Abstract

A method for operating a rotating reel type slot machine, or a video machine which depicts rotating reels, is described herein which allows a player to save in memory one or more symbols from one or more previous games and use those symbols in a current game to obtain a winning combination. The display glass of the slot machine contains an area for displaying the symbols which have been saved.

a display portion displaying a plurality of rotatable reels, each reel having a plurality of symbols on its periphery;

a means for rotating said reels and stopping said reels such that at least two symbols on each reel are displayed to a player of the slot machine across at least two horizontal paylines;

a selector for allowing said player to store at least two of said displayed symbols per reel as one or more saved symbols in a memory for use in a subsequent game, said selector being available for use by said player to store said symbols after each game, stored symbols being available for use by said player for multiple subsequent games;

a display area associated with each of said rotatable reels for displaying said one or more saved symbols of said respective reel; and

an award means for awarding a payment to said player for winning combinations of symbols using both said one or more saved symbols and currently displayed symbols for determining a winning combination of symbols.

2. The slot machine of claim 1 wherein said display portion comprises said rotatable reels rotated by a motor.

3. The slot machine of claim 1 wherein said display portion comprises an electronic display for displaying said rotatable reels on a display screen.

4. The slot machine of claim 1 wherein said selector comprises a plurality of buttons associated with each of said rotatable reels, wherein depression of one of said plurality of buttons stores a displayed symbol on an associated reel as a saved symbol in said memory for use in a subsequent game.

5. The slot machine of claim 1 wherein said selector comprises a different selector for each of said rotatable reels.

6. The slot machine of claim 1 wherein said rotatable reels comprise a first reel, a second reel, and a third reel, said selector comprising a different selector for each of said rotatable reels, wherein activating a selector for one of said rotatable reels causes a displayed symbol on said one of said rotatable reels to be saved for use in combination only with symbols displayed by the remaining rotatable reels.

7. The slot machine of claim 1 wherein said rotatable reels comprise a first reel, a second reel, and a third reel, said selector comprising a different selector for each of said rotatable reels, wherein activating a selector for one of said rotatable reels causes a displayed symbol on said one of said rotatable reels to be saved for use in combination with displayed symbols on any of said rotatable reels.

8. The slot machine of claim 1 further comprising a means for canceling one or more of said saved symbols in said memory after a payment to said player has been made for a winning combination utilizing one or more of said saved symbols.

rotating reels in said slot machine, each reel having a plurality of symbols around its periphery;

stopping said reels to display at least two symbols on each reel in a particular symbol combination;

selecting two or more displayed symbols for at least one of said reels to be saved and stored in a memory, said machine allowing a player to perform said step of selecting after each game, stored symbols being available for use by said player for multiple subsequent games;

displaying said saved symbols in a display area associated with the respective reel;

rotating each of said reels subsequent to said step of selecting;

stopping said reels to display at least two symbols on each reel in another particular symbol combination; and

determining a payment to a player for a winning combination of symbols using both saved symbols and currently displayed symbols for determining a winning combination of symbols.

10. The method of claim 9 wherein said step of selecting comprises pressing a button associated with each of said reels to save a symbol displayed by an associated reel.

11. The method of claim 9 wherein symbols saved during said step of selecting are used in combination with any other symbols displayed by said reels for determining a winning combination of symbols.

12. The method of claim 9 wherein symbols saved during said step of selecting are used in combination only with symbols on reels other than the reel associated with the saved symbol, for determining a winning combination of symbols.

13. The method of claim 9 further comprising the step of canceling one or more saved symbols once it has been determined that a winning combination of symbols uses said one or more saved symbols in combination with one or more currently displayed symbols on said reels.
