Lovers of Tetris rejoice! What you have here is a perfect combination of the original game mixed with some interesting cluster pay mechanics.
This Tetris Extreme slot on mobile will surprise you, in a way Tetris Super Jackpots never did. For one as you open it, you’ll get, for all intent and purposes, a Tetris game.
You have 7 reels and x amount of rows, and the classic Tetris shape will fall into place to fill the screen. Each of those little coloured squares is called a Tetrino, and much like a 5-year-old playing, there are lots of empty spaces in between all those shapes.
This is important to understand both how the wins and the multipliers work.
The first thing to happen once all the symbols fall into place is that any lines of symbols with no spaces explode and allow more symbols to fall from above.
Only that’s not a win. What that does is increase the multipliers. 1 line gives you a 1x multiplier, 8 lines give you a 10x multiplier, 15 or more lines a 50x multiplier – and all the multipliers in between.
Now, once you’ve got the multiplier set, it will calculate any cluster of symbols touching horizontally or vertically and then apply that multiplier.
If you manage to trigger 15 lines clear or more, you’ll trigger the free spins, which is played by a much better Tetris Player as you get a whole load more line formation – plus the chance to increase the multiplier by up to 5x with a special gold Tetrino symbol.
It’s a whole load of nostalgic fun to watch.
With such glowing words, why didn’t we give this a 5-star slot review? Well, if you’ve never played Tetris in your youth, this hit of nostalgia might not quite hit the mark.
For one, you may wonder why it’s a good thing that lines of symbols explode, making a potential cluster of symbols smaller and worth less.
But then again, sometimes the symbols falling from above can create even bigger clusters, so that’s about even, but can still be incredibly frustrating.
Add the fact that you only get the chance to increase the multipliers once in the free spins bonus game, and it can feel like this real money slot is trying to be difficult. If it sounds too difficult, maybe time to try a few of the other grid slots online.
But then again, Tetris was never a game that made things easy for you, and getting 250x multiplier on a big cluster of symbols will be worth for the player hardy enough to try.

Line Clear Multiplier: A full line of any colour symbol will explode and increase the multiplier. The more lines you explode the bigger the multiplier. You get more symbols falling from above.
Cluster Wins: A cluster is a group of adjacent squares of 9 or more of the same colour. These are evaluated after line clears and you get your multiplier.
Free Spins: When you clear 15 lines or more you get 10 free spins. If you clear 15 more lines during the bonus game, you re-trigger the bonus.
During the free spins, there is a chance a gold symbol will fall. If it's part of a line clear, the multiplier for that line will be multiplier by 5.
Mega Drop Jackpot: This Tetris Extreme slot has three progressive jackpots which payout totally randomly on any spin. When a jackpot drops, approximately 25% of the value paid out reseeds the jackpot amount. It can burst on any bet level but the greater the sake, the greater your chances of catching the progressive jackpot.
Finally, a Tetris slot machine that feels like a Tetris game, exploding lines, funky music and retro 90s graphics and all.
If you're not as old as some of us and never played the original, there's still some fun to be had in this Tetris Extreme slot on mobile, thanks to some big potential multipliers in both the base game and free spins.
Ultimately though, you have to enjoy a cluster pays slot machine that requires a little patience and is frustrating enough that big gamblers may soon jump to the Spartacus Legendary Warrior slot for some more classic spins.
