Abstract

The present invention is a gaming machine that realizes an exciting game in a video slot format. The gaming machine includes a display and a controller. The display shows reels and gauges. The reel comprises symbols. The gauges are provided so that each of them corresponds to at least one of the reels. The controller controls the movement of the symbols. One of the symbols is a specific type of symbol. The controller counts the number of how many times the specific type of symbol appears in the display reel by reel and reflects the counted numbers in the gauges. When the counted number reaches a threshold, the controller is arranged to initiate a feature on the reel whose gauge'"'"'s value reaches the threshold.

Claims

1. A gaming machine comprising:

a display, which shows groups of symbols that contain at least a specific type of symbol, the symbols being aligned along a plurality of reels;

a controller, which controls movement of the symbols in the display;

a counter, which counts a number of times that the specific type of symbol appears in each of the plurality of reels in the display;

a plurality of gauges, each of which reflect the number counted by the counter, with each gauge being provided corresponding to each reel; and

a memory, which memorizes the number counted by the counter corresponding to the reel;

wherein when the number in the memory reaches a threshold, the controller increases a winning chance in the reel that is associated with the number in the memory that reached the threshold.

2. The gaming machine according to claim 1, wherein all the symbols in the reel turn to wild symbols when the gauge reaches the threshold.

3. The gaming machine according to claim 1, wherein the specific type of symbol is a wild symbol.

4. The gaming machine according to claim 1, wherein a total number of the gauge is the same as a total number of the plurality of reels.

5. The gaming machine according to claim 1, further comprising:

a plurality of gauges for one reel; and

wherein the groups of symbols contain a plurality of different kinds of specific types of symbols;

wherein each of the specific types of symbols corresponds to each of the plurality of gauges.

8. A gaming machine comprising:

a display that shows a plurality of reels, each of the plurality of reels containing a plurality of symbols;

a controller that controls a movement of each of the symbols, and the controller counts a number of times that a specific type of symbol appears in each reel in the display;

a plurality of gauges, with each of the plurality of gauges reflecting a value of the number counted by the controller; and

wherein the controller is arranged to initiate a feature on the reel whose gauge'"'"'s value reaches a threshold when at least one of the number counted by the controller reached the threshold.

9. The gaming machine according to claim 8, wherein the display shows an availability to initiate the feature on the reel whose gauge'"'"'s value reaches the threshold.

10. The gaming machine according to claim 8, wherein the feature is initiated when the controller receives an instruction to initiate the feature.

11. The gaming machine according to claim 8, wherein the feature is a change of at least one type of symbol into another type of symbol.

wherein when one type of symbol appears in the display, a certain value is added to the gauge corresponding to the reel where the one type of symbol appeared.

15. The gaming machine according to claim 14, wherein a total number of the gauges is less than a total number of the reels.

16. The gaming machine according to claim 14, wherein a feature is initiated after the value of the gauge reaches a threshold.

17. The gaming machine according to claim 16, wherein the feature is an event that brings a benefit to a player of the gaming machine.

18. The gaming machine according to claim 16, wherein the feature is a change of all the symbols in the reel into wild symbols or a payout of a bonus credit.
