Oxygen slot review
Provider: ELK Studios
Mechanics: Clusters · Cascades · Multipliers
Volatility: ░░░░█ High
RTP: 94% ⚠️ below market average
Max win: 25,000x bet
The main feature
Multipliers don't reset — they build directly on the grid. Every new win doubles their value. When Collector and Dealer land on the field at the same time, a single cascade series can change everything.
How it works
A 6×7 grid, no paylines. Wins are collected in clusters of 4+ symbols, and the grid refreshes through cascades after each hit. The logic is simple: the longer a series runs, the more aggressive the multipliers become.
🫧 Oxygen Bubbles — every winning combination doubles the multiplier on each winning symbol position
🎯 Collector — gathers all active multipliers into one value. Can remain persistent on the grid between spins
📡 Dealer — multiplies all multipliers in its radar direction. Can also stay persistent
✖️ X-Blaster Wild — captures a random symbol and replaces matching symbols across the grid in an X-shape
💥 Exploding Wild — clears payout symbols in an X-shaped zone, opening space for new combinations
When it explodes
The base game can run quietly — multipliers build up without visible reward. Everything shifts when Collector and Dealer meet in the same cascade series. That's when accumulated value turns into an explosion.
Bonus — three bonus symbols trigger the free drop bonus game. All multipliers carry over and keep growing.
Super Bonus — if at least one persistent multiplier is already on the grid when the bonus triggers, the Super Bonus activates instead. Stronger starting conditions, higher ceiling.
X-iter™ — ELK's unique entry mechanic: five modes ranging from 3x bet (more than triple the bonus trigger chance) to 500x bet (guaranteed persistent multiplier in the Super Bonus). A rare way to tailor the game to your own playing style.
