Cartoon aliens drift through a purple nebula on a 6×6 grid, and that's pretty much the elevator pitch for Clusteroids. Genii leaned into goofy sci-fi for this one. One-eyed orange blobs, three-eyed greens, jelly squids, tiny rocket creatures – they all stare back from a starfield while a UFO marked with a multiplier hovers off to the left, waiting for its moment.
The math is cluster pays. Five or more matching symbols touching horizontally or vertically (no diagonals) trigger a win, and then the winning batch evaporates so new symbols can fall in. That's the Cascade Wins loop, and it's where the game actually gets interesting. Every cascade nudges the multiplier upward by one step, displayed on that UFO. It climbs, holds at a ceiling, then resets only when the chain dies. So a single spin can stack quite a bit before it lets go.
Wild symbols arrive as flaming asteroids and they don't just substitute. They detonate. Each wild blows up between 3 and 8 surrounding tiles depending on where it lands, scatters excepted. It's a fun mechanic and surprisingly destructive in the right spot.
There are two scatter paths. Land four or more rocket-capsule symbols and you get Free Falls – 8, 12, or 16 of them depending on how many scatters showed up. No retrigger, which is a small letdown honestly, but the cascade multiplier carries the load. The other scatter is the Asteroid Shoot bonus, a pick-em mini-game with 4, 5, or 6 picks from six prizes. Payouts scale with the triggering bet.
A gamble round sits in the code too, the classic card-flip variety, for anyone who wants to risk a small win on a 50/50.
Bets run from $0.20 to $50 per spin, with 20 fixed lines under the hood (cluster math still applies on top). The paytable promises up to 9,775 coins on top-tier symbols, and cascade multipliers can push that further. Genii doesn't publish an RTP figure for this title, which is annoying but standard for them, so volatility sits in that medium-ish range based on the math and feature frequency. Visuals are cute rather than slick – the art style won't win awards, and the soundtrack is mild – but the cascade-plus-exploding-wild combo keeps spins moving. A solid, low-pressure cluster slot if you're not chasing 20,000x ceilings.
