Where to Play Octo Attack

Octo Attack Slot Review

Octo Attack is a slot where Earth’s getting invaded by octo-creatures. But don’t sweat it, the main squid dude, Otto, is actually chill and handing out bonuses and features. Yeah, the vibe is kinda grim with all the trash and grayscale, but Otto’s got some tricks up his tentacles to brighten things up with multipliers and wilds. Plus, you could snag a max win of 10,000x your stake.

A slot machine with 6 reels and 5 rows.
Base Game

Octo Attack is a video slot rocking 6 reels and 7 rows, using Cluster Pays. Gotta land 5+ matching symbols to win. Bets range from 0.1 to 100. It’s got medium volatility and a decent RTP of 96.27%. Top prize? 10,000x your bet.

What makes Octo Attack stand out is the weird monochrome look and some cool features that keep things interesting. We’re talking multiplier wilds, ink stains, the Eye of Otto, the Tenta-Grab, «Eight Arm Is The Charm» free spins, «Give Me Eight!» free spins, and a feature buy option.

Octo Attack Slot Information

The game’s set in a messed-up city, streets piled with garbage – probably Otto’s fault. Otto hangs out next to the reels while you spin, with this futuristic arcade soundtrack in the background. First thing you notice? Color’s kinda missing. It’s got this unique grayscale style, with just a few symbols and Otto himself actually colored. You can play it on pretty much anything – desktop, mobile, tablet. Wins happen when you get clusters of 5 or more matching symbols.

Low-paying symbols are gray graffiti – fish hook, lightning bolt, speech bubble, cube, and heart. Hit 26 of the same low-payers and you’re looking at 100x your bet. High-paying symbols are colored trash: fish skeleton, beer can, mushroom, ice cream, and a smiling shark. Reels also have Wild Multipliers, Scatters, Epic Scatters, and Otto himself, but we’ll get into those in the features section.

Octo Attack Slot Features

What’s the max win on Octo Attack slot?

Max win is 10,000x your stake.

What features are in Octo Attack slot?

Features include: Multiplier Wilds, Ink Stains, Eye of Otto and Tenta-Grab, «Eight Arm Is The Charm» Free Spins, «Give Me Eight!» Free Spins, and Feature Buy.

Winning in free spins mode.

Free Spins

Multiplier Wild Symbol

Wilds help you make wins by subbing for any symbol except Scatters and Epic Scatters. Wilds can also show up with a random multiplier from 1x to 10x.

Ink Stains

When you score a win, the winning symbols vanish and leave ink stains behind. Then, new symbols drop down to fill the empty spots. This keeps going as long as you keep getting wins. Ink stains clear between spins, or when the Tenta-Grab feature kicks in.

Eye of Otto and Tenta-Grab

Eye of Otto symbols trigger the Tenta-Grab feature if they land on an Ink Stain. When it hits, a tentacle grabs a random symbol on the grid and replaces all Ink Stain positions with that symbol.

Eight Arm Is The Charm Free Spins

Triggered by landing 3+ Scatter symbols in one spin. You get free spins equal to the number of Scatters that triggered it. During these spins, Ink Stains don’t clear between spins until the Tenta-Grab feature activates, using up all the collected Ink Stains.

Give Me Eight! Free Spins

Triggered by 3+ Epic Scatter symbols in a spin. Again, free spins equal to the number of Scatters. In this mode, Ink Stains also stick around between spins until Tenta-Grab is used. But, the tentacles can only grab Wild or Wild Multiplier symbols.

Menu with 4 different features to choose from.

Feature Buy

Feature Buy

You can buy straight into the features from the base game. Here’s the deal:

3X = BonusHunt FeatureSpins – 5x more likely to trigger a bonus game each spin.

50X = Tentacular FeatureSpins – Guaranteed win and Eye of Otto symbol on every spin.

100X = «Eight Arm Is The Charm» Free Spins.

300X = «Give Me Eight!» Free Spins.

F.A.Q.

What is Octo Attack slot about?

Octo Attack plunges players into a quirky and slightly dystopian world where Earth is under invasion by octo-creatures. However, the central figure, Otto, the main squid, is surprisingly benevolent, offering bonuses and exciting features rather than destruction. The game presents a unique visual style, characterized by a grayscale aesthetic that emphasizes the gritty, trash-filled city backdrop. Despite the somewhat bleak environment, Otto injects vibrancy with colored elements and gameplay mechanics designed to boost your winnings. Expect a blend of unusual charm and potential for significant rewards, including a maximum win of up to 10,000 times your initial bet. This slot offers a distinctive gaming experience that balances a somewhat grim theme with engaging and potentially lucrative gameplay, making it stand out from more conventional slot games. The combination of its unique art style, intriguing features, and substantial win potential makes Octo Attack a compelling option for players looking for something different and exciting.

How do you win in Octo Attack?

Winning in Octo Attack is achieved through the Cluster Pays mechanic. This means instead of traditional paylines, you need to form clusters of five or more matching symbols anywhere on the 6-reel, 7-row grid. The more symbols in a cluster, the larger your win. The game offers a wide betting range, from a minimum of 0.1 to a maximum of 100, accommodating various player budgets and preferences. Octo Attack is classified as a medium volatility slot, suggesting a balance between the frequency and size of wins. It also boasts a Return to Player (RTP) rate of 96.27%, which is considered decent and indicates the theoretical percentage of wagered money that players can expect to win back over time. The ultimate goal is to trigger the game's features and create large symbol clusters to maximize your winnings and potentially reach the top prize of 10,000 times your stake. Understanding the Cluster Pays system is key to enjoying and strategizing your gameplay in Octo Attack.

