How to play Oxygen 3 (members only)
Wins pay for groups of matching symbols that touch horizontally or vertically. Larger clusters pay more, and winning clusters usually disappear to make room for new symbols.
Oxygen 3 is played on a 6×7 grid with cluster pays.
- Set your stake. Choose your total bet per spin between $0.20 and $100. Wins are paid as multiples of this stake.
- Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.
- Spin. Each spin's result is decided by a certified random number generator, independent of previous spins.
- Optional bonus buy. Where permitted, pay a fixed price to start the bonus directly.

How winnings work (members only)
What 96% RTP costs per $100 wagered, the 25,000x max win at a $1 stake
The top prize is capped at 25,000x your stake. On a $1 spin that is $25,000; on $0.20 it is $5,000. When the cap is reached the round usually ends immediately.
Because wins don't depend on lines, every symbol in view can count towards a pay. The paytable lists how many matching symbols each tier needs.
Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.
What 96% RTP means
Expected return = stake × 96%
Over $100 of total bets, the long-run average loss is $4.00
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium–high volatility game.
The published hit frequency is 33%, meaning roughly one spin in 3.0 returns something — though many of those wins are smaller than the stake.
Features explained (members only)
6 features explained: multipliers, wild symbols, bonus buy, multiple bonus buys and more
Multipliers
Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
Bonus buy
Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).
Multiple bonus buys
Several feature-buy options at different prices, each starting a different version of the bonus round.
Symbol upgrades
Lower-paying symbols are transformed into higher-paying ones during a feature.
Cluster pays
Wins are formed by groups of matching symbols touching horizontally or vertically, rather than along lines.
Strategy tips (members only)
- Size your stake to the volatility. Medium-to-high volatility means longer gaps between meaningful wins, with most of the return concentrated in features. Use smaller stakes relative to your budget. A simple rule: bring at least 250 spins' worth of budget, so a $50 budget suggests a stake of about $0.20.
4 more tips and a session planner
- Check which RTP version you're playing. ELK Studios offers this game at 96%, 87%. Open the game rules at your casino and prefer sites running the 96% version.
- Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
- Bonus wagering: at 96% RTP, clearing $1,000 of wagering costs about $40.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
- Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
