Cosmic Clusters

What Cosmic Clusters has actually done in our bonus hunts

We have opened Cosmic Clusters 7 times across 7 separate bonus hunts between 16 Jul 2026 and 24 Aug 2026 and recorded every result. Across those 7 opens the median result was 83× the bet, against 50.1× for every slot in our recorded dataset. The biggest single result we have recorded on it is 248.45×. 3 of those 7 opens were 100× or better. 7 opens is a small sample and describes only these recorded sessions — it is not this slot's RTP and it does not predict what your next bonus will do.

Pragmatic Play launches Cosmic Clusters into orbit, floating an astronaut against a backdrop of planets, stars and drifting gas clouds that shifts to a reddish tone once the bonus round kicks in.

Set on a 6x5 grid, the game pays via clusters rather than fixed lines, connecting groups of five or more matching symbols either horizontally or vertically. Coloured gems in green, pink, blue, purple and red fill the lower end of the paytable at 0.15x to 1x the bet for the smallest qualifying cluster, while UFOs, satellites, green aliens and crystals occupy the top tier, worth 6x to 50x for the largest connected groups. A wild symbol substitutes for anything on the paytable when it appears.

After a cluster pays out, every instance of the winning symbols clears from the grid, with the remaining pieces dropping down and fresh ones falling in from above — and any non-winning symbol removed during that process has a chance to turn into a Money symbol instead of vanishing outright. This keeps tumbling until no further wins land, and any tumble that does produce a win adds a wild to an empty grid position before the next symbols drop. Money symbols themselves carry bronze, silver or gold values worth anywhere from 0.5x up to 1,000x, and gathering five or more of them into a cluster pays their combined total, explodes them, and drops a fresh Money symbol worth exactly what was just won into an open space.

Scattering three, four, five or six bonus symbols opens a free spins round worth 12, 15, 18 or 21 spins depending on the count, and landing two or more adds a couple of spins on top of whatever's already been won. Through the round, any Money symbol that lands outside a winning cluster sinks to the bottom of the grid and stays there until it's eventually used or the spins run out, while the same conversion of vanishing symbols into Money symbols keeps happening in the background. Ante bets are available too, raising the stake by 1.5x or 2.5x in exchange for a better shot at triggering the free spins, and three separate buy-in options let players jump straight into the bonus — one general entry, one that limits the drop to silver and gold Money symbols only, and a pricier one restricted to gold alone.

Cosmic Clusters carries a medium-volatility rating with an RTP of 96.45% at its top configuration, a hit frequency of roughly 1 in 4.08, stakes from 0.20 to 240 per spin, and a maximum win of 5,000x the bet.
