Timber Stacks

In "Timber Stacks," a video slot created by Pragmatic Play, players find themselves in a lively forest filled with various wildlife such as wolves, bears, owls, and fish, all framed by stunning mountain landscapes. The game features a base grid of 5×5, where players create winning combinations by aligning symbols from left to right. A distinctive Tumble mechanic is included, which removes winning symbols after each win, allowing new symbols to fall into place for additional chances to win. If a tumble sequence does not yield a win, the Increasing Grid Size feature may randomly trigger, adding empty rows at the bottom and collapsing one of the reels to fill those spaces, potentially enlarging the grid to 5×10 and providing up to 100,000 ways to win. Wild symbols appear on the second, third, and fourth reels, substituting for all regular symbols except for the Scatter. To initiate Free Spins, players must land four or five Scatter symbols, which awards eight or ten free spins, respectively. An Ante Bet feature is offered in select regions, increasing the chances of triggering Free Spins for a slight rise in the wager. In areas where it is allowed, a Bonus Buy option enables players to purchase direct entry to the Free Spins round for a multiple of their bet. During the Free Spins, players will enjoy the same expanding grid mechanics as in the base game, enhancing the excitement of grid expansions.
