Timber Stacks

Timber Stacks is a video slot from Pragmatic Play set in a pristine alpine meadow surrounded by towering trees and snow-capped mountains. The game takes place on a 5×5 grid with 3,125 ways to win initially, which can expand up to a 5×10 configuration with 100,000 ways during gameplay.

The symbols on the reels include stylized 10-A card ranks as the lower pays, along with premium symbols represented by various wildlife like a fish, cougar, owl, bear, and wolf. The wolf is the most valuable symbol, awarding 10x the bet for landing 5 of a kind. A mountain wild appears on reels 2, 3, and 4, substituting for all regular pays to help form winning combinations.

Timber Stacks utilizes a tumble mechanic, where all winning symbols are removed from the grid after paying out, allowing new symbols to fall into the empty spaces for additional wins. If no more winners are formed, there is a chance the Increasing Grid Size feature activates. This will add an empty row to the bottom of the grid and cause a random reel to collapse and fill the new spaces, expanding the game area up to 5×10 in size.

Landing 4 or 5 pawprint scatters triggers the Free Spins round, awarding 8 or 10 free spins respectively. The free spins play out on the same grid as the base game, with the Increasing Grid Size feature active. However, it seemed to trigger more frequently during testing, although this is not explicitly stated by the developer. Players outside the UK can take advantage of the Bonus Buy option to purchase the free spins for 120x the total stake.
