Timber Stacks™ at 1xBet: Ways-to-Win and Tumble Mechanics

Grid and ways-to-win awards

Play starts on a 5x5 grid that can randomly extend for individual spins up to a maximum of 10x5. At the maximum 10x5 size, the maximum number of ways to win is 100000. All symbols pay from left to right on adjacent reels starting from the leftmost reel.

Only the highest win is paid per winning combination on the same pay way, and when winning on multiple pay ways, all wins are added to the total win.

Wild symbols

The WILD symbol substitutes for all symbols except for SCATTER. The WILD appears on reels 2, 3 and 4.

Tumble feature and win settlement

In the TUMBLE FEATURE, after every spin the winning combinations are paid and all winning symbols disappear; the remaining symbols fall to the bottom of the screen and the empty positions are replaced with new symbols coming from above. Tumbling will continue until no more winning combinations appear as a result of a tumble.

All wins are added to the player's balance after all of the tumbles resulted from a base spin have been played.

Increasing Grid Size trigger and reel movement

After every spin or tumble, if there are no more winning combinations on the screen, there is a random chance that the INCREASING GRID SIZE feature triggers. When it happens, one more empty row of symbols is added to the bottom of the grid, and a random reel is selected to fall to the bottom.

If reel 1 or 2 is selected, all symbols from it fall to the right; if reel 3 is selected, its symbols fall randomly either right or left; if reel 4 or 5 is selected, its symbols fall to the left.

In each case the symbols currently on the reel are added, from bottom to top, in as many positions as are empty at the bottom, and new symbols then fall from the top to fill the reel that fell. After all tumbles from the same spin end, the grid resets back to 5x5.

Free spins trigger and award

Landing 4 or 5 SCATTER symbols triggers the FREE SPINS feature and awards 8 or 10 free spins respectively.

Free spins round contents and settlement

During the free spins round, the INCREASING GRID SIZE feature is available and behaves like in the base game, and special reels are in play during the feature. Free spins and bonus wins are added to the pay way win, and the free spins win is awarded to the player after the round completes.

Bet multiplier options

The player can select the bet multiplier, and the game behaves differently depending on the selected bet. At bet multiplier 25x, the chance to win the FREE SPINS round naturally is higher, more SCATTER symbols are present on the reels, and the BUY FREE SPINS feature is disabled. All wins are multiplied by base bet.

Free spins buy option

In certain jurisdictions, the free spins bonus round can be purchased for 120x the player's bet, triggering at least four Scatters on the next spin.
