Aviamasters X-mas is BGaming's festive flight game, replacing the aircraft with Santa's sleigh and the carrier with an ice floe. The round balance grows through additive and multiplicative pickups, while ice obstacles halve it. A landing on the floe pays the final balance; a landing in the water loses the round. Switching among the four presentation speeds changes how quickly the animation is shown, rather than creating a manual cashout opportunity. This landing-based settlement is the important distinction from crash games that ask players to stop a rising multiplier.
