Oxygen in Demo Mode

The Oxygen slot machine is a 2023 game powered by ELK Studios. Its central theme is a deep sea and multiple underwater creatures living in it. Some are cute, like seahorses, while others are quite creepy.

The game’s paylines differ from those you can experience in classic titles. Instead, this 6-reel, 7-row slot supports the Cluster Pay option and the Avalanche mechanic. Bets range from $0.20 to $100, while the maximum win is x25,000 the bet per round. The game’s volatility varies from medium to high (7 out of 10 on the provider’s scale). The RTP is low for a modern game, reaching 94%. Despite the lower RTP, the Oxygen slot machine promises an exhilarating journey into the deep sea, making it a captivating choice for those seeking thrilling and fun slot games.

The game has multiple features to make your gameplay interesting, including three types of Multipliers, Wild Widifiers, five Oxygen Bonus Buy features and more.

The game supports a free demo mode and entertaining Cascading and Avalanche mechanics. To win, you must collect at least five matching symbols on the slot’s grid (anywhere). They may be located both vertically or horizontally.

After Oxygen symbols are removed, their places are boosted with bubble multipliers. If you keep winning, these multipliers double with every other successful spin. Below, you can check available symbols and their values.

There are plenty of Oxygen features and bonus options you can experience while playing the game. Learn more about what each of them can bring you.

• Big symbols — these are the same symbols described in the paytable, which land randomly and occupy a 4x4 place on the grid.

• Wilds — you may trigger 2 types of Wilds in this game: Exploding (clear the space around) and X-Blaster (removes symbols in the X-shape).

• Doubling Position Multipliers — trigger this feature to boost the position by x1. Further, it doubles per win and may reach up to x2,048 the bet.

• Multiplier — along with the previous option, Oxygen offers 3 more Multipliers. Among them are the following: Collector (absorb all multipliers in view) and Dealer (increase multipliers by at least x2 in the V-shape). Also, the Oxygen free slot offers the Multiplier Strike that brings a random number of multipliers at the end of Avalanche.

• Free Spins — collect 3 scatters to get 10 free spins in the bonus game.

• Super Free Spins — after landing at least 3 Scatters, you receive a persistent Multiplier feature and non-resetting Multiplier positions. If you land 2 or 3 Scatters, you can get 3 or 4 extra free spins.

• Bonus Buy — if you decide not to wait for bonuses, you can simply pay for them. There are 5 options available, including Bonus Hunt (x3 your bet), Multiplier Strike (x10 your wager), Persistent Multiplier (x25 initial bet), and Bonus Round (x100 initial stake). A high roller may take a risk and pay x500 initial bet to get a Super Bonus Round.

The Oxygen demo slot offers a bet range from $0.20 to $100, while the maximum payout to expect is fairly high (x25,000). A low RTP of 94% may be a real deal breaker for some players since it decreases the odds of winning. However, it is a trend for recent ELK Studios games.

To plunge into the world of underwater adventures, you need to take the following steps.

1. Run the game slot.

2. Set the bet limit (click on the “Bet” button in the lower-left corner of the screen).

3. Trigger the spin button and play for fun!

Do not forget to check available features and symbol values before playing. It will help you better adapt to the gameplay.

Autoplay Mode

The slot also supports an Autoplay option, so you do not need to trigger the spin button every time. Simply click and hold the spin button, select from a predetermined number of auto spins (10, 25, 50, or 100), and play for fun!

To prepare this Oxygen slot review, I played it in a demo mode and made 100 spins with the $1 bet. I was pleasantly surprised by hitting 4 wins in a row from 4th to 7th spins made. What’s more, the 3 others were Wilds.

The overall number of Wilds (regular and Exploding) was 12. Among other special features I received were 1 Super Bonus and 1 Collector. Most winnings were average (from $0.20 to $0.70), but then I was excited to get a Big Win of $22.1 on the 79th spin.

All in all, I won 34 rounds, so the slot’s hit frequency is 34%. It is a good result, given the hit frequency of other popular ELK Studio games, such as Visitors (22.6%) or Pirots (26.8%). I started with $1,000 on balance and ended with $992.25. Thus, you should not expect super big wins in case you are ready to use the Bonus Buy option or have a significant budget.