What are the key features in Octo Attack slot and how do they enhance gameplay?

Octo Attack is packed with a variety of features designed to keep the gameplay dynamic and boost winning potential. These include Multiplier Wilds, which substitute for other symbols and can multiply your wins by up to 10x. The Ink Stains feature is triggered by winning clusters; winning symbols disappear, leaving ink stains, and new symbols cascade down, potentially creating consecutive wins. The Eye of Otto and Tenta-Grab feature adds an element of surprise; when the Eye of Otto symbol lands on an ink stain, a tentacle grabs a random symbol and replaces all ink stains with it, potentially forming new clusters. Furthermore, there are two types of Free Spins: "Eight Arm Is The Charm" and "Give Me Eight!", each triggered by different scatter symbols. These free spins modes alter the Ink Stains mechanic, making them persistent and enhancing the chances of triggering the Tenta-Grab feature repeatedly. Finally, the Feature Buy option allows players to directly access these bonus features, offering a shortcut to the game's most exciting and potentially rewarding elements. These combined features create a layered and engaging gaming experience in Octo Attack.

Can you explain the Ink Stains and Tenta-Grab features in more detail?

The Ink Stains and Tenta-Grab features are central to the dynamic gameplay of Octo Attack. Whenever you achieve a winning cluster, the participating symbols vanish, leaving behind 'ink stains' in their positions. This initiates a cascade effect where new symbols drop down to fill the empty spaces. If these new symbols create further winning clusters, the process repeats, allowing for chain reactions of wins from a single spin. The ink stains act as markers, and they typically clear between spins. However, the 'Eye of Otto' symbol plays a crucial role in interacting with these ink stains. If an Eye of Otto symbol lands on a position marked by an ink stain, it triggers the Tenta-Grab feature. A tentacle animation then appears, reaching onto the reels to grab a random symbol currently present on the grid. Following this, all positions marked by ink stains are transformed into copies of the grabbed symbol. This can lead to significant cluster formations and substantial payouts, especially if the grabbed symbol is of high value or contributes to multiple new clusters across the grid. These features work in tandem to create thrilling moments and increase the potential for big wins throughout your Octo Attack gaming session.

What are the differences between "Eight Arm Is The Charm" and "Give Me Eight!" Free Spins?

Octo Attack offers two distinct Free Spins modes, each triggered by different scatter symbols and offering unique gameplay enhancements. "Eight Arm Is The Charm" Free Spins are activated by landing 3 or more regular Scatter symbols in a single spin. The number of free spins awarded corresponds to the number of triggering scatters. During these free spins, the Ink Stains mechanic is altered; instead of clearing between spins, ink stains persist on the reels. They remain until the Tenta-Grab feature is activated, at which point all accumulated ink stains are utilized. This persistence of ink stains significantly increases the likelihood of triggering the Tenta-Grab feature multiple times throughout the free spins round, potentially leading to a series of symbol transformations and consecutive wins. "Give Me Eight!" Free Spins, on the other hand, are triggered by 3 or more Epic Scatter symbols. These free spins share the persistent ink stain mechanic with "Eight Arm Is The Charm" mode. However, the key difference lies in the Tenta-Grab feature's behavior. In "Give Me Eight!" Free Spins, the tentacle is restricted to grabbing only Wild or Wild Multiplier symbols. This focus on wilds means that the Tenta-Grab feature in this mode is specifically designed to enhance win multipliers and create potentially higher-value clusters, offering a more volatile and potentially more rewarding free spins experience compared to "Eight Arm Is The Charm".

What Feature Buy options are available in Octo Attack and when might I consider using them?

Octo Attack provides players with a Feature Buy option, allowing direct access to various bonus features from the base game for a set price. This can be appealing for players seeking to bypass the standard gameplay and immediately experience the more feature-rich aspects of the slot. The available Feature Buy options include: 'BonusHunt FeatureSpins' for 3x your bet, which significantly increases (by 5x) the probability of triggering a bonus game on each spin. 'Tentacular FeatureSpins' at 50x your bet guarantees a win and an 'Eye of Otto' symbol on every spin, ensuring the activation of the Tenta-Grab feature and potentially leading to substantial symbol transformations. 'Eight Arm Is The Charm' Free Spins can be directly purchased for 100x your bet, providing immediate entry into this free spins mode with its persistent ink stains and Tenta-Grab potential. Finally, 'Give Me Eight!' Free Spins, the most premium option, are available for 300x your bet, granting instant access to the free spins mode where tentacles specifically target Wild and Multiplier Wild symbols, offering the highest volatility and potential for significant wins. Consider using Feature Buy options if you are looking for a more direct route to the game's bonus features, if you have a larger bankroll and are comfortable with higher stakes for potentially quicker and more substantial payouts, or if you simply prefer to experience the most exciting aspects of Octo Attack without waiting for them to trigger organically through base game spins. However, it's important to remember that Feature Buy options involve a higher upfront cost and should be used responsibly within your gambling budget.
