Systems, methods, and program products are taught which provide a slot machine game that increases the size of the symbol array as a mystery feature. As the player spins the reels, the number of positions available on each reel grows randomly to allow more paylines. Other embodiments may include free spin bonuses, as well as bonus features that further increase the number of positions on each reel, and adjust the probability of reel expansions based on the current array size. |
