Abstract

A gaming machine having a display device for variably displaying and stopping symbols during a game; a memory storing a lottery table having interrelated random number ranges, threshold target values (an accumulatively counted number of times the game has been played) and payouts; and a processor (a) to extract a random number, (b) to determine from the lottery table the random number range to which the random number belongs, (c) to determine the threshold target value corresponding to the determined random number range, (d) to accumulatively count a total number of times the game has been played while games are continuously conducted, (e) to determine whether or not the total number of game plays equals the determined threshold target value, and (f) to determine from the lottery table and give the related payout when the total number of game plays equals with the determined threshold target value.

Claims (40)

1. A gaming machine comprising:

a display device for variably displaying and stopping symbols during a game;

a memory storing a lottery table, the lottery table having interrelated random number ranges, threshold target values and payouts corresponding to each of said random number ranges, each threshold target value being defined as an accumulatively counted number of times the game has been played; and

a processor programmed to operate with the display device and the memory

(a) to extract a random number,

(b) to determine from the lottery table the random number range to which the random number belongs,

(c) to determine the specific threshold target value corresponding to the determined random number range,

(d) to accumulatively count a total number of times the game has been played while games are continuously conducted,

(e) to determine whether or not the total number of times the game has been played equals the determined specific threshold target value, and

(f) to determine from the lottery table and cause the display device to display the related payout and provide the payout to the player when the total number of times the game has been played equals with the determined specific threshold target value.

2. The gaming machine according to claim 1 , wherein the memory includes plural lottery tables,

wherein the processor respectively determines one threshold target value from each of the lottery tables, and

wherein the processor gives the related payout each occurrence that the total number of times the game has been played reaches one of the determined threshold target values.

3. The gaming machine according to claim 2 , wherein the processor determines a last-in-sequence threshold target value among the determined threshold target values of the plural lottery tables,

wherein the processor determines whether or not the total number of times the game has been played equals with the last-in-sequence threshold target value, and

wherein the processor resets the total number of times the game has been played when the total number of times the game has been played equals the last-in-sequence threshold target value.

4. The gaming machine according to claim 1 , wherein the processor starts notification indicating that the related payout will be given when the total number of times the game has been played reaches a predetermined value smaller than the determined threshold target value.

5. A gaming system in which plural gaming machine and a server are connected,

each of the gaming machines comprising;

a display device for variably displaying and stopping symbols during a game; and

a gaming machine processor programmed to operate with the display device

(a) to conduct a lottery to determine a stop display manner of the symbols on the display device,

(b) to control the display device to stop the symbols according to the stop display manner, and

(c) to provide a payout based on the stop display manner of the symbols;

the server comprising:

a memory storing a lottery table, the lottery table having interrelated random number ranges, threshold target values and payouts corresponding to each of said random number ranges, each threshold target value being defined as an accumulatively counted number of times the game has been played and

a server processor programmed:

(d) to extract a random number

(e) to determined from the lottery table the random number range to which the random number belongs,

(f) to determine the threshold target value corresponding to the determined random number range,

(g) to accumulatively count-up a total number of times the game has been played while the games are continuously conducted in the gaming machine,

(h) to determined whether or not the total number of times the game has been played equals the determined threshold target value, and

(i) to determine from the lottery table and give the related payout to the gaming machine when the total number of times the game has been played equals the determined threshold target value.

6. The gaming system according to claim 5 , wherein the memory includes plural lottery tables,

wherein the server processor is programmed to determines one threshold target from each of the lottery tables, and

wherein the server processor is programmed to provide the related payout to the gaming machine each occurrence that the total number of times the game has been played reaches one the determined threshold target values.

7. The gaming system according to claim 6 , wherein the server processor is programmed to determines a last-in-sequence threshold target value among the determined threshold target values of the plural lottery tables,

wherein the server processor is programmed to determines whether or not the total number of times the game has been played equals the last-in-sequence threshold target value, and

wherein the server processor is programmed to resets the total number of times the game has been played when the total number of times the game has been played equals the last-in-sequence threshold target value.

8. The gaming system according to claim 5 , wherein the gaming machine processor is programmed to starts notification indicating that the related payout will be given when the total number of times the game has been played reaches a predetermined value smaller than the determined threshold target value.
