Introduction to Cosmic Clusters!
Cosmic Clusters! is a casino slot from Pragmatic Play with a space theme. Humans have over half a century of experience in space exploration, but the industry hasn’t grown as quickly as many people thought after the first astronauts set foot on the Moon in the 60s. The industry used to be a mix of cooperation and competition between nations, especially between the USA and Russia, with NASA and Roscosmos. However, even private companies, such as Elon Musk’s SpaceX, are now focusing on space travel.
This game presents an astronaut looking for valuable space gemstones. You make wins by landing symbols in a cluster, and every win results in a tumble that can lead to more wins. The loyal astronaut, who’s the game’s Wild Symbol, shows up in a random position on every tumble to increase your chances of scoring multiple wins.

Cosmic Clusters! takes us to a purple space. Comets, meteors, and gemstones are soaring through the air, and bigger planets are hovering in the back. In the lower-left corner, a golden circle spins, and above it is the game’s logo. To the right of the 6 reels is an astronaut in a white costume soaring. To make a win, you need to land at least 5 matching symbols in a cluster, connected either horizontally or vertically. The game is available on mobile phones, tablets, and desktop computers.
The lower-paying symbols in Cosmic Clusters! are green, pink, blue, and purple gemstones. They pay between 6x and 9x the bet for wins of 36 symbols. The higher-paying symbols are red gemstones, alien ships, satellites, green aliens, and bunches of gemstones. They will give you between 12x and 50x the bet for wins of 36 symbols. The Wild Symbol substitutes all symbols except the Scatter Symbol.
Special Features & Slot Mechanics
What is the max win in the slot Cosmic Clusters!?
You can win up to 5,000x the bet.
What features are available in the slot Cosmic Clusters!?
The features are Tumble Feature, Wild Symbol, Random Wild Feature, Money Symbols, Free Spins, Ante Bet, and Feature Buy.
Tumble Feature
Winning symbols will disappear whenever you score a win. The remaining symbols fall down, and new symbols are added from above. If you can make a new win when the grid is refilled, those winning symbols will also vanish and make way for new ones. A tumble continues until you’re not making any more winning combinations.
Wild Symbol
The Wild Symbol is an astronaut who substitutes for all regular-paying symbols in making winning combinations. It doesn’t substitute the Scatter Symbol.
Random Wild Feature
On every tumble, a Wild Symbol is added to a random empty position before the reels are refilled.
Money Symbols
There are three types of Money Symbols: bronze, silver, and gold. They are worth between 0.5x and 1,000x the bet. Landing 5 or more Money Symbols in a cluster will award you the cash values of all symbols.
Free Spins
Landing 3, 4, 5, or 6 Scatter Symbols anywhere on the reels awards 12, 15, 18, or 21 Free Spins. All Money Symbols that are not part of a winning cluster fall down to the bottom of the screen and stay there until a winning combination is formed.
Landing 2 or more Scatter Symbols awards 2 extra spins.
Ante Bet
You can increase the chances of triggering the Free Spins 2.5 times by using the Ante Bet 1, which will increase your base bet by 50%. Activating Ante Bet 2, which increases your base bet 2.5 times, boosts your chances of activating the Free Spins five times.
Feature Buy
You can trigger the Free Spins directly from the base game by paying 100x the bet. For 300x the bet, you get the Super Free Spins, where all Money Symbols will be silver or gold. If you want to go all in, you can purchase the Epic Free Spins for 1,000x the bet and play the feature with only golden Money Symbols.
Final Thoughts on Cosmic Clusters!
It feels like the creators of Cosmic Clusters! watched a few space documentaries and decided to add some gemstones to the dark, colorless space. The result is actually way more entertaining than it sounds. The colorful space is combined with cluster pays, tumbling wins, random Wilds, and Money Symbols that can occasionally make you feel like you've just discovered a valuable asteroid.
The cluster mechanic works great for this type of game, with enjoyable tumbles where the loyal astronaut shows up to help you. The Money Symbols add excitement even during spins that seem ordinary at first glance, while the Free Spins feature is clearly the main attraction, with the possibility of collecting extra spins and locking Money Symbols at the bottom of the screen.
The RTP of 96.45% is also solid, and the max win of 5,000x the bet is on the lower side for a game of 2026, but it’s definitely acceptable considering the medium volatility. For other space-themed slots, don’t miss Hacksaw Gaming’s Munchy Milo or Relax Gaming’s Space Attacks Dream Drop.
Cosmic Clusters! from Pragmatic Play is a fun cluster-pay slot with solid features and smooth gameplay. It may not be the next giant leap for slot gaming, but it's a pleasant journey through space that most players can enjoy without needing astronaut training.
