Slot review: Cosmic Clusters

Cosmic Clusters is a Pragmatic Play slot that shoots the cluster-pays format into a colourful corner of space. The screen is packed with planets, glowing gems, alien symbols and a floating astronaut wild, giving the game a bright sci-fi look without making it feel too heavy or serious.

This is not a sequel, but it does sit close to the modern Pragmatic Play style seen in games like Sweet Bonanza, where wins can keep rolling through symbol drops and bonus rounds carry most of the bigger potential. Cosmic Clusters swaps candy for space rocks and Money symbols, which gives the familiar structure a cleaner cosmic twist.

Slot overview: Cosmic Clusters

Cosmic Clusters is played on a 6×6 grid with Cluster Pays instead of traditional paylines. Wins are formed when at least 5 matching symbols land connected horizontally and/or vertically anywhere on the grid. After a winning cluster pays, winning symbols disappear and new symbols drop into the empty spaces.

The main RTP is 96.45%, with lower versions also listed at 95.52% and 94.53%. The volatility is medium, the hit frequency is 24.51%, and the free spins frequency is listed at 1 in 294.33 spins. The base bet range is 0.20-240, or up to 600 when using the higher Ante Bet option. The maximum win is 5,000x the bet.

The game is built around a space-themed cluster base game with tumbling wins, random wilds and Money symbols that can combine into larger values.

Slot features: Cosmic Clusters

Basics: Cosmic Clusters does not use fixed paylines. A win is created when 5 or more matching symbols land connected horizontally and/or vertically on the 6×6 grid. After a winning cluster pays, the winning symbols disappear and new symbols fall into the empty spaces. Other matching copies of the winning symbol can also disappear and may be replaced by Money symbols. The process continues until no new winning clusters are formed.
Random Wilds: After every successful tumble, one wild is added to a random empty position before new symbols drop onto the grid. The wild substitutes for regular paying symbols, but not for scatters or Money symbols.
Money symbols: Cosmic Clusters includes Bronze, Silver and Gold Money symbols. Their values can range from small amounts up to 1,000x the bet. When 5 or more connected Money symbols of the same type form a cluster, their values are added together and paid. After the Money cluster disappears, one new Money symbol with the combined value is added to a random empty position, allowing values to build further during a strong sequence.
Free Spins: Landing 3, 4, 5 or 6 Scatters trigger 12, 15, 18 or 21 Free Spins. During the round, Money symbols that are not part of a winning Money cluster drop to the bottom of the grid and stay there until they are collected in a win or the feature ends. Symbols removed during bonus tumbles that were not part of the winning cluster can also turn into Money symbols. Landing 2 or more scatters during the feature awards 2 extra free spins.
Super Free Spins: Super Free Spins is a stronger bonus version available through Feature Buy. It works like the regular Free Spins round, but Bronze Money symbols are removed, so only Silver and Gold Money symbols can appear. This gives the Money cluster mechanic better average value during the feature.
Epic Free Spins: Epic Free Spins is the strongest bonus version and is also available through Feature Buy. It uses the same core bonus rules, but only Gold Money symbols can appear. Since Gold Money symbols carry the highest values, this version gives the bonus its best setup for larger Money cluster wins.
Feature Buy: Cosmic Clusters includes Ante Bet options and several bonus buys.
- Ante Bet 1 raises the stake to 1.5x and makes free spins 2.5 times more likely to trigger.
- Ante Bet 2 raises the stake to 2.5x and makes free spins 5 times more likely to trigger.
- Free Spins costs 100x the bet and starts the regular Free Spins bonus.
- Super Free Spins costs 300x the bet and starts the bonus with only Silver and Gold Money symbols.
- Epic Free Spins costs 1,000x the bet and starts the bonus with only Gold Money symbols.

Our verdict: Cosmic Clusters

Cosmic Clusters is a good Pragmatic Play release with a clean space theme and a feature set that is easy to understand. The 6×6 grid works well for this kind of cluster-pays action, and the astronaut wild gives the tumbles a little extra life.

The best part is the Money symbol system. Combining values, dropping new combined symbols back onto the grid and letting Money symbols stay active in free spins gives the bonus rounds a clear sense of growth. The Super and Epic versions also make sense because they simply improve the Money symbol pool instead of adding unnecessary extra rules.

The weaker side is in the numbers. A 5,000x max win feels modest for a modern feature-heavy cluster slot, and the bonus frequency means natural triggers can still take patience.

Our rating 7/10
