Octo Attack Demo & Review

Octo Attack review

Octo Attack features Otto the Octopus and his Tenta-Grab mechanic. Winning symbols disappear and new ones drop in, but each winning position is marked with an Ink Stain. When the Eye of Otto lands on a grid with ink stains, he grabs one random symbol and copies it into every stained position, and his own.

Wilds can carry additive multipliers of 1x to 10x, so a grab that copies a wild across all the stains is the best result. Stains reset between spins, so the cascade itself is what builds the setup. The cap is 10,000x.
