Cosmic Clusters!

Cosmic Clusters! is a space-themed video slot from Pragmatic Play, releasing on 16th July 2026. The game uses a cluster pays system on a 6x6 grid, replacing traditional paylines with groups of five or more matching symbols connected horizontally or vertically.

The setting follows an astronaut drifting through a colorful galaxy filled with planets, gems, and alien life. Rather than building the game around a single bonus mechanic, Pragmatic Play layered several features together: a Tumble Feature that chains wins within a single spin, a Random Wild that drops between tumbles, and a Money Symbol system where collectible coins build and pay out their combined values.

The result is a game where a single spin can develop across multiple stages before settling. Cosmic Clusters! sits at medium volatility with a 96.45% RTP, making it accessible to a wide range of players while retaining meaningful win potential up to 5,000x the total bet.

Cosmic Clusters! is set in an open stretch of space, with a purple and pink nebula background behind the 6x6 grid. An astronaut floats beside the reels, present throughout the session as wins form and the grid resets.

The symbol set is split between low and high value. Low-value symbols are colored gemstones in green, pink, blue, purple, and red. High-value symbols feature a retro UFO, a satellite, a green alien character, and a crystal formation that sits at the top of the standard pay table. Money symbols appear as metallic coins in bronze, silver, and gold, each visually distinct and easy to identify on a busy grid.

When clusters form, winning symbols disappear and new ones fall from above, keeping the grid active between each evaluation. Sound design responds to the action, building as tumbles continue within a single spin.

Cosmic Clusters! is played on a 6x6 grid. Before spinning, players set their stake using the bet controls. The default bet is set at 2.00, with a minimum total bet of $0.20 and a maximum of $240.00 per spin under standard play. Activating the Ante Bet raises the maximum to $600.00.

Spins are started using the on-screen button, or with the Space or Enter keys on a keyboard. Once a spin begins, the game evaluates all clusters automatically, pays any wins, and runs through all resulting tumbles without further input.

The paytable is accessible through the game menu and covers all symbol payouts, special symbol behavior, and feature rules. A settings panel allows sound and display adjustments at any point during a session.

Tumble Feature

After every spin, winning clusters are paid and all matching symbols disappear from the grid, including other instances of the winning symbols that were not part of the cluster, except for Scatter and Money symbols. Symbols that disappear without being part of the winning combination can randomly transform into a Money symbol. Remaining symbols fall to the bottom, empty spaces fill with new symbols from above, and the process repeats until no further winning combinations appear.

Bonus Buy Option: No

Random Wild Feature

After every tumble where at least one winning combination occurred, a Wild symbol is placed in a random empty position on the grid before the next symbols fall from above. The Wild substitutes for all symbols except the Scatter.

Bonus Buy Option: No

Money Symbols

Bronze, Silver, and Gold coin symbols appear on the grid and each carry a randomly assigned value drawn from a fixed set. Bronze coins carry values of 0.5x, 1x, or 2x the base bet. Silver coins carry values of 3x, 5x, or 8x. Gold coins carry values of 10x, 15x, 20x, 25x, 50x, 100x, 200x, 500x, or 1,000x the base bet.

When five or more Money symbols form a cluster, all their individual values are added together and paid out. A new Money symbol then appears in a random empty position carrying a value equal to the total just paid.

Bonus Buy Option: No

Free Spins

Landing 3, 4, 5, or 6 Scatter symbols anywhere on the grid triggers the Free Spins round, awarding 12, 15, 18, or 21 free spins respectively. During the round, Money symbols that land but do not form part of a winning cluster remain on the grid rather than disappearing. When tumbles occur, all symbols that disappear but were not part of the winning combination transform into Money symbols. Landing 2 or more Scatters during the round adds 2 extra free spins. Special reels are active during the feature.

Bonus Buy Option: Yes

• 100x total bet: standard Free Spins
• 300x total bet: Super Free Spins (only Silver and Gold Money symbols appear)
• 1,000x total bet: Epic Free Spins (only Gold Money symbols appear)

Ante Bet

Players can increase their stake to activate one of two Ante Bet settings. Ante Bet 1 sets a 30x bet multiplier and raises the chance of triggering Free Spins naturally to 2.5 times higher than standard play. Ante Bet 2 sets a 50x bet multiplier and raises the Free Spins trigger chance to 5 times higher. Normal play uses a 20x bet multiplier with no adjustment to Free Spins frequency.

Bonus Buy Option: No

Wins form when five or more matching symbols connect horizontally or vertically. The more symbols in a cluster, the higher the payout. All wins are multiplied by the base bet. When multiple clusters form on the same grid evaluation, all wins are added together.

Values shown are based on a $2.00 default bet as displayed in the paytable.

The Scatter symbol, shown as a flag, appears on all reels and triggers Free Spins when 3 or more land in the same spin. The Wild substitutes for all standard symbols but not the Scatter. Money symbols carry individual values and do not follow the standard payout table.

Wins form through clusters of five or more matching symbols connected horizontally or vertically on the 6x6 grid. Only the highest win is paid per individual cluster. When multiple clusters appear simultaneously, all wins are combined and added to the total for that evaluation.

The Tumble Feature extends each spin, repeating the evaluation process after each win until no further clusters form. A Wild symbol added between tumbles increases the chance of a new cluster connecting. Money symbols contribute separately, combining their values when five or more cluster together and paying out independently of the standard symbol wins.

The maximum any single round can pay is capped at 5,000x the total bet. Once that threshold is reached, the round ends immediately and any remaining features are forfeited.

Pragmatic Play's own catalog includes Cosmic Cash, which uses a different structure — a fixed 5x4 grid with 40 paylines and four jackpot prize tiers — rather than cluster pays. The space theme is shared but the mechanics are distinct. Slotmill's Coin Quest series uses a comparable coin-collection cluster system, offering a point of reference for players already familiar with that format who want to compare how Pragmatic Play applies similar ideas.

Cosmic Clusters! is a feature-rich cluster pays slot built around a layered chain-reaction structure. The combination of Tumble, Random Wilds, and Money Symbols gives each spin multiple stages of development, while three Buy Feature tiers and the Ante Bet option provide flexibility for different play styles.

Medium volatility and a 96.45% RTP make it broadly accessible, and the 5,000x cap gives meaningful upside without requiring extreme variance. The main drawback is the number of interacting mechanics, which requires some time to fully understand before a session feels intuitive. It suits players who prefer active, evolving gameplay over simpler formats.
