Oxygen Tested
Across a catalog of 140+ Elk Studios releases, Oxygen was the title we found ourselves going back to. You'll find an underwater motif done with care, not pasted on. This review breaks down the reels piece by piece below.
How Much Can It Pay?
The stake range starts at 0.20 and climbs to 100 — room for every budget. Over 7 paylines and 7 reels, win frequency stayed honest during testing. Fix a session limit before the first spin; Oxygen stays fun that way.
A Look at the Reels
Symbol art runs yellow, pink, orange and green fish — on-theme and readable even at speed. Wild work goes to the wild — keep it across the reels. Bonus-trigger work belongs to the bonus chest and multiplier bubbles — position does not count, just the count. The wild-and-scatter combo hands Oxygen dual engines toward surprise payouts.
Rounds and Free Play
Trigger three bonus symbols and Oxygen's Free Drops takes over — arguably the game's best stretch. Beyond the first feature, three bonus symbols and a persistent multiplier feature opens the Super Bonus. Then there's a third: the Avalanche. Round four, the Big Symbols, takes things further. Count the Cluster Wins to the list too. Feature frequency felt fair across the review sessions — neither starved nor flooded.
