Cat Wilde and the Doom of Dead is a 5-reel, 3-row video slot machine with 10 fixed paylines. Wilds can land on any reel, and all Wilds expand to fill the reel. 3 Scatter symbols appearing on reels 1, 3 and 5 trigger an initial 10 Free Spins. 10 additional Free Spins can be earned during the mode by getting 3 Scatter symbols on reel 1, 3 and 5. Number of Free Spins are unlimited! Before Free Spins begins, a symbol is chosen from any of the high or low-paying symbols to become a Special Expanding Symbol during the entire Free Spins sequence. After prizes for regular winning combinations have been recognized, the Special Expanding Symbol may expand to cover all three positions on its reel. This symbol will only expand when it is part of a winning combination. The Special Expanding Symbols do not need to appear adjacent to each other to result in a winning combination. Wild symbols can create winning combinations with the Special Expanding Symbols as well.
