Abstract

A lottery value defining unit included in a pachi-slot machine is performed to make a first number range according to a first internal win different from a second number range according to a second internal win that is different from the first internal win. Furthermore, the lottery value defining unit is performed to make a third number range according to a third internal win, which is different from the first and second internal wins, at least partially overlapped with the first and second number ranges. The overlapped ranges of the first and second number ranges with the third number range are different from each other.

Claims

1. A gaming machine comprising:

a symbol display unit for displaying a plurality of symbols;

a start operation detector for detecting a start operation by a player;

a random number sampling unit for sampling a random number from a predetermined number range, based on the detection of the start operation performed by the start operation detector;

a lottery value defining unit for defining an upper limit value and a lower limit value of a number range within the predetermined number range in accordance with an internal win;

a random number determining unit for determining whether or not the random number sampled by the random number sampling unit is within the number range, through comparing the value of the random number sampled by the random number sampling unit with both the upper and lower limit values;

an internal win determining unit for determining an internal win according to the number range when the random number determining unit determines that the random number sampled by the random number sampling unit is within the number range;

a variable display control unit for controlling the symbol display unit to variably display the symbols, based on the detection of the start operation by the start operation detector;

a stop operation detector for detecting a stop operation by a player;

a stop control unit for controlling the stop of the variable display controlled by the variable display control unit, based on the detection of the stop operation by the stop operation detector and an internal win determined by the internal win determining unit; and

a game value offering unit for offering a game value when a predetermined symbol combination is displayed in a stop mode by the symbol display unit through the stop control by the stop control unit,

wherein the lottery value defining unit is performed to make a first number range according to a first internal win different from a second number range according to a second internal win that is different from the first internal win, and to make a third number range according to a third internal win, which is different from the first and second internal wins, at least partially overlapped with the first and second number ranges, wherein the overlapped ranges of the first and second number ranges with the third number range are different from each other.

2. A gaming machine comprising:

a symbol display unit for displaying a plurality of symbols;

a start operation detector for detecting a start operation by a player;

a random number sampling unit for sampling a random number from a predetermined number range, based on the detection of the start operation performed by the start operation detector;

a lottery value defining unit for defining an upper limit value and a lower limit value of a number range within the predetermined number range in accordance with an internal win;

a random number determining unit for determining whether or not the random number sampled by the random number sampling unit is within the number range, through comparing the value of the random number sampled by the random number sampling unit with both the upper and lower limit values;

an internal win determining unit for determining an internal win according to the number range when the random number determining unit determines that the random number sampled by the random number sampling unit is within the number range;

a variable display control unit for controlling the symbol display unit to variably display the symbols, based on the detection of the start operation by the start operation detector;

a stop operation detector for detecting a stop operation by a player;

a stop control unit for controlling the stop of the variable display controlled by the variable display control unit, based on the detection of the stop operation by the stop operation detector and an internal win determined by the internal win determining unit;

a game value offering unit for offering a game value when a predetermined symbol combination is displayed in a stop mode by the symbol display unit through the stop control by the stop control unit; and

a setting value selector for selecting a setting value of a ball payout rate indicative of a ratio of total game value offered to a player by the game value offering unit to the total game value to be betted, among a plurality of predetermined values,

wherein the lottery value defining unit is performed to make the number range according to any one of internal wins and the number according to other internal win, which is different from the one internal win, at least partially overlapped within the range according to the setting value selected by the setting value selector.
