Cosmic Clusters

Cosmic Clusters (Pragmatic Play) Review

Lately, Pragmatic Play hasn’t been treating us to many new titles, apparently placing even greater emphasis on quality over quantity. Still, Cosmic Clusters is set to be released on July 16, 2026. And it’s far from your average cluster-based title, with all the action taking place on a 6x6 field. There are no traditional paylines here, so Pragmatic Play invites us to form blocks of 5 or more identical icons connected vertically, horizontally, or diagonally.

Despite the massive grid and cluster mechanics with Tumble that trigger cascades, Cosmic Clusters has medium volatility. The provider also didn’t skimp on the RTP, setting a reasonable theoretical return of 96.45%, though this may vary slightly throughout the game, often in the player’s favor. And before each round, you can choose a bet size ranging from 0.20 to as much as 600 euros per spin, which shows the provider’s desire to cater to as many different types of players as possible. So the maximum prize here can reach 3 million euros, provided you’re playing at the highest bet level.

Cosmic Clusters Features Slot - Reels Screen

The game’s symbol set includes gemstones (red, purple, blue, pink, and green diamonds), which form the lowest-paying clusters. There are also crystals, an alien, a satellite, and a flying saucer, all of which can award more valuable prizes. In addition to all this, there’s also a Wild symbol in the form of an astronaut and three levels of Money icons (Bronze, Silver, and Gold) that accumulate value during active bonus rounds.

Cosmic Clusters Features

This title offers cascading reels and random Wilds starting from literally the very first round you play. So any spin could lead to a nice payout, or even several in a row. But Pragmatic doesn’t like to create games that are too run-of-the-mill, so you’re in for a few pleasant surprises.

Tumble Feature

In most slots, we spend money on every spin regardless of the outcome of the previous round. But Cosmic Clusters is completely different because the Tumble mechanic is in play here. That is, every winning attempt removes the icons that formed the cluster and replaces them with new ones. And you get at least one more chance to form a new combo. As a result, you receive a cumulative payout for all the cascades formed, which significantly increases the prize potential.

Random Wilds

Cascades are certainly very useful on their own. But that’s not all, because in this title, an astronaut acting as a Wild is placed in a random position within a former cluster. This increases the chances of a new cluster forming, allowing the cascades to continue longer, which is quite beneficial for players.

Money Icons

Sometimes Bronze, Silver, and Gold money symbols appear randomly on the grid, and each one carries an extra multiplier from a set range, for example, from x10 to as high as x1,000 for the Gold option. If you’re lucky enough to form a cluster of at least five matching Money icons, you’ll receive the total value of the multipliers attached to them. When the cluster disappears, you’re also guaranteed to receive at least one Money symbol on an empty cell. And here’s the twist: the value attached to it corresponds to the total value of the previous cluster.

FS Bonus

You’ll also find Scatters in Cosmic Clusters, and if you land at least three of them, you’ll earn between 12 and 21 FS as a bonus. Aside from the fact that you don’t pay for your spins, almost everything here works the same way as in the base game. But there’s one important detail: Money Symbols that weren’t part of a cluster drop down and remain on the grid until they form a winning cluster or the Free Spins bonus ends. What’s more, all symbols that disappear during a cascade and aren’t part of a winning combination turn into Money Symbols. Higher-value symbols also appear more frequently here, which further increases the winning potential. And if you’re lucky enough to land at least 2 more Scatters, you’ll extend the bonus by +2 FS.

Ante Bets and Buy Bonus Features

The volatility here is set to medium, which suggests fairly frequent clusters. But some bonus features don’t trigger as often as many players would like. That’s why Pragmatic has added several bonus buy options, plus enhanced bets that increase your chances of triggering the extra features.

Theme & Graphics

The theme probably isn’t the first thing you notice when playing feature-packed cluster-based games like this. But Pragmatic has really outdone itself, inviting you to explore a deliberately cartoonish universe. So, at its core, Cosmic Clusters is a fun space adventure that can lead to some pretty big payouts. You’ll likely enjoy the cascade animations, the way the Wilds behave, the sound design, the various transitions, and other features. Despite its detailed graphics, this game performs well on mobile devices.

Cosmic Clusters Free Play

We don’t recommend playing for real money right away, even with simple fruit-themed slots that have only a few paylines. This is a cluster slot featuring the Tumble mechanic, so it’s best to test it out risk-free first. Although the title is still in the works, we’ve already gained access to the Cosmic Clusters free play version for testing. Anyone who wants to can spin the reels of the Cosmic Clusters demo game using virtual credits.

Pros & Cons of the Cosmic Clusters Slot

Our Verdict

We tested Cosmic Clusters, and what really stands out here is how seamlessly the various mechanics work together. For example, even in the base game, you benefit from Tumbles and Random Wilds, which create a sense of constant motion as cascades follow one after another, building up a large multiplier. And we liked that the game’s volatility truly feels medium, so there are almost never any overly long dry spells.

The Money Symbols during the FS bonus are the real highlight of the Cosmic Clusters slot. If you’re lucky, the coins will accumulate at the bottom of the grid and eventually form a cluster with Gold coins capable of carrying multipliers of up to x1,000. Epic Free Spins featuring exclusively Gold coins theoretically always lead to colossal payouts. But the x1,000 bet cost will deter many players, and that’s not surprising. On the other hand, Super Free Spins at x300 the bet seem much more reasonable since low-value coins are cleared from the grid. If you don’t want to take big risks, you can increase your chances of triggering FS through Ante bets, though they don’t guarantee anything. In terms of mechanics and spirit, Cosmic Clusters is closest to classic cluster-based slots like Reactoonz from Play’n GO. Overall, this game is a visually rich hunt with moderate risk for a still-impressive x5,000 multiplier.
