Slingo Lines and Winning Structure
It is possible to secure multiple Slingo lines from a single dab. The game offers 12 win lines and 11 possible awards, as the final number on the grid always results in at least 2 winning lines being formed.
Wild Symbols
Wild symbols provide the ability to mark any number in the corresponding column above, increasing your chances of completing a Slingo line.

Super Wild Symbols
Super Wild symbols allow you to choose and mark any number anywhere on the grid, offering more flexible opportunities for progress.

Free Spin Symbols
When Free Spin symbols appear, they grant an additional spin, extending your chances to form winning lines or collect Tetriminos during regular play.

Extra Spins Feature
At the end of each game, extra spins may become available. The price of each extra spin varies depending on the current grid position and possible prizes. This cost may exceed your initial stake, and the price for the next spin is always visible on the spin button. Players can manage extra spin limits using the play controls. The availability of extra spins may vary based on location.
Potential Wins
The potential wins for your current game state are displayed during play, and the numbers still needed to achieve these wins are highlighted for reference. You may collect your winnings at any time by pressing the Collect button.
Tetris Slingo Unique Mechanics
Tetriminos
In Tetris Slingo, the following Tetriminos are featured as collectibles within the base game and as reel symbols during the Tetris Clusters feature. Each Tetrimino consists of 4 Minos (squares):

Tetrimino Collection in Slingo
Throughout standard Slingo gameplay, the grid is overlaid with various Tetriminos. There are 8 different Tetrimino layouts, determined by combinations in the base game. Players dab numbers on the grid to either complete Slingos or collect Tetriminos. Gathering 3 or more Tetriminos results in an instant cash prize. The central number on the grid is never part of a Tetrimino layout. Completing Slingos during this mode will unlock the Tetris Clusters bonus.
Tetris Clusters Feature
When triggered, Tetris Clusters can be played on one of three grid sizes:
- 3–5 Slingos: 8x8 grid
- 6–8 Slingos: 8x12 grid
- 9–12 Slingos: 8x16 grid

Tetris Clusters Gameplay Mechanics
During Tetris Clusters, the feature opens with a grid and two Tetrimino reels. At the start, these reels overlay the grid and contain a set number of Tetriminos based on the achieved grid size:
- 8x8 grid: 4 Tetriminos on a 2x2 reel
- 8x12 grid: 6 Tetriminos on a 2x3 reel
- 8x16 grid: 8 Tetriminos on a 2x4 reel
The reels spin and Minos, or coloured squares, cascade into the grid behind the reels. When the reels stop, the Tetriminos settle on the grid. Clusters are created when Tetriminos and Minos of the same colour align. A valid cluster requires at least 5 adjacent Minos of the same colour and awards are determined by the paytable. Exploded clusters lead to new Minos cascading into the grid while the Tetriminos remain set for that spin. Play continues until either all clusters have been cleared or no Tetriminos are left, after which any remaining spins repeat the cycle.
Slingo Pay Ladder and Tetrimino Collector
The Slingo Pay Ladder shows the Tetris Clusters icon to indicate the tier of grid achieved, as well as the number of spins earned for the bonus. The Tetrimino Collector tracks:
- The number of Tetriminos collected in base game
- Any marked positions on a Tetrimino
- Tetriminos still to be collected
On collecting 3 or more Tetriminos, a cash prize is awarded. The minimum possible award from the Tetrimino Collector is x1 your stake, and the maximum is x100.
Game Strategy Guidance
Optimal strategy suggests that Wilds and Super Wilds should always be used to advance the closest to a completed Slingo. If multiple positions are equally optimal, choices should prioritise those within the most potential Slingos (winning lines); otherwise, selection can be random. The central square is the most valuable as it contributes to horizontal, vertical, and two diagonal lines. If two or more Tetriminos have been collected and a single dab will complete another without the opportunity to create new Slingos, then collecting the Tetrimino is preferable. Regardless, all outcomes are determined by a Random Number Generator, and there is no strategy that ensures a win.
