How to play Oxygen slot: Features, symbols, and gameplay
Oxygen drops you into a bold 6x7 grid, where wins form through cluster connections. Instead of reels, symbols fall in Avalanches, keeping gameplay alive as new symbols drop in. Each round starts with a fresh cascade, building tension as chains of wins unfold.
Paylines
Oxygen doesn't follow the traditional paylines mechanic. Instead, wins form from clusters of at least 5 matching symbols linked vertically or horizontally. Only the biggest cluster pays per drop. With Avalanches, winning clusters vanish, symbols fall, and new ones land, giving more shots at wins in one round.

Soft glimmers rise from the sea floor, where shells rest like hidden gems. These low-paying symbols shine with quiet charm, giving steady bursts of wins that sparkle through water. They may not bring the largest riches, but their glow keeps the quest alive.

| Symbol | Set of 5-8 | Set of 9-11 | Set of 12-13 | Set of 14+ |

Bold and full of life, the high-paying symbols light the grid with playful charm. Their vivid designs cut through the calm, sparking thrill with each cluster drop. These are the treasures that make the ocean floor shine, offering wins that feel larger than life.

Multipliers
Oxygen brings Multipliers alive with its Oxygen Bubbles, which stick to symbol spots on the grid. When a cluster lands, the spot gains a 1x Multiplier. Each win on the same spot doubles the value. These Multipliers stay through the drop, fueling consecutive wins in Avalanches.
The game adds twists with unique Multiplier boosts, such as:
- Collector: Gathers all Multipliers in view and stacks them on its spot when part of a win. This boost can roll into a Bonus Round for bigger wins.
- Dealer: Takes its Multiplier and spreads it across one or more V-shaped zones. Each Multiplier in that zone increases, with a multiplier of at least 2x. Like the Collector, the Dealer can stay active in bonus rounds, helping Multipliers stack into huge rewards.
Wild symbols
Wilds replace any paying symbol to help form cluster wins. These symbols can pack explosive power, offering more wins and more clusters forming.
There are special Wild symbols, such as:
Exploding Wilds
They burst when included in a win. After the last Avalanche ends, they detonate. The blast clears paying symbols in an X shape above and below itself. This frees space for fresh drops and can trigger more features.
X-Blaster Wilds
When triggered, a paying symbol or Wild transforms all connected symbols in an X-shaped pattern. If Exploding Wilds or other X-Blasters lie in its path, they ignite as well. Overlapping X-Blasters multiply the effect, converting every hit symbol into a Wild and setting the stage for massive clusters.
Bonus symbol
The Bonus symbol sparks free drops. Landing 3 of these gives you 10 free drops. Multipliers built in the base game also carry over and remain active throughout the Bonus. The round runs until the drops run out or the 25,000x your bet jackpot hits. This path builds strain fast, as wins climb with no pause.
Big Symbols
Big Symbols drop in bold form, landing in 2x2, 3x3, or 4x4. They cover more spots, boosting cluster chances in one hit. Each acts as many small signs, linking easily with nearby matches. These links often trigger Avalanche chains that rush the grid.
Oxygen bonus rounds and free spins
Bonus features feel like a dive into a secret sea cave. Each free drop hums with previous wins. Chains and multipliers rise like a tide, thick with sharp edges. The sea holds its breath, then breaks in wild surge. Each retrigger pulls you deep, where bright wins wait in dark streams.
Bonus Game
The Bonus Game kicks in when 3 Bonus symbols appear, giving 10 free drops. Here, Multipliers from the base game roll over, then climb with each new drop.
They never reset; they simply stack and spike. This drive builds sharp runs, where each hit feels charged. More drops can land mid-game, pushing the streak higher.
This feature also offers the following rewards:
| Number of Bonus symbols | Reward |
| 2 Bonus symbols | +3 drops |
| 3 Bonus symbols | +5 drops |
Super Bonus
The Super Bonus levels up the base round to a new ground. One Multiplier, like the Collector or Dealer, stays active throughout the round. This locks steady growth, with each drop feeding more Avalanches.
You start with 10 free drops, but retriggers can spark with 2 or 3 Bonus symbols. With this persistence, even small chains can swell into huge wins.
Avalanche
Each round runs on the Avalanche drive, peaking during Bonus rounds. Wins clear out, and new symbols drop to fill gaps. The loop keeps rolling as long as new clusters form.
One free drop can burst into a chain of hits. Each strike also boosts the Multiplier on those spots, stacking higher with each fall. This pulse fuels Oxygen’s sharp blend of tight strain and blasting wins.
X-iter Buy Feature
Oxygen packs the X-iter Buy Feature, which grants fast entry to key features for a set price. Each mode holds a 94.00% RTP, and costs range from US$0.60 to US$2,000, tied to your bet size. This lets you choose to test quick runs or dive straight for the largest possible wins.
Here are the X-iter Buy Features to choose from:
| X-iter option | Cost | Reward |
| Bonus Hunt | 3x your bet | Boost bonus odds by over 3 times. |
| Multiplier Strike | 10x your bet | Add random Multipliers to the grid. |
| Persistent Multiplier | 25x your bet | Lock at least 1 Multiplier feature in place. |
| Bonus Game | 100x your bet | Buy direct entry into the standard Bonus. |
