Gaming Machine Accepting Bet Applicable To A Series Of Games And Control Method Thereof

Abstract

A gaming machine of the present invention includes: a memory; an input device capable of placing a BET on a predetermined number or less of numerals out of plural numerals; and a controller programmed to execute the processing of: (B) storing BET-numeral information showing the numeral having the BET placed thereon, into the memory; (C) repeatedly executing processing of determining a specific number of numerals out of the plural numerals, for plural games, after having accepted the BET; (D) storing a piece of specific-numeral information showing the determined specific number of numerals, into the memory, every time determining the specific number of numerals in processing (C); and (E) offering a payout, based on the number of numerals overlapping between the numerals shown by the BET-numeral information stored into the memory in processing (B) and the numerals shown by every piece of specific-numeral information stored into the memory in processing (D).

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a gaming machine accepting a BET applicable to a series of games and a control method thereof.[0003]2. Discussion of the Background[0004]Conventionally, there are known various games (e.g. WO 07 / 016,776-A, US 2007 / 0026947-A1, and U.S. Pat. No. 5,413,351). Further, in Asia, KENO is known as a familiar game from old times.[0005]KENO is widely known as a game of ancient China, and is a game in which a player predicts 20 numerals to be chosen by lottery out of 80 numerals from 1 to 80 and places a BET. At the time of placing a BET, the player selects between 1 and 15 numerals from the numerals ranging from 1 to 80. Then, a payout will be offered according to the number of numerals matched between the numerals selected by the player and the numerals determined by the lottery.[0006]When the player selects numerals in KENO, a payout is determined based on one lottery result. The payout is gener...

AI Technical Summary

Benefits of technology

[0011]The probability that the numerals having the BET placed thereon overlap with the numerals shown by every piece of the specific-numeral information determined by multiple-times lottery processing and stored in the memory is lower than the probability that the numerals having the BET placed thereon overlap with the numerals shown by the specific-numeral information determined by one-time lottery processing and stored into the memory. Hence, according to the gaming machine, it is possible to make the payout large as the probability decreases, and also to offer a payout attractive to the player.

[0045]Also, the probability of winning the numerals having the BET placed thereon decreases as the number of games inputted by the player increases. Hence, according to the control method of a gaming machine, it is possible to make the payout large as the probability decreases, and also to offer a payout attractive to the player.

Problems solved by technology

Hence, the payout tends to be small in the conventional KENO, and the payout offered has not always been attractive to the player.
