Hold your breath — Otto the Octopus isn’t letting go that easily. Octo Attack by Hacksaw Gaming is a quirky, underwater slot where trash and treasure swirl together in a gritty cartoon reef. With 6 reels, 5 rows, and cluster pays in place of paylines, this game packs plenty of surprises. And with wins of up to 10,000x your stake, things can get deep fast.
Escaping Otto’s tentacled grasp is simple — at first. Choose your stake, hit the spin button, and watch as clusters of matching symbols form to trigger wins. Octo Attack uses a cluster pays system instead of traditional paylines, so any group of adjacent matching symbols counts as a win. Symbol clusters vanish after a win, making way for new ones to drop in — and that’s when things really start to snowball.
Octo Attack blends quirky cartoon vibes with a post-apocalyptic sea world. Think: eerie aquariums, rogue marine life, and a defiant octopus running the show. Otto’s not just the mascot — he’s the menace in this darkly playful underwater escapade. The visuals lean into grungy, comic-style animation with bold character designs and splashes of ink every time a win triggers. It’s unique, immersive, and dripping with personality.
The ocean is full of surprises, and Octo Attack brings some inventive bonus features to the surface:
Bonus Hunt FeatureSpins – Costs 3x your bet. A light teaser with increased chances of bonus activation.
Tentacular FeatureSpins – Costs 50x your bet. Cranks up the chaos with more frequent tentacle-triggering features.
Eighth Arm is the Charm – Costs 100x your bet. Jump straight into the standard free spins round.
Give Me Eight – Costs 300x your bet. Dive right into the highest-volatility mode with epic wild-focused free spins.
