Star Clusters Slot Game Overview

The Star Clusters slot has a gem theme, with the gold-framed reels sitting in front of a pink background. As you spin the reels, you may come across various brightly-coloured gem symbols. 

The game starts with 4 rows and 4 columns in the Base Game and expands to 8 rows and 8 columns in the Free Spins. Thanks to the Megaclusters feature, the symbols can split and react, potentially resulting in up to 256 symbols in the Free Spins round.

This slot has an above-average Return To Player (RTP) rate of 96.54%, and it is available to play online at Pay By Mobile Slots.

How To Play Star Clusters

To start playing Star Clusters, players need to select their stake by using the left and right arrow buttons on the stake display. The stake value is shown in the stake display, and all payouts are multiplied by the chosen stake. The available betting range goes from £0.20 up to £5.00 per spin.

Once the stake is set, simply press the Play button to initiate the spin. The 4 reels spin and come to a stop, revealing the result. The goal is to land 5 or more identical symbols of any size horizontally or vertically adjacent to each other to form winning clusters.

Features & Symbols


Star Clusters is a Megaclusters game that introduces a revolutionary symbol-matching mechanic. In the Base Game, the grid starts with 4 rows and 4 columns, which can expand to 8 rows and 8 columns during the Free Spins.

If a winning cluster is formed, each winning symbol splits into four smaller symbols. If new winning clusters are created with these smaller symbols, the process repeats, and symbols of the same size above them collapse downwards, making room for new symbols to fill the vacant positions on the board. This chain reaction continues until no more wins occur.


The Regular Wild symbol substitutes for all symbols except the Gold Wild. The Gold Wild, on the other hand, can substitute for any symbol on the reels. Up to two Gold Wilds can appear during gameplay.

It's important to note that Wild symbols only substitute for adjacent symbols and do not contribute to cluster wins. They solely serve as valuable tools to potentially help create or enhance winning combinations.

Gold Wild Multiplier

The Gold Wild Multiplier is an exciting feature in Star Clusters. It starts at x1 and increases by +1 whenever one or more Gold Wilds substitute in a win. This multiplier increment occurs before any wins are paid.

However, it's essential to remember that the Gold Wild Multiplier resets at the end of each spin unless the Free Spins feature is triggered. 

Free Spins Feature

If 5 or more reactions occur in the base game, the Free Spins feature activates. You receive 2 Free Spins plus an extra spin for each reaction after the 5th. 

The Gold Wild Multiplier carries over from the triggering game (if present), and each time the Gold Wild Multiplier reaches a multiple of 10 during this feature, it awards an additional 2 spins.

Paylines & Ways To Win

Star Clusters does not have traditional paylines. Instead, it utilises the Megaclusters mechanic, where wins are achieved by forming clusters of 5 or more matching symbols. Clusters involve the symbols landing in adjacent positions horizontally or vertically. The more symbols in a cluster, the higher the payout. 

The highest win is paid per winning cluster, and all winning combinations are added together. Payouts are multiplied by the chosen stake.


Star Clusters offers stunning visuals and exciting gameplay. The Megaclusters mechanic provides a unique twist to traditional mobile slots, helping shake things up from typical payline slots. It also has a high RTP of 96.54%, which is above the average for online slot games. In addition to this, it has incredible bonus features, including Free Spins and a Gold Wild Multiplier.

However, it is important to remember that Star Clusters is a random game of chance, and there are no guarantees of winning or triggering bonus features. Please gamble responsibly and never bet money you aren't comfortable losing.
