Full Rules & Information About the Cosmic Clusters Online Slot

Cosmic Clusters has a big game zone with a 6×6 grid of reels offering a colourful feast for the eyes. The game uses a cluster-pays system rather than the traditional fixed paylines that many new slots still use.

Multipliers are not part of the action on Cosmic Clusters, and jackpots are absent too, but the game does have a low minimum bet at UK online casinos.

Cosmic Clusters Symbols & Payouts

Slots symbols on Cosmic Clusters start with different gems as the low-pays, with the more premium icons including aliens and UFOs. The top-paying slot symbol on Cosmic Clusters is a cluster of crystals, while players must land at least five matching icons to trigger the tumble mechanics on the new slot.

Premium pays include space-themed icons like UFOs and aliens.

• All symbols: 9
• Highest-Paying Symbol: Crystals
• Wilds: Random Wilds
• Paylines Pay: Cluster Pays
• Maximum Win: 5,000x the stake size

Cosmic Clusters Bonuses & Features

The cluster pays system on Cosmic Clusters means that every time a bunch of matching slot symbols land, they disappear with new icons appearing in their place.

Icons that disappear are also able to transform into money symbols, which are shown on the reels as coins. These are valued at 0.5x-2x the stake size for bronze coins that drop on Cosmic Clusters, which improves to 3x-8x for silver coins.

Gold coins pay out an impressive 10x-1,000x the stake size, with five of the coin money symbols needed in a cluster for these to explode and pay out.

Six scatters in the base game award 21 free spins.

The main slot feature on Cosmic Clusters is the bonus game, with at least three scatters needed to earn free spins. Three scatters award 12 free spins, with more paid for extra scatters, all the way up to 21 free spins for six scatters.

Any coin money symbols that land in the bonus round stay on the reels, but drop to the bottom until enough of them are in place to form a cluster. This is the main part of the action and how the biggest wins can happen on Cosmic Clusters.

Another two free spins are also awarded if two scatters land from a free spin, so it is possible to extend the fun further on Cosmic Clusters as well.

Similar Games & Best Alternatives

The look and feel of the new slot by Pragmatic Play is certainly reminiscent of classic game Starburst, while Slotmill’s hit Coin Quest seems to be another inspiration.

Leading releases from Pragmatic Play that remain very popular at UK online casino sites include Sweet Bonanza and Caishen’s Gold, with the latter title having an above-average RTP of 97.08%.

Pragmatic Play’s New Slot Packs In Action

New slots from Pragmatic Play drop so regularly at UK online casinos that it can be hard for players to keep track, but Cosmic Clusters has enough variety to help it find fans and stand out from the crowd.

The addition of money symbols provides something a little different, and the chance to earn 21 free spins to start the bonus round is very generous, though the maximum win of 5,000x the stake size is a bit low compared to some new slots.
