Big Time Gaming’s Star Clusters 2 is a high-volatility sequel that builds on the original’s Megaclusters mechanic with a sleek, Tron-inspired aesthetic. Set in a digital afterlife for AI entities, this slot features a 4x4 grid that expands to 8x8 in free spins, where cascading reactions and wild multipliers up to x100 can lead to massive wins. With a max payout of 34,500x, unlimited multipliers, and a feature buy option, Star Clusters 2 offers a futuristic twist on cluster-based gameplay.
Star Clusters 2 does not have the usual paylines but requires matching symbols in a cluster (a.k.a. cluster pays) instead. The game has several features including Buy Feature, Cascading Reels, Cluster Pays, Megaclusters, Multiplier Wilds, Random Multiplier, Retrigger, and more. Star Clusters 2 also has a free spins bonus round and this is usually where you can win the big money.
The standard RTP (Return to Player) for Star Clusters 2 slot is 96.63% (Could be lower on some sites). This payback considered very good and higher than average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €96.63. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 34500x your total bet which is very high and gives you the chance to win really big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
Star Clusters 2 is a volatile slot, and Big Time Gaming rates the volatility High (4/5). Volatility, in the context of slot games, refers to how often and how much a slot game pays out. Star Clusters 2 is designed to appeal to those who enjoy the adrenaline rush of substantial winnings that low volatility slots can't deliver, and are willing to accept the inherent risks of less frequent payouts.
Star Clusters 2 is a visually striking and mechanically rich slot that rewards patience and risk-taking. The reactions system and wild multipliers create thrilling momentum, especially in free spins. However, the high volatility, complex mechanics, and variable RTP may deter casual players. A solid pick for fans of BTG’s experimental style and those chasing big multipliers.
