Octo Attack Slot RTP, Details & Wager Limits
When playing the Octo Attack slot, the first thing you’ll spot is the reels. It’s a 6×5 grid, which is larger than most slot games. Instead of paylines, it uses cluster pays. If you land at least five symbols as a cluster, then it creates a win. I enjoy cluster pay games, so it was a nice introduction to the Octo Attack demo.
The Octo Attack game has a stake range of 10p to £100, which is attractive for many online slots players. I liked the stake controls while creating my Octo Attack review. They’re above and below the spin button, so they’re easy to use. You can set up an autoplay and use turbo spins, but you can’t use the features at UK online casinos.
The Octo Attack RTP is 96.27%. While it’s pretty much in line with the best RTP slots, there are RTP ranges, which can drop down to 88%. You must find the best possible RTP level to give yourself the best chance of success. Octo Attack has a medium volatility, which I found surprising due to the significant maximum win.
You can grab an Octo Attack max win of up to 10,000x your stake. It’s an excellent payout, particularly when taking the volatility into account. The free demo slots version shows that the free spins round is the best way to claim the top payouts. During the demo, I managed over 900x my stake more than once, and that was during the Give Me Eight free spins.
Theme – Amazing Underwater Action
The graphics in Octo Attack are excellent. Everything has a fun cartoon style, which fits with the underwater theme. Hacksaw Gaming has done a fantastic job creating something new and fresh. All of the symbols link to the theme, even dispensing the typical playing card symbols for something relating to underwater action.
The sound is some of the best you’ll hear at online slot sites, helping to create an engaging atmosphere. It’s a sinister soundtrack that has an electro feel, which matches the look of the titular octopus. It’s great to see something different happening because many creators stick to generic sounds.
The colours are extremely intriguing. When you first load up Octo Attack casinos, you will notice how Hacksaw Gaming juxtaposes bright and dark tones. The background is extremely dark, which ensures the bright colours stand out more on the reels. It’s a clever way to ensure things stand out without going over the top.

Octo Attack Mobile
The Octo Attack mobile slot retains a lot of the desktop’s aesthetics. The images all retain clarity, showing off the design choices of Hacksaw gaming. The controls move to the bottom of the screen, but it’s still easily accessible. Overall, it’s an excellent transition from desktop, making it one of the best online slots at a mobile casino.
Octo Attack Bonus Features
There are plenty of Octo Attack bonus features available. They range from the base game to the bonus rounds, with the potential of the features improving when the bonus begins. The wild symbols in Octo Attack help to create extra wins, but they can have multipliers attached, increasing payouts.
Cascading Reels
The cascading reels in Octo Attack are a fun feature. They work the same way as other games with this mechanic, winning spins remove the paying symbols, with new ones falling into place. They can potentially create new wins when they land, which continues the process.
However, because Octo Attack uses cluster pays, there are lots of ways to create a win. Not quite as many as Megaways slots, but still a lot of potential winning spins. It also adds ink blots for the duration of the cascade; they vanish on the next new spin. These are useful for the next feature.
Tenta-Grab
When the Eye of Otto scatter symbol lands, it triggers the Tenta-Grab feature. This chooses a random symbol and then replaces all ink blots with it. If you’ve created lots of wins during your cascade, there’s the potential for significant wins with this feature. It only triggers when your cascades have finished, so there are plenty of chances to increase the number of ink blots.
Eight Arm Is the Charm Free Spins
This round begins when you land at least three standard scatters on the reels. You get the same number of spins as scatters you land, so there’s the potential for up to 30 spins here. Whenever three scatters land during the round, you get three extra spins. Additionally, ink blots remain on the screen until the Tenta-Grab claims them.
Give Me Eight Free Spins
Similarly to the other free spins round, whenever three ultra scatters land, the round begins. You get the same number of spins as scatters, so up to 30 are available again. If you land three scatters, it awards an extra spin, as in the previous feature. So, what’s the difference, and what makes it ultra? This time, the ink blots remain in place, but when the Tenta-Grab gets them, it guarantees wilds, multiplier wilds, or free spin scatters. As a result, it makes it a much more generous round.
Bonus Buy (Not Available in the UK)
Non-UK players can activate the bonus buy feature by clicking the Buy Bonus button on the main game. You will have access to the Feature Spins buy option, with each spin guaranteeing different features. Each Feature Spin remains active until you click the Disable button.
Octo Attack Verdict: Have Fun Underwater with Octo Attack
The range of bonus features here ensures it’s an exciting experience. You won’t be bored at any point because there’s always something ready to happen. The fantastic visuals and sounds just add to the enjoyment of the game. It’s a testament to how much work Hacksaw Gaming has put in.
The maximum payout here is incredible. A 10,000x your stake win is good at the best of times, but with medium volatility, it makes it even more impressive. It ensures that Octo Attack isn’t style over substance; it’s a slot with plenty to offer. It’s one of the best on the market, and it’s well worth trying out.
