In the silent depths of Coral Creek lies a scattered vision of the future that somehow slipped into the past. As sea creatures tinker with the glowing relics, the ruins whisper the remains of a forgotten advanced civilization, or a future city lost to time itself. Oxygen 3 is a 6 column, 7 row submerged slot that comes with multipliers, special wilds, symbol removal, a bonus, and a super bonus, all packed into a potential of 25,000x bet.

Winning symbols are removed from the grid, causing remaining symbols to drop and new ones to fall in, potentially creating consecutive wins within a single round.
One or more clusters of Oxygen Bubbles with multipliers are placed in random positions of the grid at the start of a spin or after any symbol drop.
A Clam Wild symbol triggers one of three modifiers when part of a winning cluster: Pearl (redrop with one random symbol type), Squid (generates Wilds while moving), or Starfish (removes symbols, increases multiplier values, becomes Wild).
A special Wild that detonates adjacent positions on the grid, removing symbols and triggering a cascade.
A special Wild that removes all symbols in its path across the grid, clearing the way for new symbols to cascade in.
Triggered by landing three Bonus symbols. Features an Oxygen Meter that fills with each win; when full, it upgrades a cluster of multipliers on the grid.
An enhanced version of the Bonus Game triggered by landing one Super Bonus symbol alongside two regular Bonus symbols. Fills meters faster and selects more multipliers.
Feature buy menu offering 5 game modes: Bonus Hunt (2.5x bet), Multiplier Strike (10x bet), Persistent Multiplier (25x bet), Free Spins (100x bet), and Super Bonus (250x bet).
Symbol positions accumulate multipliers that double with each win on that position, increasing payout potential.
ELK Studios does not publish a standalone demo of Oxygen 3 — their games only run inside a casino's own client, so there is nothing we can host here. Where a studio does publish one, we run it on the slot's page with virtual credits.
