Tetris Extreme is an incredibly fun Tetris-branded slot developed by Red7 that doesn't really feel like a slot! If anything this wonderful title could quite easily pass as a brand new version of the original 1984 game, it's that good! With base game multipliers of up to 50x, bonus round multipliers of up to 250x AND a three-tiered progressive jackpot, it's not hard to see why we highly recommend playing this fantastic retro video game-themed slot.

Tetris Extreme Features

Tetris Extreme has one main bonus feature and a number of cool mechanics that make it stand out from the crowd. First and foremost we have special symbols and different ways to win spins. 

On each spin single blocks, line blocks or tetrominos can land. A tetromino is a geometric shape composed of four squares that you'd find in the original Tetris game. These can be rotated by 90, 180 or 270 degrees before appearing, helping form a winning line. Players can also form wins by landing a cluster of blocks together that are all the same colour as each other.

Every time a line is removed from the game a multiplier climbs up, starting at 2x and reaching a total of 50x during base gameplay. 

Players can trigger a free spins bonus round if they manage to remove 15 lines from the game in one single spin, during the free spins a multiplier climbs up to 250x in total, this is achieved by landing golden tetromino blocks which can boost the multiplier by 5x. 

If all of the above wasn't quite enough for you then there's also the opportunity for players to win one of three progressive jackpots! These are the Minor, Major and Epic Jackpots that make up the Mega Drop Jackpot. The main Epic Jackpot can reach up to a tasty £200,000, so it's well worth playing for!

Golden Tetrominos

During the free spins round a golden tetromino may appear, if it does and it forms a winning line then the overall line clear multiplier will be multiplied by 5 at the end, leading to some huge wins. 

Cluster wins

If a group of blocks land next to each other that the same colour then they'll be removed from the game as a cluster and new blocks will fall into play.

Free Spins

If players manage to consecutively remove 15 lines from the game on a single spin then they'll automatically trigger the game's free spin feature.

Mega Drop Jackpot

This slot is part of the Mega Drop Jackpot network, meaning that players can win one of three jackpots. The Minor, Major and Epic jackpots.

Tetris Extreme

Tetris Extreme is a truly unique branded slot developed by Red7 that plays just like the famous real-life video game, all the way down to the recognisable soundtrack, which is a fast-paced techno version of the 1984 original!

Rather than utilise symbols and reels, this slot sees players register wins each time a full line of blocks appear on the game screen, whenever a line is cleared a multiplier climbs up (to a total of 50x) and a new set of blocks come into play!


We have to give some major props to Red7 as this game is wonderfully designed. Behind the reels is a hypnotic scene featuring thousands of shining stars spread across a vast purple galaxy, at the bottom of the game screen is a strange rotating sphere.

The game screen itself is designed to emulate an actual Tetris screen, rather than having reels or symbols we simply have blocks in all sorts of shapes and sizes that you'd see in the original game. 

When you start spinning the reels a modern take on the original Tetris theme song 'Korobeiniki' plays. It's still the same old Russian folk song you know and love, but it's got a cool techno vibe to it which gets especially heavy during free spins.

All in all Red7 have done an absolutely stellar job of giving this franchise the love it so rightly deserves, some developers don't go to all the lengths to make a branded slot feel like it's actually part of the brand, but that's certainly not the case here.


As we mentioned, players register wins every time a full line of blocks appears on the game screen (regardless of colour), whenever a line has cleared a multiplier on the left-hand side of the reels climbs up (to a total of 50x) a new set of blocks come into play! If players manage to clear 15 lines in total on just one spin then they'll automatically trigger 10 free spins!

Win Potential

This medium volatility 2019 slot has an RTP of 95.09%, which is a little bit lower than we like to see. In terms of maximum winning potential, players can win a maximum of 2,500x their stake which again isn't anything groundbreaking, but it's still enough to tempt us to play... Especially when you remember this game is linked to SG Digital's Mega Drop Jackpot network.

Our Verdict

Honestly, we loved playing Tetris Extreme! Any game that strays from the norm will grab our attention, and this is one of them for sure! The increasing multipliers made for some lucrative wins and the free spins round was particularly exciting. Don't let the fairly low win potential put you off.
