Cosmic Clusters! online slot game guide
Space-themed slots often promise boundless possibilities, then fall back on a familiar grid. Scheduled for release from Pragmatic Play in July 2026, Cosmic Clusters! takes a different route. An astronaut and a cheerful alien set the scene, while coin clusters add momentum to each tumble—a less common feature in other medium-volatility slots.
Cosmic Clusters! Slot Review: Recorded Experience
The review records 200 demo spins of Cosmic Clusters! on desktop, at a €1 stake. The bonus did not trigger naturally. The reviewer bought Epic Free Spins for 1,000x the stake; the feature awarded 12 free spins and returned 1,304.55x. The base game was described as quick-paced: the first win came on spin 2, followed by more wins every 3-8 spins throughout. Its biggest base-game win was 57.25x at around spin 150. The review considered Cosmic Clusters! suitable for players comfortable with medium volatility: the base game remains active, while the feature holds the higher ceiling.

Cosmic Clusters! Theme and First Impressions
Cosmic Clusters! opts for a light-hearted look rather than an intense one. Planetoids, green-faced aliens and UFOs crossing the reels create the setting. The game seems designed for players who don't need a story to drive the action. Its most distinctive visual feature is the Money symbol system, using bronze, silver and gold coins.
In contrast to Elk Studios' Pirots series, where a space-station story accompanies the bird-collecting mechanic, Cosmic Clusters! keeps its presentation deliberately light.

How Cosmic Clusters! Plays – Base Game
Cosmic Clusters! uses a 6x6 grid. Groups of 5 or more matching symbols connected horizontally or vertically pay, then disappear. New symbols tumble in from above to fill the gaps. After each tumble, a Wild lands randomly in an open position. This Random Wild is a subtle base-game assist: it cannot guarantee a chain, but may extend one when the grid is already active.
The hit frequency is 1 in 4.08, making extended cold spells less likely, while medium volatility limits the size of the swings. The Money Symbol System adds another element. Bronze coins are worth 0.5x to 2x, silver coins 3x to 8x, and gold coins 10x to 1,000x. A cluster of at least five coins pays and explodes, leaving one coin behind with a value equal to the total paid by the coins before it.

Cosmic Clusters! Bonus Features
Free Spins
Landing 3, 4, 5 or 6 Scatters awards 12, 15, 18 or 21 FS, respectively. During the round, 2+ Scatters award two additional spins. Unlike in the base game, Money symbols that land without forming clusters fall to the bottom of the grid and stay there, accumulating over successive spins. Symbols removed in a tumble but not part of the winning combination turn into Money symbols. As the grid gradually fills, coins created on earlier spins can be collected on later ones.
Buy Feature
- Free Spins (100x) – includes all Money symbol tiers
- Super Free Spins (300x) – limited to Silver and Gold coins
- Epic Free Spins (1,000x) – limited to Gold coins
Ante Bet
- Ante Bet 1 (1.5x) – gives a 2.5x higher chance of triggering free spins
- Ante Bet 2 (2.5x) – gives a 5x higher chance of triggering free spins
What to Expect When Playing Cosmic Clusters!

Win potential and volatility
The stated maximum win is 5,000x the bet, with odds of 1 in 3,162,555. In the results described in the review, base-game wins generally stayed below 20x, though occasional spikes occurred.
Bet range and who it suits
The bet range is €0.20-€240. The review presents Cosmic Clusters! as a choice for medium-variance players seeking active sessions without spending beyond their means. Bonus hunters may also appreciate the straightforward feature ladder.

Comparing Cosmic Clusters! with Other Slots
| Slot | Cosmic Clusters! | Sugar Rush 1000 | Pirots 4 |
|---|---|---|---|
| Provider | Pragmatic Play | Pragmatic Play | ELK Studios |
| RTP | 96.45% | 96.53% | 94% |
| Volatility | Medium | High | High (7/10) |
| Max Win | 5,000x | 25,000x | 10,000x |
| Buy Feature | Yes (100x-1,000x) | Yes (100x-500x) | Yes (3x-500x) |
| Min Bet | €0.20 | €0.20 | €0.20 |
| Key Feature | Money coins + tumble + Random Wild | Position multipliers up to 1,024x | Bird CollectR + expanding grid |
Of these three slots, Cosmic Clusters! is presented as the most accessible in terms of variance, but it also has the lowest ceiling. Sugar Rush 1000, also from Pragmatic Play, offers a much higher top prize, with multipliers reaching 1,024x. Its high variance, though, makes the base game considerably leaner between bonus rounds.
Pirots 4 by ELK Studios introduces the innovative CollectR mechanic, adding complexity while pairing its space setting with more developed storylines. Of the three slots, however, it has the lowest RTP.
Verdict - Is Cosmic Clusters! Worth Playing?
Cosmic Clusters! takes Pragmatic Play's cluster pays format beyond the usual coin-based grid slot. When a cluster explodes, its entire value transfers to the new symbol, adding momentum to the base game—a feature not often found in medium-volatility games. The main drawback is its 5,000x ceiling. Based on this review, Cosmic Clusters! may appeal to medium-volatility players looking for an active session, straightforward feature access and a gentle learning curve.
