Tetris Extreme (Red7/SG Digital): Overview

I sat down with Tetris Extreme from Red7/SG Digital and that Korobeiniki theme hit straight away. The 7x10 grid fills with tetromino blocks, lines clear, new blocks drop, and a meter climbs. Wins land on clusters of nine or more same-colour squares after the drop sequence ends. Bets run from 20p to £100 a go. The left-side multiplier can rise to x50 in the base game, so even modest clusters can add up when a tidy run of line clears builds momentum.

Tetris Extreme (Red7/SG Digital): Features

In Tetris Extreme the mechanic is simple to read once you’ve spun a few times. Clear lines and the Line Clear Multiplier steps up, topping out at x50 in the base. Hit 15 line clears in one spin to trigger 10 Free Spins. During Free Spins a Gold Tetromino can drop; if any line uses it, the current multiplier is multiplied by 5. I've seen the bonus meter push past 100x on runs, but it resets when the run breaks, so you need a clean chain to land big.

There’s a Mega Drop progressive option on many builds of Tetris Extreme. A slice of each stake feeds three jackpots named Minor, Major and Epic, which can trigger at random. The Mega Drop version also comes with a stronger RTP at about 96.09%, while the standalone sits around 94.09%. All blocks pay the same regardless of colour, with 25+ squares paying 8x stake before multipliers. It’s a different rhythm to standard reels, yet the loop of clears and drops is easy to follow.

Tetris Extreme (Red7/SG Digital): Verdict

Tetris Extreme takes a moment to click, and early spins can feel slow as lines resolve, but it grows on you. When the meter stacks high, the hits can be tidy. On paper the top looks about 2,500x stake if a 25+ block cluster meets a 100x readout, though in my sessions big bonuses were rare and many smaller pays padded the gaps. If you like the soundtrack and favour cluster runs with a rising multiplier, this one does the job.
