Cosmic Clusters! review
Cosmic Clusters! is a 2026 release from Pragmatic Play, and its rules revolve around money symbols. In a winning cluster, their values are added up and paid. In the bonus, the board stops forgetting them: money symbols that did not take part in a win stay on the grid, and symbols that disappear without helping a win are turned into more cash. The pack is short, so this review covers those rules and the numbers, and says clearly what is not published.
Money symbols inside clusters
The game pays on clusters, and the studio mentions tumbles, with symbols disappearing after a win. What sets it apart is how money symbols are treated. Whenever a winning cluster contains them, the sum of all their values is paid out. A cluster is therefore worth its regular symbol payout plus whatever cash the money symbols carry.
The pack does not list the possible money values, the minimum cluster size or the grid dimensions, so we cannot quote them. Those details are best checked in the game's own rules or the free demo.
The bonus game
Landing between three and six scatters starts the bonus game. The studio gives the range as 12 to 21 free spins, rising with the number of scatters, though the pack states only the two ends of that range, three scatters at 12 and six scatters at 21. Two scatters during the bonus award two more free spins.
In the free spins the grid behaves differently. Money symbols that are not part of a cluster remain on the grid until they are included in a win. Symbols that disappear in a tumble but were not part of the win that triggered that tumble transform into money symbols. Taken together, the board fills with cash over the course of the round, so later spins can have more money symbols available to be collected by clusters than earlier ones.
RTP, costs and the gaps in the data
One RTP is on record, 96.45%, a house edge of 3.55%. On average $35.50 is lost per $1,000 wagered. Over 100 spins a $0.20 bet costs about $0.71, a $1 bet about $3.55 and a $5 bet (a total of $500 wagered) about $17.75.
Neither a volatility label nor a max win is published for this game, so we cannot say how large the swings are or where the cap sits. Because of that, no win figures in money are given. We also have no bonus buy, ante or hit frequency data.
Games with similar numbers
Several games in the catalogue sit close on RTP. 777 Wheel Blitz lists 96.5% with a 5,020x cap, 3 Magic Eggs 96.51% and 5,000x, and Bear Crazy 96.52% and 3,900x, all from 2026. Argonauts (2025) lists 96.47% with no published cap, 777 Rush (2025) lists 96.5% and 750x, and Great Rhino from 2018 lists 96.53% and 900x.
Pros
- Money symbols in a winning cluster are summed and paid
- In the bonus, unused money symbols stay on the grid until they join a win
- Lost symbols turn into money symbols during the free spins
- Free official demo available
Cons
- No volatility label or max win is published
- The pack gives no grid size, cluster size or money values
- Few rule details, so the full bonus is hard to assess in advance
Verdict
Cosmic Clusters! is a cluster slot built around money symbols that get summed in wins and accumulate during a bonus of 12 to 21 free spins. The RTP is 96.45% and the house edge 3.55%, but volatility and max win are not published, so the size of the swings is unknown. It may appeal to players who like collection mechanics. Use the free demo to learn the rules first, and keep any real stake small.
