Cosmic Clusters! – What Is This Slot?
Cosmic Clusters! by Pragmatic Play will be released on 16 July 2026. The game features medium volatility and is played on a 6x6 grid, with all winning symbols grouped in clusters of at least 5 symbols. The game features a space theme, with an astronaut watching over the grid filled with green aliens, flying saucers, and other space objects.
Cosmic Clusters! by Pragmatic Play features three main game components. When the player wins a cluster of symbols, the screen will tumble and all instances of that winning symbol will disappear from the screen. Any copies of that winning symbol will transform into money symbols. Any free spins rounds feature the addition of a wild symbol that can be placed in any empty space after every win on the tumble. The game features bronze, silver and gold money symbols, each of which pays between 0.5x and 1,000x the player's initial bet. Also, if the player wins clusters of 5 or more money symbols, the sum of the values of those money symbols is paid to the player, and a new money symbol of the value of the sum of those money symbols will be added to the screen.
How to Play Cosmic Clusters!
Cosmic Clusters! pays out for winning clusters rather than paylines. For a player to win, they must land 5 or more of the same symbols in a row either across the screen or along one of the rows of the 6x6 grid. The game features various winning symbols, with some paying more than others. The alien symbols pay the best, as well as the other spacecraft symbols. The multicoloured crystal symbol pays 50x the initial bet for landing 14 to 36 symbols of the same type on the screen.
- Set the total bet using the plus and minus controls. The minimum is $0.20 and the maximum is $240 in normal play. Switching on Ante Bet 1 raises the stake to 1.5x and makes the free spins round 2.5 times more likely, while Ante Bet 2 costs 2.5x the stake for a 5 times higher chance, lifting the maximum total bet to $600.
- Press Spin to play a round. Clusters of 5 or more matching symbols connected horizontally or vertically pay a win. The wild symbol substitutes for every symbol except the scatter.
- Watch the tumble after every win: the winning symbols disappear together with all other instances of the same symbols, and any of those extra instances can randomly transform into a bronze, silver or gold money symbol. A wild is added to a random empty position, the remaining symbols fall to the bottom and new symbols drop in from above. Tumbling continues until no new win forms.
- Land 3 to 6 scatter symbols to trigger the free spins feature with 12 to 21 free spins. During the round, non-winning money symbols sink to the bottom of the grid and stay in play, building toward money clusters that pay the sum of all their values.

Our Verdict
✅ Pros
- The money symbol economy is the cleverest part of the design: a paying money cluster respawns its entire total as one new coin, so wins feed back into the grid instead of leaving it. The free spins round builds on this beautifully, with non-winning coins sinking to the bottom and staying in play while disappearing symbols keep converting into fresh money. A wild added after every tumble win keeps chains alive, and the three buy tiers - up to the gold-only Epic Free Spins at 1000x - plus two Ante Bet levels cover every budget and style.
❌ Cons
- The 5,000x max win is half of what most Pragmatic Play cluster games advertise, and the round ends the moment the cap is reached. The 96.45% base RTP sits a touch under the studio's usual 96.5% mark, and the cute space theme places it in the most crowded corner of the catalogue, up against the Sweet Bonanza family of tumbling slots. Premium symbol pays are modest, with even a full grid of the top crystal symbol worth 50x, so the real money is locked behind the coin mechanics.
