Octo Attack Online

In 2024, Hacksaw Gaming delighted its fans with a new release: the Octo Attack slot machine. This slot features a group win collection system, a wide range of bonuses, an original design, and a unique Tenta-Grab system. This new product perfectly embodies the Hacksaw style.

Octo Attack features medium volatility and an RTP of 94.26%, offering an optimal balance between frequency and payout size. This slot also offers significant potential: the maximum win is 10,000x your stake. More details in my review.

Gameplay and symbols

Octo Attack perfectly embodies the developer’s style. You’ll discover a new monochrome world, inspired by public art and the post-apocalyptic era, with Otto, an octopus, as the main character. This malevolent octopus doesn’t just observe the game; he participates and interacts with the game board. The combination of monochrome tones and bright elements creates a unique, albeit slightly dark, atmosphere.

Before the game starts and before each new spin, you can choose a bet from $0.10 to $100 per spin. This bet will influence the amount of winnings, as well as the cost of activating bonuses. The slot machine uses a clustering system to collect winnings. There are no paylines; you win for a group of 5 or more identical symbols. Symbols can be placed anywhere on the game board, but must be touching horizontally or vertically.

High-paying symbols are represented by colorful images of sharks, mushrooms, fish, etc. They offer large payouts, but rarely form combinations.

The low-paying symbols are monochrome, which enhances the overall design of the slot machine. They often form winning combinations, but only pay out a portion of the stake. However, large groups can generate significant wins.

Features and bonuses

The bonuses on the Octo Attack slot machine are interesting and profitable.

Cascading rollers

Winning symbols are removed from the game board and replaced with new ones, allowing you to form new groups in a single turn.

Wild

The Wild symbol substitutes for all other symbols on the paytable and helps to create more winning combinations. Furthermore, it can award a random multiplier from x1 to x10, thus increasing winnings.

Ink Stains

A spot appears under the winning symbols, which activates the Tenta-Grab mechanic if you manage to collect another group in those cells. The spots disappear if you don’t win again.

Eye of Otto + Tenta‑Grab mechanics

Otto’s eye appears on the cell with inkblots. It copies a random symbol onto all cells with inkblots, forming a large group. If a Wild or a Wild with a multiplier is copied, it also spreads to other cells.

Free Tours

The free spins round is triggered by Scatter symbols. The unique feature is that there are two types of bonus symbols: “Eighth Arm Is The Charm” and “Give Me Eight!”. Each symbol triggers a free spins round with unique features:

Eighth Arm Is The Charm – 3 classic Scatters award as many free spins as there are Scatters + Inkblots on the board. New Scatters award +1 extra spin for every 3 symbols.

Give Me Eight! – 3 Epic Scatters trigger free spins, while Tenta-Grab brings in numerous Wilds with multipliers. Thanks to the large number of Wilds, you can achieve much bigger wins. You get +1 spin for every 3 new Epic Scatters.

Bonus purchase function

The slot machine allows you to activate bonus features in exchange for money. You can activate the following features:

• Bonus Hunt – costs 3 times the stake, increases the frequency of Scatter symbols;
• Tentacular Featurespins – costs 50 times the stake, guarantees an Eye Of Otto;
• Eighth Arm – costs 100 times the stake, instantly activates the usual free spins;
• Give Me Eight! – costs 300 times the stake, triggers the epic version of the bonus round.

Conclusion

Octo Attack is an excellent choice for fans of slot machines with unique mechanics and a dark atmosphere. The winning potential is considerable: you can win big by activating the bonus features. The activation rates are high, making the game more than just entertaining.
