Big Time Gaming’s Star Clusters online slot game features the developer’s Megaclusters mechanic, and starts with a 4x4 grid in the base game. When symbols are involved in a winning cluster, they split into four smaller symbols that can spin independently, increasing the number of symbols on the grid and the win potential with every chain reaction.
Imagery is basic, with different-coloured gem symbols and star wilds, but the game’s intricate win mechanism, medium-high volatility, and wins up to 23,000x make up for the simplistic artwork.
Create chain reactions with winning clusters to unlock the free spins bonus game, where unlimited win multipliers and retriggers offer heaps of prize potential.

The 4x4 grid is encased in gold and set against a vibrant yellow background. Green buttons to the side house your game controls. Use the left and right arrows to toggle through your wagering options and set your bet, then hit the play button to start spinning.
Regular pay symbols are different coloured gemstones, which appear with two bonus symbols on the reels: Regular wild symbols are multicoloured stars on a black background, and gold wilds are gold stars on a multicoloured background.
Land clusters of five or more matching pay symbols connected on horizontal or vertical sides to trigger base game payouts indicated in the game’s paytable.

Big Time Gaming developers are masters of understatement, packing heaps of bonus features into what initially appears to be an unassuming game.
Megaclusters is a proprietary mechanic from Big Time Gaming that combines cluster pays with chain reactions. Each time a winning cluster of five or more matching symbols hits, the Megaclusters engine kicks in and, after payouts, each winning symbol splits into four smaller symbols, which then all spin independently for a second chance to win.
The maximum number of symbols that can appear on the base game grid is 64 when all 16 symbols have split.
When a win involving these smaller symbols occurs, they explode from the reels, and the symbols of the same size above them on the grid will collapse downwards, making room for new symbols to drop in from above. This chain reaction continues until no further wins occur.
Each reaction lights up one spot on the Reactions Meter at the sides of the grid. Lighting up the entire meter triggers free spins.
Regular wild symbols appear anywhere on the grid, and substitute for all symbols except gold wilds to help you create winning clusters. Gold wilds can substitute for all other symbols, and a maximum of two can land at any one time.
The Gold Wild Multiplier is displayed at the top of the game grid. It starts at x1 and increases by +1 whenever one or more gold wilds are involved in a winning combo, as is applied to winning payouts. The Gold Wild Multiplier resets between base game spins.
When five or more reactions occur in a row in the base game, the free spins bonus is activated, awarding two free spins plus one more for each additional reaction beyond the fifth.
The free spins bonus is played on a modified 8x8 bonus grid, where it’s possible to see up to 256 symbols when all regular symbols are split into four smaller ones.
The Gold Wild Multiplier carries over from the main game into the bonus and remains sticky between spins. A Retrigger Meter is visible above the bonus grid and increases with the Gold Wild Multiplier whenever a gold wild is involved with a win. Each time all ten segments light up, two more free spins are added to your count.
