The premier casino game supplier, Hacksaw Gaming, has released its latest online slot, Octo Attack. The set stars a captivating octopus named Otto that resides in a domain far from ordinary. The 6x5 slot is odd and miscellaneous in every aspect, from the visuals to the bonus features. With it, the software developer displays its ability to weave together seemingly random elements into one coherent piece capable of winnings up to 10,000x the bet.

Key Takeaways
- Octo Attack features Otto the Octopus as the main character
- It has a massive payout potential of up to 10,000x
- The game has a 96.27% RTP and medium volatility math model
Monochrome World of Trash
Hacksaw Gaming brings Otto to life in a seemingly depressing world abundant with waste and a monochrome shade. The blue eight-legged chap is hard to miss as he oversees gameplay standing beside the 6x5 matrix. Hacksaw Gaming adds its usual layer of punk-inspired pop-art style to the symbols, creating something visually cool and unique.
Base Game Payouts
While Otto seems angry, he is not all frowns and sadness as he cooks up symbol payouts. Landing five or more symbols of a kind vertically or horizontally triggers a winning cluster. The monochrome symbols are Otto Attack’s low pays, while the colored ones are the premiums. The most valuable clusters are for 26 or more symbols, and they pay 100 to 500 times the stake.
With a rated variance of 3/5, Octo Attack has a medium volatility. The math model also features a 96.27% RTP rate, slightly above the standard. This is the hypothetical return value when staking between $0.10 and $100 per round.
A Clever Lot of Bonuses
The bonus features account for the best Octo Attack Slot has to offer. Wild symbols, which can complete other symbols’ payout combinations, award a multiplier of up to 10x to boost potential wins. Symbols in paying combos vanish from the grid, and their spots are marked with ink stains as they accommodate new icons. These stains are critical in the Tenta-Grab Mechanic and come off between base game rounds.
Beyond the wild icons, Otto is instrumental with the Eye of Otto symbol, which triggers the Tenta-Grab mechanic. This feature selects one random symbol and places it on all ink-stained positions, potentially forming new winning combos. The mechanic can choose any character, whether it’s low-value, high-value, or wild.
Otto Attack also has a free spins bonus dubbed Eight Arm Is The Charm. Ink stains are not removed from the grid between these spins until the Tenta-Grab Mechanic activates. The slot awards even bigger wins in the Give Me Eight! bonus triggered by three epic FS symbols. A Bonus Buy option is available for gamblers who want to jump straight into the free spin action.
