This release, Diamonds Up, is the work of Red Tiger Gaming, leaning into a diamond and fruit aesthetic. It runs on a 5-reel grid running 40 paylines with medium high variance, and 95.69% RTP.
The mechanics are what make Diamonds Up 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. On balance, Diamonds Up is a no-frills option worth a few spins in the demo first.
At 95.69%, 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.
Diamonds Up 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.
