Octo Attack

Octo Attack Slot Machine Review

Get wrapped up in the Octo Attack slot machine and win up to 10,000 times your bet. Otto the Octopus squirts ink and his tentacles can add extra wild symbols or multiplier wilds to the 6×4 grid. There are two free spins features where Otto is extra busy grabbing symbols for even more wins throughout.

A Mean Mollusc on the Streets

Unlike most aquatic animal games, Octo Attack online slot isn’t set underwater. The bright blue Octo has escaped and is roaming the grey streets of the city, finding dead fish, mushrooms and soda cans among the rubbish.

You’ll find a mix of colourful high value symbols alongside greyed out lightning bolts, speech bubbles and other unusual emblems. Bonus symbols in this desktop and mobile compatible online slot include the Eye of Otto, FS Scatters and W Wilds in a Gothic style. It’s a strange but effective mix from the studios of Hacksaw Gaming.

Match the Trash

This highly volatile game has a theoretical return to player of 96.27%. You can unleash Otto for between 0.10 and 100.00, with several bonus buy-in options available.

Unleash the Tentacles

All winning symbols disappear to trigger cascades of the remaining symbols on the Octo Attack slot machine reels and the cascades repeat until there are no more wins. All winning positions are marked with ink blotches and these build up over each series of cascades. When the Eye of Otto symbol lands, it triggers a Tenta-Grab mechanism that grabs a random symbol and places it in all the ink spots. This helps you grab extra wins, especially if he gets a Wild, Wild Multiplier or FS Bonus symbol.

The wilds can be regular versions that act as others when possible, or multipliers with random values of 1x – 10x that apply to any wins made with their help. Ink Spots disappear at the end of each Cascade sequence.

Get at least three Red FS Bonus Symbols on a base spin or via the Tenta-Grab feature and you get the same number of Eighth Arm is a Charm Free Spins as the triggering symbols. During this Octo Attack online slot bonus round, the ink stains don’t disappear and can keep multiplying until they are grabbed. This makes each Tenta-Grab feature even more valuable as multiple symbols are transformed.

Get three or more Yellow FS symbols to trigger the epic ‘Give me Eight’ Free Spins. Once again, ink spots remain in view until removed by the Tenta-Grab system, but now only Wilds or Multiplier Wilds will fill the ink spots. Get at least three FS symbols in any round and an extra spin is added to the total for even more chances to wrap Otto’s tentacles around big wins.

More Eight-Armed Creatures

You’ll encounter similar creatures in games like Beat the Beast: Kraken’s Lair slot machine from Thunderkick and Octopus Treasure slot game from Play’n GO at our recommended casinos.

Will Otto Have you in his Grasp?

The setting is unusual, but typical of the offbeat humour found in many Hacksaw Gaming slots. Play Octo Attack for free on this page at Slot Games to see how clusters of matching symbols trigger cascades and how Otto’s eye can see several symbol positions filled with a different type. When Wilds, Multiplier Wilds and FS Bonus Symbols fill the inky positions, the chances of a massive win increase dramatically.
