A slot machine includes an option in which the probability of an outcome is influenced by changing the probability of one or more symbols occurring on one or more reels (reel, reel, . . . ) by randomly or pseudo-randomly selecting reels from a set of two or more reels. The probability can be adjusted by changing, adding or subtracting symbols on a reel strip.

Methods and apparatus for slot machine games

A method for awarding a jackpot, and a corresponding gaming machine and system are disclosed. The jackpot is awarded based upon the presence of scatter symbols appearing in the game outcome in a predefined manner. The jackpot is preferred to be linked across multiple machines. In a preferred form, scatter symbols on one reel may be in an active or inactive state, the jackpot is awarded only if they are in the active state, and the probability of them being in an active state is dependent upon the size of the player's wager, so as to provide linear returns to players.
