Before starting your gameplay, players can select their bet amount between a minimum of 0.2 and a maximum of 100. The game has a default Return to Player (RTP) of 96.00%, which provides stable long-term returns, and operates on a medium-high volatility model that favors high wins, albeit less frequently. Players can achieve wins up to 25,000x the bet in any single round, with the base game hit frequency set at 33%.

<pIn Oxygen 3, players will journey into vibrant waters to unearth treasures lost to time. The environment showcases an astonishing view with lush landscapes and towering ruins suggesting a civilization submerged due to environmental calamities. The colorful coral formations have started to meld with the remnants of human architecture, creating a unique landscape. This captivating imagery is enhanced by striking graphics, providing an ultra-modern experience across all devices, including desktops, smartphones, and tablets.

To win in Oxygen 3, players must connect at least 5 matching symbols in adjacent horizontal or vertical clusters. The low-paying symbols consist of three types of coral—blue, green, and pink—which award between 20x to 40x the bet for a cluster of 32 or more matching symbols. The high-paying symbols feature blue, green, and pink fish, which offer payouts between 60x to 150x the bet for clusters of 32 or more. The top symbol is an octopus, rewarding 250x the bet for 32 symbols. Additional features include Clams that activate special mechanics, three varieties of Wilds, and Bonus symbols represented by a futuristic treasure chest.

What features are available in the slot Oxygen 3?

The game includes features such as Avalanche, Big Symbols, Multipliers, Multiplier Strike, Clam Features, Wilds, Bonus & Super Bonus Game, and Feature Buy (X-iter).

Avalanche

The Avalanche feature allows for multiple consecutive wins within a single game round. When a winning combination occurs, the symbols involved are removed from the grid, making room for new symbols to fall into place, potentially leading to additional victories until no new combinations are formed.

Big Symbols

Any paying symbol can appear in a larger format, ranging from sizes of 2×2, 3×3, or 4×4. Big Symbols are calculated based on the total number of individual symbols they represent.

Multipliers

When a winning combination is formed, the involved positions will be marked with Oxygen Bubbles. The next time a highlighted cell contributes to a win, it receives a multiplier of x2. Every subsequent win involving that position doubles its multiplier value, and if several positions are affected, their multipliers combine for the payout. These multipliers remain active during the Avalanche sequence but are reset before the next paid spin in the base game.

Multiplier Strike

This feature can activate at the beginning of a spin or after any symbol drop, placing one or more clusters of Oxygen Bubbles equipped with multipliers in random locations on the grid.

Clam Features

A Clam symbol acts as a Wild that can appear anywhere on the grid. When it participates in a winning cluster, it triggers one of three modifiers:

Pearl = triggers a redrop with a random symbol type and any feature symbols locked in place. The process continues as long as either the selected random symbols or Wilds keep landing.

Squid = moves to random positions, generating additional Wilds.

Starfish = removes symbols in a random direction while adding a multiplier to the last affected position. The sequence continues until the Starfish transforms into a Wild.

Wilds

Oxygen 3 features three types of Wilds: Regular Wilds that replace standard symbols, Exploding Wilds that eliminate symbols in a cone shape, and Blaster Wilds that turn surrounding symbols into matching symbols in a plus or X shape. Symbols transformed for a second time become Wilds.

Bonus & Super Bonus Game

Landing 3 Bonus symbols on the grid initiates the regular Bonus Game. If one of the symbols is a Super Bonus, a premium version of the game is activated. During both modes, multipliers from Oxygen Bubbles carry over between spins. An Oxygen Meter charges with each winning combination, and when full, it triggers and enhances a cluster of multipliers on the grid. The Super Bonus Game upgrades cover a larger area.

Feature Buy (X-iter)

As with many of ELK Studios’ titles, Oxygen 3 includes the X-iter menu with options to activate features and bonuses at set prices that correspond with your active stakes:

2.5x = Bonus Hunt, offering a 3-fold increase in the chances of triggering the Bonus Game.

5x = Mega Hunt, providing a 6-fold increase in the chances of triggering the Bonus Game.

25x = Clam Chowder, ensuring 3 Clam symbols.

100x = Regular Bonus Game.

250x = Super Bonus Game.

Final Thoughts on Oxygen 3

The position multiplier mechanism has gained popularity since its introduction in Sugar Rush by Pragmatic Play in 2022 and continues to be a prevalent feature into 2026. ELK Studios delves into the ocean depths with Oxygen 3, enhancing the gameplay with cluster wins powered by oxygen bubbles. The series has evolved, starting from a fundamental game model and incorporating features such as Multiplier Strike, Blaster Wilds, and Exploding Wilds, while introducing Clams with impactful modifiers. The new features like Pearls, Squids, and Starfish offer engaging mechanics that frequently enhance gameplay. The additional Wilds, sticky respins, and increasing multipliers play a vital role in the experience, especially in the Bonus Game variants, which focus on clusters and boost multipliers in surrounding positions. With a return to a default RTP of 96%, this installment stands strong within the series.

Visually, the game maintains the vibrant and polished aesthetic of its predecessors while progressing the story of Coral Creek into a more futuristic realm. While it may not seem drastically different from its predecessor, it consistently presents a captivating underwater tale with subtle innovations.

Oxygen 3 effectively expands the feature lineup, emphasizing core gameplay elements and offering an engaging experience for players.
