Cosmic Clusters (Pragmatic Play) – Slot Review

Cosmic Clusters is a colourful space-themed slot set in a vibrant galaxy filled with alien creatures, UFOs, satellites, and valuable cosmic gems. The game’s bright visuals and futuristic design create a light-hearted sci-fi atmosphere rather than a traditional deep-space adventure.
The theme is reflected throughout the gameplay, with Money symbols representing valuable cosmic discoveries and tumbling wins creating the feeling of chain reactions across the galaxy. UFOs, monsters, and glowing symbols add to the game’s playful extraterrestrial style.
Overall, Cosmic Clusters combines a fun outer-space theme with cluster pays, cascading wins, and Money symbol mechanics, delivering an entertaining and visually engaging slot experience.
Cosmic Clusters is played on a 6×6 grid featuring Cluster Pays, where wins are formed by landing 5 or more matching symbols anywhere on the reels. The game offers medium volatility, a 96.45% RTP, and a maximum win potential of up to 5,000x the stake. Bets range from £0.20 to £240 per spin.
Cosmic Clusters Symbols & Pay Table

The game includes 12 symbols in total. Low-paying symbols are represented by coloured gems, while premium symbols include UFOs, Satellites, Monsters, and Gems. The Gem symbol is the highest-paying premium, awarding between 1x and 50x for clusters of 5 to 14+ matching symbols. Special symbols include Wilds, Scatters, and Bronze, Silver, and Gold Money symbols. Wilds substitute for all symbols except Scatters.
Cosmic Clusters Features & Mechanics

Tumble Feature
After every winning combination, all matching symbols involved in the win, along with any other matching symbols of the same type on the grid, are removed. Scatter and Money symbols remain in place.
Symbols that disappear but were not part of the winning cluster may randomly transform into Money symbols. Remaining symbols fall into the empty positions, while new symbols drop in from above. Tumbles continue until no new winning combinations are formed. All wins from the spin are accumulated and paid at the end of the sequence.
Random Wild Feature
Whenever a tumble results in at least one winning combination, a Wild symbol is added to a random empty position before new symbols fall onto the grid. This feature increases the chances of extending tumble sequences and creating larger cluster wins.
Money Symbols
Money symbols appear as Bronze, Silver, or Gold variants and carry random cash values:
Bronze
- 0.5x, 1x, 2x bet
Silver
- 3x, 5x, 8x bet
Gold
- 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, 1,000x bet
When a cluster of 5 or more Money symbols is formed, all values within the cluster are added together and paid instantly.
The winning Money symbols are then removed and replaced by a new Money symbol carrying the combined value of the collected cluster, creating the potential for increasingly valuable pay outs.

Free Spins
Landing 3, 4, 5, or 6 Scatter symbols anywhere on the grid triggers the Free Spins feature:
- 3 Scatters = 12 Free Spins
- 4 Scatters = 15 Free Spins
- 5 Scatters = 18 Free Spins
- 6 Scatters = 21 Free Spins
During Free Spins, any Money symbols that do not form part of a winning cluster remain on the reels and fall to the bottom of the grid, staying in place until collected or until the feature ends.
Additionally, all symbols removed during tumbles that were not part of the winning cluster automatically transform into Money symbols, dramatically increasing the frequency of Money clusters. Landing 2 or more Scatters during the feature awards +2 additional Free Spins.
Ante Bet
Players can activate optional Ante Bet modes to increase the chances of triggering Free Spins:
- Ante Bet 1 (30x Bet Multiplier) – Increases the chance of triggering Free Spins by approximately 2.5x.
- Ante Bet 2 (50x Bet Multiplier) – Increases the chance of triggering Free Spins by approximately 5x.
