Purple Diamond comes to us from 3 Oaks Gaming, built around a diamond theme and powered by a 5-reel grid running 25 paylines. The result is medium high volatility paired with an RTP of 95.36%.
The mechanics are what make Purple Diamond interesting. Look out for scatter symbols that unlock free spins and extra bonus rounds. Its medium high variance balances steady wins with the odd larger payout. All told, it's a solid entry in the 3 Oaks Gaming catalogue.
At 95.36%, 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.
Purple Diamond 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.
