Oxygen

Oxygen is a 6x7 slot game from ELK Studios with medium-high volatility and an RTP of 94%. The reels feature multiplier mechanics, symbol transformations, wilds, a bonus game and a super bonus game. The maximum payout is listed at up to 25,000x the bet.

Three bonus symbols trigger the free drop bonus game, where multiplier values remain persistent throughout the round. A super bonus is activated when three bonus symbols appear alongside at least one persistent multiplier symbol. The game also includes Oxygen Bubbles, which double the multiplier value on each winning symbol position, plus Collector and Dealer features that gather and spread multipliers across the grid.

Other special features include the X-Blaster Wild, which can replace payout symbols in an X-shape, and the Exploding Wild, which removes payout symbols within an X-pattern above and below it. Players can use the demo version to play for free and practice before playing for real money, while X-iter offers five entry modes with different bet levels and bonus chances.
