No-Deposit Free Spins for Octo Attack
Gameplay
It is based on cluster pays, where landing 5 or more matching symbols adjacent to each other vertically or horizontally forms a winning cluster. The game offers medium volatility with an RTP of 96.27%, making it suitable for casual players as well as those chasing bigger wins. Bets range from $0.10 to CA$100 per spin, and as clusters form, the winning symbols disappear, making way for cascading new symbols. The game also introduces Ink Stains, an exciting mechanic that holds potential for even more wins as part of the Tenta-Grab feature, which we'll explore in detail.

Slot Features
Ink Stains & Tenta-Grab Mechanic
After a winning combination, the grid marks the winning positions with Ink Stains. These stains remain until they are used by the Tenta-Grab mechanic, which is triggered by landing the Eye of Otto symbol. The Tenta-Grab selects one random symbol from the grid and replaces all Ink Stains with that symbol, leading to more potential wins. It can grab regular symbols, wilds, or even wild multipliers, adding an extra level of excitement to every spin.
Eighth Arm Is The Charm
Landing at least 3 regular free spin (FS) symbols triggers the Eighth Arm Is The Charm feature, awarding free spins equal to the number of FS symbols landed. During this bonus round, Ink Stains do not reset between spins, which increases the chances of triggering the Tenta-Grab mechanic for even bigger wins.
Give Me Eight!
Trigger the Give Me Eight! feature by landing 3 or more epic FS symbols. This round plays similarly to the Eighth Arm feature, but the Tenta-Grab mechanic here only targets wilds or wild multipliers, increasing the potential for massive payouts. Just like in the previous feature, landing additional FS symbols during this round rewards extra spins.
Bonus Buy
Players have the option to buy into different bonus features for a cost:
- BonusHunt FeatureSpins: 5x higher chance of triggering a bonus for 3x the bet.
- Tentacular FeatureSpins: Guarantees at least 1 win and 1 Eye of Otto symbol per spin for 50x the bet.
- Eighth Arm Is The Charm: Costs 100x the bet to enter the regular free spins round.
- Give Me Eight: 300x the bet to trigger the epic FS round with guaranteed wilds or wild multipliers.
