At its core, Star Supreme is a game produced by Greentube, wrapped in a fruit and star theme. It runs on a 5-reel grid running 15 paylines with a medium high-variance maths model, and an RTP of 95.1%.
The mechanics are what make Star Supreme interesting. Look out for scatter symbols that unlock free spins and extra bonus rounds. The medium high volatility strikes a middle ground that should suit most playing styles. All told, it's a serviceable entry in the Greentube catalogue.
At 95.1%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
Medium-high volatility means wins come less frequently but tend to be larger when they hit. Players should be prepared for dry spells between bigger wins, requiring a moderate bankroll.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Star Supreme features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
