US Patent 7770891 Method for providing multi-game reel strips

A method for varying the symbols used on a mechanical reel strip are disclosed. A reel strip comprises a plurality of symbols, each of the symbols associated with a symbol group. Each of the symbol groups is associated with a symbol group designation position on the reel strip. By varying the designation position on the reel strip, the symbols used with each reel strip can be modified. When multiple mechanical reels are used in a gaming machine, the symbol designating position for each reel strip can be the same as any other reel strip or can vary from any of the other reel strips. As such, an endless number of games and game variations may be created and deployed.
