Overview
Journey into space for an intergalactic adventure in Pragmatic Play’s Cosmic Clusters slot. Played on a 6x6 grid with Cluster Pays, join aliens, UFOs and spaceships at online slot sites, from 20p a spin.
With wins formed when you land 5+ matching symbols connected horizontally and/or vertically, winning clusters lead to tumbles for continuous wins. Each tumble triggers the Random Wild feature: a Wild symbol is added in a random empty position before new symbols drop in.
Look out for Money symbols, which are worth up to 1,000 x your total bet: when a cluster of 5+ Money symbols form, the values of all Money symbols are combined and awarded. A new Money symbol with a value equal to the win is added randomly on the grid.
There is a Free Spins feature where you begin with up to 21 free spins. All Money symbols that are not part of a winning cluster remain on the grid until a winning cluster forms with them. All instances of symbols that are removed during tumbles and are not part of a winning cluster transform into Money symbols. You can also win more free spins.
With a 96.45% RTP rate, Cosmic Clusters comes with 5,000 x bet max wins: try the free-play version below. For the top games in the UK, head to OLBG’s demo slots section for hundreds of options.

More Space-Themed Titles
Want to play more space-themed slots? There is a top 10 list that see you encounter galaxies, aliens and semi-automatic drones. Below are 3 of the top 10 games in a little more detail:
Starburst (NetEnt)
- RTP: 96.09%
- Max Win: 500x
- Volatility: Low

Starburst is NetEnt's iconic space-themed classic, released June 2012 and still a slot site staple. Played across 5 reels and 10 paylines with Win Both Ways technology, the focus is on the Starburst Wilds: a Starburst Wild land on any of the 3 middle reels expands to a fully wild reel and triggers a re-spin, stacking up to 3 wild reels and 3 re-spins. Whilst the max win potential of 500 x bet is modest, it’s one of the most popular online slot games ever and often the subject of no wager free spins offers.

- Max Win: 147,620x
- Volatility: Very High

The Free Spins feature introduces Power-Ups: multiplier boosts, double increases, scatter retriggers, more ways to win and transformations. With even more in the enhanced version, it offers 147,620 x bet max win potential.

- RTP: 96.47%
- Max Win: 50,000x
- Volatility: High
- Stakes: 10p to £5
- Release Date: 8 February 2022
