Oxygen 2 Slot Review

“Oxygen” is an engaging online slot game developed by ELK Studios, released on December 20, 2023.

Set in the vibrant depths of Coral Creek, this 6-reel, 7-row slot utilizes a cluster pays mechanism, offering players an immersive underwater adventure.

Game Overview

In “Oxygen,” wins are achieved by forming clusters of five or more matching symbols, either horizontally or vertically adjacent. The game features an avalanche mechanic, where winning symbols are removed, allowing new symbols to cascade into the empty spaces, potentially creating consecutive wins.

Symbols and Payouts

The symbols in “Oxygen” are divided into lower-paying and higher-paying categories:

Lower-Paying Symbols: Gemstones in green, orange, and purple. Achieving a cluster of 14 or more identical symbols awards between 10x to 20x the bet.

Higher-Paying Symbols: Green, orange, and purple fish, along with a gold scuba helmet. Clusters of 14 or more of these symbols yield payouts ranging from 25x to 100x the bet.

The golden treasure chest serves as the scatter symbol, while three distinct wilds can appear during gameplay:

Standard Wild: Substitutes for other paying symbols to help form winning combinations.

Exploding Wild: When part of a winning cluster, it removes all symbols within an X pattern above and below itself.

X-Blaster Wild: Randomly replaces all payout symbols within an X pattern with either wild symbols or random payout symbols.

Multiplier Features

A standout feature in “Oxygen” is the multiplier system:

Oxygen Bubbles: Each time a winning combination occurs, an oxygen bubble with a 1x multiplier appears in the position of the removed symbols. If another win happens in the same position, the multiplier doubles, potentially reaching up to 2,048x.

Collector Feature: When included in a winning cluster, it collects all multiplier values on the grid, enhancing the total win.

Dealer Feature: Multiplies the multiplier values in any V-shaped area adjacent to it, further boosting potential payouts.

Bonus Features

“Oxygen” offers enticing bonus features to elevate the gaming experience:

Bonus Game: Triggered by landing three scatter symbols, awarding 10 free spins. During this round, landing two or three additional scatter symbols grants 3 or 5 extra free spins, respectively.

Super Bonus: Activated by landing three scatter symbols simultaneously with a persistent multiplier, ensuring at least one multiplier feature remains persistent throughout the bonus game.

X-iter™ Feature: Allows players to directly access various game modes, including the Bonus Game and Super Bonus, for a specific cost, providing immediate entry into the action.

Betting Range and RTP

The game accommodates a wide range of players with a betting range from €0.20 to €100 per spin. It has a high volatility level, offering the potential for substantial wins, with a maximum payout of up to 25,000x the bet. However, the Return to Player (RTP) rate is 94%, which is slightly below the industry average.

Conclusion

“Oxygen” by ELK Studios delivers a captivating underwater-themed slot experience, combining innovative features like persistent multipliers and various wilds with dynamic gameplay. Despite its lower RTP, the game’s high volatility and substantial maximum win potential make it an appealing choice for players seeking thrilling and rewarding slot sessions.
