Rules and Gameplay

Dive into the deep with ELK Studios’ Oxygen slot, a game that merges aquatic allure with exciting mechanics. Played on a 6×7 grid, the game uses a cluster pays system, where players form wins with 5 or more adjacent symbols. The Avalanche feature adds dynamism, as winning clusters disappear to make way for new symbols, potentially creating chain reactions of wins. Bets range from $0.20 to $100, catering to various budgets. Oxygen’s medium to high volatility and its unique gameplay offers an engrossing experience, blending frequent wins with the chance for substantial payouts.

Bonus Features

Oxygen’s gameplay is enriched with a treasure trove of bonus features:

  • Avalanche Feature: Wins trigger cascades of new symbols for extended winning opportunities.
  • Special Wilds: Exploding and X-Blaster Wilds offer unique benefits, enhancing winning possibilities.
  • Progressive Multipliers: Each win increases multipliers on winning spots, potentially reaching up to x2,048.
  • Random Multiplier Enhancements: Features like The Multiplier Strike and The Collector add an extra layer of excitement.
  • Free Spins Rounds: Standard and Super Free Spins modes, each with persistent multipliers, elevate the thrill.
  • X-iter Feature: Allows players to buy into bonus rounds, available in selected regions.


The Oxygen slot features a vibrant array of symbols reflecting its subsea theme:

  • Aquatic Creatures: Octopus in Diving Helmet, and various colored Fish symbols, each carrying different values.
  • Colored Stones: Serve as lower-paying symbols but are crucial for consistent wins.
  • Wild and Scatter Symbols: Essential for triggering bonus features and substituting pay symbols.
