Timber Stacks

Starting on a 5x5 grid, Timber Stacks offers a unique expanding mechanism that allows the grid to grow up to 10 rows high. The base game provides 3,125 ways to win, with matching symbols creating wins from left to right on adjacent reels. After each win, the tumble feature removes winning symbols, allowing new ones to fall into place and create more wins. Symbols in the Timber Stacks slot range from standard cards to forest wildlife such as fish, cougars, owls, bears, and wolves. A wild also appears only on reels 2, 3, and 4 to help create winning combinations by substituting for all symbols except scatters. The game's standout feature is its Increasing Grid Size mechanic, which can trigger after any non-winning spin or tumble. When activated, a new row appears at the bottom, and symbols from a randomly selected reel cascade either left or right to fill it. This innovative system can increase the winning ways to 100,000. There are also free spins that you trigger by landing four or five scatters.
