How to play

If you'd rather let the reels spin for you, click AUTOPLAY to the left of the SPIN button, which allows the game to play out automatically for a set number of spins. Have fun!

Tetrimino Feature

This bonus can activate on any spin, and when it does, 1 or 2 Tetriminos will be randomly placed on or above the reels. These Tetriminos can appear as:


Tetriminos can appear as a rotated version of the symbol. All positions covered by the Tetriminos will be randomly replaced with I-TETRIMINO, O-TETRIMINO, L-TETRIMINO, T-TETRIMINO or Z-TETRIMINO. If BONUS is covered by a Tetrimino in the base game, that bonus is still counted towards any potential bonus trigger. Any position above the reel that is covered by a Tetrimino will constitute an extra row for that reel. The maximum number of rows that can be added to a reel is 4.

Free Spins Bonus

To activate the Free Spins bonus, you need to get 3 scattered Bonus symbols on reels 2, 3 and 4. During the bonus, the reels expand to contain 5 reels and 8 rows. Any spin that contains a winning combination will generate a Tetrimino Watermark. Any watermarks generated will fall to the bottom of the array, and the Free Spins Bonus will continue until a watermark break through to the top of the array.

If an entire row is covered by 2 or more watermarks, those watermarked spaces within that row will break and award a cash value. This cash value will increase if more than one row breaks in a single spin.

Jackpot Bonus

This bonus is only available during the Free Spins, and there is a chance that one of the watermarks will be generated as GOLD WATERMARK. If this becomes part of a line break combination, your Jackpot Bonus will be triggered and either the Major or the Minor Jackpot will be awarded.
