About this Slot
Star Clusters is a space-themed slot from Big Time Gaming with an RTP of 96.54%, very high volatility and a maximum win of 34,500x.
The game uses a Megaclusters mechanic where winning symbols are replaced by four smaller symbols. These smaller symbols create new wins, which are then removed as identical symbols drop down to fill the gaps. This chain reaction continues until no further wins occur, at which point the grid resets to its default size.
Scatters only trigger through reactions during the cascade sequence. Four or more scatters award 10 Free Spins, with each scatter beyond the fourth granting 1 additional spin.
During Free Spins, the Wild Multiplier begins at x1 and increases by +1 with every reaction. This multiplier applies to all wilds that appear in winning clusters throughout the feature.
Additional scatters landing during the bonus round award +4 spins, with each scatter beyond the fourth adding 1 more spin to the remaining total.
A Feature Buy option is available, allowing direct entry into the bonus round.
