Gemza X-mas by BGAMING is a 5x5 slot with pays anywhere mechanics, a separate reel beneath the main field, and a refilling system that can extend a single spin through multiple consecutive wins. The game uses gemstone symbols, scatter triggers, and multiplier symbols ranging from x2 to x500. It has very high volatility, an RTP of 97.17%, and a maximum win of €250,000.
Four or more scatter symbols activate 15 free spins, with 3 or more additional scatters during the bonus round awarding 5 more spins. The free spins feature also collects multiplier values into a common total that is applied to later winning spins in the round. A bonus game with Keys Multipliers is triggered by finding 4 old chests full of diamonds.
Players can use the demo version to play for free and practice before playing for real money. The slot also includes Buy Bonus and Chance x2 features, which affect access to free spins, while the extra reel can add five more symbols to each spin and complete winning combinations.
