Tumble Feature – Often seen in Pragmatic Play free slots, this feature’s superpower is to remove winning symbols from view, thus creating space for new ones to land. This way, all winning symbols are removed after a winning combo, causing the remaining ones to fall to the bottom of the screen. New symbols start to fall from the top of the screen, filling in the empty cells. A tumbling session stops when there are no more wins on the reels.
Increasing Grid Size – Something else can happen when there are more winning combos on the screen – there’s a random chance for the grid to increase in size. Once the Increasing Grid Size feature is triggered, an extra row will be added at the bottom of the screen, causing a random reel to fall to the bottom. If reel 1 or 2 is chosen, all symbols present on it fall to the right to fill in the empty cells at the bottom of the screen. After the extra row is full, new symbols fall to complete the reel. If the third reel is selected, the symbols can randomly fall to the right or left, filling the newly added row. Then, new symbols are added, making the reel whole again. Finally, if reel 4 or 5 is chosen, the symbols on them fall to the left, filling the extra row. New symbols will then fall to fill the reel back to its normal format. After all tumbles in a spin end, the grid takes its standard 5×5 look.
Free Spins – Four or five Scatters can trigger the Free Spins, unlocking eight or ten Free Games. The grid can increase in size just like in the base game.
Buy Free Spins Option – The Free Spins can be instantly triggered for 120x the total current bet. The round is activated with four or five Scatters.
Ante Bet – The Timber Stacks slot has two bet modes that can be changed by the player:
- Bet multiplier 20x – triggers a normal gameplay;
- Bet multiplier 25x – increases the chances for the Free Spins to get triggered naturally with more Scatters on the reels.
