Head into the wilderness and stack up winning combinations with Timber Stacks.

Symbols including fish, owls, bears and wolves appear on this game's 5×5 grid, with players needing to land matching symbols from left to right to award a win. A special mountain Wild can also land on the second, third and fourth reels, substituting for all symbols except the Scatter.

A tumble mechanic sees winning combinations removed from play and replaced by others, creating multiple chances to win on a single spin. If no more winning combinations remain, the reels can spontaneously increase in size. This mechanic sees one of the stacks fall to the bottom of the grid, potentially expanding it to 10×5 and providing players with up to 100,000 different ways to win. Once tumbles have finished, the grid will return to its original size.
