to be rearranged individually on defined areas by symbol decision processing of which number of times is smaller than a number of the defined areas;   (B) deciding a sequence of rearranging the symbols on the individual defined areas by selecting one from sequence patterns for the sequence of rearranging the symbols on the defined areas, the sequence patterns being stored in a memory; and   (C) rearranging the symbols on the individual defined areas in accordance with the sequence pattern.   
   
   
       17 . The control method of a slot machine according to  claim 16 ,
 wherein, in a case where the rearrangement of the symbols on the respective defined areas is performed by using a plurality of rotation reels, the symbol decision processing is performed the same number of times as a number of the rotation reels.
