“Octo Attack” transports players to an Earth under invasion by octopus creatures. The protagonist, a friendly octopus named Otto, generously distributes bonuses and special features throughout the game. Despite the game’s somber atmosphere with abundant debris and monochrome colors, Otto has prepared several engaging functions that brighten the reels with multipliers and wild symbols, offering players opportunities to win up to 10,000 times their stake.
“Octo Attack” is a video slot featuring 6 reels and 7 rows that utilizes the Cluster Pays mechanism, requiring 5 or more identical symbols to form winning combinations. Players can place bets ranging from 0.1 to 100. The game offers medium volatility with an RTP of 96.27%. The maximum potential win reaches an impressive 10,000 times the stake.
This slot stands out with its unique monochrome design and innovative features that deliver an immersive gaming experience. Game highlights include multiplier symbols, ink stains, Otto’s Eye, tentacle grabs, “Eight Arm Is The Charm” free spins, “Give Me Eight!” bonus rounds, and feature buy options for players seeking immediate action.
The game unfolds in an abandoned city where streets overflow with debris, likely caused by our friend Otto. He accompanies you beside the game grid while you play to a futuristic arcade soundtrack. The most striking aspect of the game is its color scheme—or rather, the absence of one. The game employs a unique monochrome style where only select symbols and Otto himself display color. The slot runs smoothly on most computers, mobile devices, and tablets. Winning combinations form when clusters of 5 or more identical symbols appear adjacent to each other.
Low-paying symbols appear as gray graffiti depicting a fishing hook, lightning bolt, speech bubble, cube, and heart. Landing 26 identical low-value symbols rewards players with a 100x stake payout. High-paying symbols consist of colorful debris such as fish skeletons, beer cans, mushrooms, ice cream cones, and a smiling shark. The reels also feature Multiplier Wilds, Scatters, Epic Scatters, and Otto himself, which we’ll explore in detail in the following section.

Free Spins Mode
Wild symbols contribute to winning combinations by substituting for all symbols except Scatters and Epic Scatters. These Wilds can also appear with random multipliers ranging from 1X to 10X, significantly boosting your potential payouts.
When a winning combination forms, the winning symbols disappear, leaving ink stains in their positions. New symbols then drop from above to fill the vacant spots. This cascading process continues until no more winning combinations form. Ink stains reset between spins or after the Tentacle Grab feature activates.
Otto’s Eye symbols trigger the Tenta-Grab feature when they land on positions with Ink Stains. Upon activation, a tentacle randomly grabs one symbol on the grid and replaces all positions with Ink Stains with this captured symbol, potentially creating new winning combinations.
This feature activates when 3 or more Scatter symbols appear in a single spin. The number of initial free spins equals the number of Scatter symbols that triggered the feature. During these free spins, ink stains persist between spins until the Tenta-Grab feature activates, utilizing all accumulated ink stains for potentially massive wins.
This bonus round triggers when 3 or more Epic Scatter symbols land in a single spin. The number of initial free spins equals the number of Epic Scatter symbols that appeared. During this mode, ink stains remain between spins until used by the Tenta-Grab feature. Importantly, tentacles can only grab Wild or Wild Multiplier symbols during this heightened bonus round.

3X stake = Activates the BonusHunt FeatureSpins mode, where the probability of triggering a bonus game is 5 times higher on each spin.
