Octo Attack™ Slot Review
Get wrapped up in the Octo Attack™ slot machine to win up to 10,000x your bet. Otto the Octopus squirts ink and his tentacles can add extra wild symbols, or multiplier wilds to the 6x4 grid. There’s two free games features where Otto is extra busy grabbing symbols for even more wins throughout.
A Mean Mollusc on the Streets
Unlike most games starring aquatic animals, the Octo Attack™ online slot isn’t set underwater. The bright blue Otto has escaped and prowls the grey streets of the city, where he finds dead fish, mushrooms, and soda cans among the trash.
You’ll find a mix of colourful high value symbols alongside greyed-out lightning bolts, speech bubbles, and other unusual emblems. Bonus symbols from this desktop and mobile compatible online slot include the eye of Otto, FS scatters, and W wilds in a Gothic style. It’s a weird but effective mix from the studios of Hacksaw Gaming.
Match the Trash
This high volatility game has a theoretical return to players of 96.27%. You can unleash Otto for between 0.10 and 100.00 with several Bonus Buy options available. It’s a cluster pays game where you win the following multiples of the bet from the various symbols –
Unleash the Tentacles
Any symbols in a win vanish to trigger cascades of those left on the Octo Attack™ slot machine reels and cascades repeat until there are no new wins.
All winning positions get marked by ink stains and these build over any series of cascades. If the eye of Otto symbol lands, it awards a Tenta-Grab mechanic, grabbing a random symbol and placing it in all ink-stained spots. That helps you grab extra wins, especially if he gets hold of a wild symbol, wild multiplier, or FS bonus symbols.
The wilds can be regular versions that act as others when possible, or multipliers with random values of 1x – 10x that then applies to any win made with their help. Ink stains disappear at the end of any cascades sequence.
Land at least three red FS bonus symbols in a base spin, or via the Tenta-Grab feature and you get the same number of ‘Eighth Arm is a Charm’ free spins as triggering symbols. During this Octo Attack™ online slot bonus round ink stains don’t vanish and can build in number throughout until grabbed. That makes any Tenta-Grab feature even more valuable as multiple symbols transform.
If three or more yellow FS symbols appear, they award Epic ‘Give me Eight’ free spins. Once again, ink stains remain in view until taken away by the Tenta-grab system, but now, only wilds or multiplier wilds will fill the inky spots.
Land at least three FS symbols in either round to get an extra spin 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 such as the Beat the Beast: Kraken’s Lair slot machine by Thunderkick and the 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 off-beat humor found in many Hacksaw Gaming slots. Play Octo Attack™ for free on this page of VegasSlotsOnline to see how clusters of matched symbols trigger cascades, and how the eye of Otto can see multiple symbol positions fill with another type. If wilds, multiplier wilds, of FS bonus symbols fill the inky positions the odds of a massive win increase dramatically.
Once you know how everything works, play the Octo Attack™ slot online at our favorite casinos and enjoy the gripping gameplay for real.
