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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based upon and claims a priority from the prior Japanese Patent Application No. 2007-272848 filed on Oct. 19, 2007, the entire contents of which are incorporated herein by reference.BACKGROUND[0002]1. Field[0003]The present invention relates to a slot machine that executes a sub game besides a main game in which a first prize is awarded based on the symbol combination and that further awards a second prize to a player based on the result of the sub game executed.[0004]2. Description of Related Art[0005]Conventionally, in a slot machine, which is one type of gaming machine, a game is started by inserting coins or the like in the gaming machine. In the game, a symbol column is variably displayed in a predetermined area in the gaming machine, and after the lapse of a predetermined period of time, the symbol column is stopped and displayed. Then, a payout is awarded based on a combination of the symbols thus stopped.[0006]...

AI Technical Summary

Benefits of technology

[0011]Therefore, in order to achieve the object, according to a slot machine of the present invention encompassing one or more aspects thereof, there is provided 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. The processor accepts a side bet selecting one of the plurality of groups based on an operation of the bet acceptance button. The processor positions a plurality of symbols on the display. The processor identifies one of the plurality of groups having a largest number of the plurality of symbols displayed on the display classified thereto. The processor repositions the plurality of symbols so that symbols classified into a same group are positioned adjacent to each other. The processor awards a first prize based on combination of the plurality of symbols positioned on the display. The processor awards 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. As a result, it becomes possible to execute a sub game of an unprecedented new kind using symbols displayed on the display device in the slot machine. Accordingly, the slot machine can avoid the deterioration of the game tempo, thus the entertainment characteristic of the slot machine can be increased. Further, there is no need to execute different lottery programs or image process programs in the main game and the sub game, making it possible to reduce the processing load on the processor.

[0013]Furthermore, according to the present invention encompassing one or more aspects, there is provided a slot machine. The slot machine comprises a display positioning thereon a plurality of symbols, each classified into some one of a plurality of groups respectively; a bet acceptance button accepting a bet operation; and a processor. The processor accepts a side bet selecting one of the plurality of groups based on an operation of the bet acceptance button. The processor positions a plurality of symbols on the display. The processor identifies one of the plurality of groups having a largest number of the plurality of symbols displayed on the display classified thereto. The processor repositions the plurality of symbols so that symbols classified into a same group are positioned adjacent to each other. The processor awards a first prize based on combination of the plurality of symbols positioned on the display. The processor awards 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. As a result, plural symbols positioned on the display are repositioned so that the symbols classified into the same group are placed adjacent to each other. Accordingly, the player can easily grasp in which group the largest number of symbols is classified. In addition, the player can easily judge whether or not the group selected at the side bet matches the group in which the largest number of symbols are classified, namely, whether or not the condition for a prize of the sub game is satisfied.

Problems solved by technology

However, in the above-described conventional slot machine, it deteriorates the game tempo to execute as a sub game a game completely different from the main game which uses symbols displayed on the symbols.

This increases the processing load on the processor.
