How To Play Octo Attack Mobile Slot
The Hacksaw Gaming Octo Attack slot transports players into a world where eight-legged invaders overrun Earth. But don’t worry; these creatures, led by the quirky Otto the Octopus, are more than happy to hand out bonuses and rewards.
Despite the gloomy backdrop of a trash-ridden, monochrome city, Otto has a knack for brightening up the reels with exciting features, including Multiplier Wilds and Tenta-Grab Free Spins, giving you a shot at winning up to 10,000x your bet.
Developed by Hacksaw Gaming, this unique mobile slot blends an alien invasion theme with exciting mechanics that can lead to substantial wins. With a 6-reel, 7-row setup and cluster pays, Octo Attack offers a thrilling ride, especially for players seeking mid-level volatility and engaging bonus features.
A Unique Visual Style with Engaging Gameplay
The game’s visuals set it apart, with a monochrome city in the background, where Otto accompanies you by the reels. Although most symbols are in black and white, some, like Otto and the higher-paying trash symbols, burst into colour, not unlike the Cash Crew slot.
The contrast gives the slot a distinct aesthetic, and despite the near-dreary environment, the gameplay is anything but dull. Wins are made by landing clusters of 5 or more matching symbols and features like Multiplier Wilds, Free Spins, and Otto’s Tenta-Grab ability keep things exciting.
In terms of gameplay, the base game alone offers plenty of action with its cascading reels and cluster payouts, but it’s the free spins and special bonuses where Octo Attack online slot truly shines.
Octo Attack Bonus Features Explained
At its core, Octo Attack revolves around its Multiplier Wilds. These wilds don’t just substitute for other symbols; they land with multipliers between 1x and 10x, giving players the potential to hit big wins. Winning clusters leave behind Ink Stains on the reels, marking the positions of previous wins, with new symbols cascading down to fill the gaps.
The ink stays in place until Otto’s Tenta-Grab feature is triggered, which can turn these stained positions into something much more valuable thanks to the game’s most thrilling mechanics: the Tenta-Grab. When an Eye of Otto symbol lands on an Ink Stain, Otto’s tentacle swoops in, grabbing a random symbol from the grid and replicating it across all Ink Stain positions.
This feature can quickly fill the screen with valuable symbols, delivering substantial payouts, similar to the Coba mobile slot’s spreading symbols.
Free Spins: Eight Arm Is the Charm & Give Me Eight
There are two main Free Spins features in the Octo Attack slot online.
First, the Eight Arm Is the Charm free spins are triggered by landing 3 or more scatter symbols. The number of initial spins matches the number of triggering scatters, and what sets this mode apart is that Ink Stains remain on the reels until the Tenta-Grab feature activates, giving you more chances for big wins.
The second free spin mode, Give Me Eight!, is activated by three or more Epic Scatter symbols. In this mode, Tenta-Grab only grabs Wild and Wild Multiplier symbols, pushing the volatility and win potential to the max. Ink Stains remain until Otto’s tentacles have had their fill, ensuring you get the most out of each free spin round.
The Octo Attack slot offers several feature buy options if you’re itching to jump straight into the action. You can purchase entry into the various bonus rounds, including the Eight Arm Is the Charm and Give Me Eight! free spins and other feature spins, such as Tentacular FeatureSpins, for a price of up to 300x your bet.
It’s expensive and not for the faint of heart, but a feature in other Hacksaw games such as Orb of Destiny or Chaos Crew 2.
Who Will Enjoy Octo Attack?
Octo Attack is ideal for players who enjoy medium-volatility slots with an unconventional theme.
The game’s unique visuals, paired with exciting features like the Tenta-Grab and Free Spins modes, offer plenty of opportunities for big wins, particularly for those who enjoy features always in play, even in the base game.
However, the monochrome art style might not appeal to everyone, especially those who prefer vibrant and colourful slots. But if you appreciate innovative design and mechanics, this online slot will keep you entertained as you aim for that Octo Attack max win of 10,000x your bet.
