Gem Fire is a title from Slot Factory, wrapped in a gem theme and powered by 5 reels and 10 paylines. The result is a very high-variance maths model paired with 94.04% RTP.
Where Gem Fire earns its keep is the feature set. Look out for scatter symbols that unlock free spins and extra bonus rounds. The very high volatility means patience is rewarded — expect quiet spells broken by bigger hits. All told, it's a serviceable entry in the Slot Factory catalogue.
The RTP of 94.04% 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.
Very high volatility delivers the most extreme payout profile — long dry spells punctuated by potentially massive wins. Only recommended for experienced players with substantial bankrolls and high risk tolerance.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Gem Fire 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.
