Solt Machine

Abstract

Upon the start of a free game, a processor classifies symbols positioned on reels into an alphabetical character symbol group and an illustrated symbol group. Also, the processor changes the background color of the symbols into red or blue, with respect to each group. Meanwhile, the processor accepts betting for a side bet. After that, the processor repositions fifteen symbols positioned at the free game so as to make the symbols of the same group adjacent to each other. A second prize is awarded if the group selected at the side bet matches the group to which the largest number of symbols is classified among the groups to which the positioned symbols belong.

1 . A slot machine comprising:
 a display positioning thereon a plurality of symbols, each classified into some one of a plurality of groups respectively;   an operation unit accepting an operation of a player; and   a processor executing processes as follows:
 (a) a process of selecting one of the plurality of groups based on the operation of the player accepted by the operation unit; 
 (b) a process of positioning a plurality of symbols on the display; 
 (c) a process of identifying one of the plurality of groups having the plurality of symbols displayed on the display classified thereto; 
 (d) a process of awarding a first prize based on combination of the plurality of symbols positioned on the display; and 
 (e) a process of awarding a second prize based on the one of the plurality of groups selected at the process (a) and the one of the plurality of groups identified at the process (c).

 (c) a process of identifying one of the plurality of groups having a largest number of the plurality of symbols displayed on the display classified thereto; 
 (d) a process of repositioning the plurality of symbols so that symbols classified into a same group are positioned adjacent to each other; 
 (e) a process of awarding a first prize based on combination of the plurality of symbols positioned on the display; and 
 (f) a process of awarding a second prize in addition to the first prize if the side bet is accepted and simultaneously the one of the plurality of groups selected at the side bet matches the one of the plurality of groups identified at the process (c).
