Where Square Up earns its keep is the feature set. 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. Overall it's a well-rounded release that knows what it is.
The RTP of 94.02% is below the industry average of ~96%. This is common for older slots or those with special features. The lower RTP may be offset by unique mechanics or higher maximum win potential.
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.
Square 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.
