“Oxygen 2” by Elk Studios immerses players in a vibrant underwater realm filled with angular, stylized marine life and the remnants of a sunken vessel. The game unfolds on a 6×7 grid, employing a cluster-pays system with a dynamic “drop” mechanic, allowing for consecutive wins. The core gameplay revolves around an innovative multiplier system, featuring Oxygen Bubbles that can reach a staggering x2048 multiplier. Alongside, the Octopus and Jellyfish features add layers of multiplier action, creating an ecosystem of escalating win potential. “Oxygen 2” has a 94% RTP, offering a complex experience, the volatility is not specified in the data provided. Bonus features like the Bonus Game and Super Bonus Game, with persistent multipliers, enhance the depth of play. “Oxygen 2” offers a unique experience. The X-iter feature provides a shortcut to high-stakes action.
“Oxygen 2” is structured as a 6-column, 7-row slot that utilizes a cluster pays system. Winning combinations are formed by landing 5 or more matching symbols connected either horizontally or vertically. This system shifts the focus from traditional paylines to dynamic clusters, providing a more engaging and less predictable gaming experience. Once a winning cluster is formed, the Avalanche mechanic kicks in. The symbols involved in the win explode, making way for new symbols to drop down. This not only provides an opportunity for consecutive wins within a single spin but also interacts with other features, creating a fluid and potentially highly rewarding gameplay loop. One such interaction involves the Oxygen Bubbles. Every time a symbol explodes, it activates an Oxygen Bubble, and each subsequent explosion in that bubble's position doubles its multiplier value. These bubbles are persistent during the bonus game, and their values do not reset between free drops, leading to potentially massive multiplier accumulations.
The betting range in “Oxygen 2” is designed to accommodate both cautious players and high rollers. With a minimum bet of €0.20 and a maximum bet of €100.00, the game caters to a wide audience. The maximum total win in a game round is capped at 25,000x the placed bet. This high potential payout is particularly attractive to experienced players looking for significant returns. The game round automatically concludes when this win cap is reached, ensuring that the game remains balanced while still offering the thrill of a substantial win. Each bet is made with 100 coins, which adds a familiar, yet streamlined feel to the betting process. Oxygen Bubbles are not affected by gravity, adding a strategic element to how players approach each spin. Players are tasked with anticipating the movements of the symbols and the activation of the Oxygen Bubbles, creating a gameplay experience that is as much about strategy as it is about luck.
The Multiplier Strike feature adds another layer of excitement to the game. This feature can trigger at any symbol drop or free drop, placing a random amount of multipliers on the symbol grid. These multipliers can dramatically increase the payout of winning clusters, turning a standard win into a significant payout. The multipliers are a key component of the game's high volatility, offering the chance for substantial wins. As always in complex slots, it is critical to understand the intricacies of such bonus mechanics. If any of the features are not clear, you can always run the demo slot and refer to the built-in help by pressing the “i” button. You will find detailed explanations and clarifications there. The largest single multiplier that can appear in the game is 2048x, which showcases the potential for truly massive wins. The Jellyfish feature introduces another interesting element. One or more Jellyfish can arrive randomly, carrying multipliers. Each Jellyfish will stop at a random number of symbol positions, adding their carried multiplier to those positions. If a Jellyfish stops where there is already a multiplier, the existing multiplier is added to the Jellyfish multiplier, and the combined multiplier is then added to the existing multiplier, potentially leading to exponential growth in the multiplier value.
Special Symbols and Their Impact
“Oxygen 2” features a variety of special symbols that significantly impact the gameplay. The Wild symbol substitutes for any payout symbol, making it easier to form winning clusters. It pays as the highest payout symbol when part of a winning combination, enhancing the potential for big wins. Exploding Wilds activate an explode feature when part of a winning cluster, removing all payout symbols within two cone-shaped areas facing up and down or to the left and right from itself. This feature is triggered when no more winning combinations appear, and any Exploding Wilds and Blaster Wilds within the cone-shaped areas will be activated.
Super Exploding Wilds activate all unactivated oxygen bubbles behind the exploded symbols, adding another dimension to the wild symbol's impact. The Blaster Wild triggers when it is part of a winning cluster. It selects a random payout symbol or Wild symbol and replaces all payout symbols with the selected symbol in an X- or Plus-shaped pattern. Any Exploding Wilds or other Blaster Wilds along the pattern will be activated, and symbols affected by multiple Blaster Wild patterns will turn into Wild symbols. The combination of these special symbols creates a dynamic and unpredictable gameplay experience. Each spin has the potential to trigger a chain reaction of explosions, symbol replacements, and multiplier activations, making every moment of the game filled with anticipation and excitement.
In-Depth Look at Bonus Features
The Bonus Game in “Oxygen 2” is triggered when three Bonus symbols land on the reels. This awards players with 10 free drops. During the Bonus Game, multipliers are persistent between free drops, and the Octopus moves to a random position at the beginning of each free drop, increasing the chances of significant wins. If the Bonus Game is triggered with four Bonus symbols, it becomes a Super Bonus Game, during which the Jellyfish feature is triggered in every free drop, providing even more opportunities for multiplier accumulation. The Octopus in particular can significantly increase the win multiplier by adding a random selection of available multipliers to the winning cluster.
The X-iter feature allows players to buy into different game modes, providing a unique way to customize the gaming experience. For example, buying the Octo Strike guarantees an Octopus feature and at least one Multiplier Strike feature for 25x the selected bet. The Bonus option guarantees entry into the Bonus Game with an Octopus feature in each free drop for 100x the selected bet. Super Bonus guarantees entry into the Super Bonus Game with at least one Jellyfish feature and one Octopus feature in each free drop for 500x the selected bet. Additionally, the Special Wilds option guarantees at least three special wilds for 10x the selected bet, and the Bonus Hunt provides one game round with more than triple the chance to trigger the bonus game for 3x the selected bet. The minimum X-iter cost is €0.60, and the maximum is €50,000.00. X-iter purchases add a layer of strategy to the game, allowing players to choose their preferred way to engage with the bonus features.
