The size of the Grid is dependent on how many Slingos have been collected:

– 6-8 Slingos: Tetris Clusters plays out on an 8×12 Grid.
– 9-12 Slingos: Tetris Clusters plays out on an 8×16 Grid.
The different levels of Tetris Clusters are represented on the Slingo Payladder by the following icons:

|---|---|---|
 |  |  |
| 3 Slingos = 2 Spins | 6 Slingos = 4 Spins | 9 Slingos = 4 Spins |
| 4 Slingos = 4 Spins | 7 Slingos = 8 Spins | 10 Slingos = 10 Spins |
| 5 Slingos = 8 Spins | 8 Slingos = 12 Spins | 12 Slingos = 16 Spins |
 |  |  |
Tetris Clusters Gameplay
The Tetris Clusters features a Grid and 2 Tetrimino Reels.
At the start of the feature, 2 Reels containing Tetriminos overlay the Grid.
The number of Tetriminos in the Reels is dependent on which Grid has been achieved by the collection of Slingos in Tetris Slingo:
– 8×8 Grid: contains 4 Tetriminos on a 2×2 Reel
– 8×12 Grid: contains 6 Tetriminos on a 2×3 Reel
– 8×16 Grid: contains 8 Tetriminos on a 2×4 Reel
The Reels spin and coloured squares, known as Minos, cascade behind the Reels.
Once the Reels stop spinning, Tetriminos stop in place on the Grid.
Clusters are formed when Tetriminos and Minos match.
A Cluster consists of 5+ adjacent Minos of the same colour.
Clusters pay according to the Paytable below.
After a Cluster has exploded and Cash has been awarded, more Minos cascade into the Grid.
The Tetriminos remain in place from the original spin and no new Tetriminos appear in the spin.
Once all Clusters are complete, or no Tetriminos remain, the spin ends.
Any additional spins then play out and follow the pattern above.
Pay Table
| Cluster Size | 8×16 Grid | 8×12 Grid | 8×8 Grid |

Slingo Information
Best Strategy
The best strategy dictates that the selection for positions of Wilds and Super Wilds is always in the position that will move the player closer to completing a Slingo.
Where multiple positions with the same criteria are available, the preference is given to positions which are included in the most Slingos (win lines). Where this is not applicable, a random choice is made.
For example the central square would be given preference since it is included in a horizontal, vertical and two diagonal lines.
The exception to this is where at least 2 Tetriminos have been collected, a Tetrimino is a single dab from collection and no Slingo lines can be collected from this dab.
At this point, dab to collect the Tetrimino.
Please note that no strategy can result in a win, as this game is random, using a Random Number Generator.
