Octo Attack Slot Review

Octo Attack is an action-packed online slot from Hacksaw Gaming featuring innovative bonuses and features, including wild substitution, multipliers, and cascading reels. Let’s delve into the details to see what you can expect from the Octo Attack slot game.

Theme

The slot plunges players into an intense adventure featuring Otto, a massive, mischievous octopus causing havoc. The game blends a unique street-style design with its aquatic theme. Otto the Octopus adds personality as his tentacles wave and interact with the grid, inviting players to partake in his chaotic mischief.

Graphics, Sounds & Animations

The classic monochrome design of Octo Attack features a street as the backdrop. The reels are also black and grey, matching the background design. On the left side of the reels, the Octopus moves from left to right, adding a colorful and playful touch to the game.

 

The game also features a menacing, electro-style soundtrack that intensifies the gameplay. The sound and the graphics help set your mood for the fun-filled adventure, keeping you immersed in the game. Even if the graphics might look a bit boring at first glance, the occasional visual and sound effects make up for it.

Max Win, RTP, and Volatility

The Octo Attack slot‘s maximum achievable win is 10,000 times the bet, which activates when you land special combinations or features. Using the max bet option can increase your chances of landing the maximum win. If you land the max win during free spins, the game returns to the main screen, and any other free spins are discarded. 

 

The game has an RTP value of 96.27%. However, that value can change, ranging from 96.27% to 96.31%, depending on the bonus purchased with the buy feature. Overall, the RTP value is decent and is likely to give you satisfactory returns. But keep in mind that RTP is a theoretical value simulated by calculating 10,000,000,000 rounds.

 

Additionally, the slot game has a medium volatility scale, which means you will enjoy moderate wins with a moderate frequency. That makes it more balanced compared to high- or low-volatility slots.

Octo Attack Gameplay

Like most slot games from Hacksaw Gaming, Octo Attack comes with simple gameplay. Therefore, you can easily grasp the rules even without any experience.

 

After launching the game, you need to place a bet that should be within your betting budget. The game has a bet size between €0.10 and €100, which caters to all players, regardless of their bankroll. You can change or adjust the bet level by clicking on the arrows.

 

Once your bet is set, you can click the play button to rotate the reels. Players can also use the space bar on their keyboard to initiate a spin. The game has an autoplay feature that allows you to set predetermined spins. By doing that, you don’t need to click or tap every time; you can sit back, and the game will spin the reels for you. The autoplay feature can be disabled anytime.

 

The game also allows advanced settings like turbo play, which increases the speed of the reels.  To trigger a win, you need to land 5 or more connecting symbols of the same kind anywhere on the reels. Each winning combination activates the cascading reels, where winning symbols are removed and new ones drop in. This continues until there are no more winning combos.

 

There are quite a lot of symbols in Octo Attack, including standard paying ones and several special symbols with unique roles. First, let’s see the standard ones with their values below:

 

Symbol	Cluster of 5	Cluster of 6	Cluster of 7	Cluster of 8	Cluster of 9-10	Cluster of 11-12	Cluster of 13-25	Cluster of 26+

Features

The Octo Attack slot is packed with thrilling bonus features that will have you hooked in no time. Whether it’s the free spins or Otto’s Tenta-Grab feature, these features have some rewarding sessions in store for you. Let’s see how they work below.

 

Wild Symbols and Wild Multipliers

 

W represents the wild, which can replace any regular symbol to complete a winning combination. The wild symbol can also be accompanied by one of the following multipliers to increase your winnings: 1x, 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, and 10x.

 

Ink Stain

 

When a win occurs on the grid, the system calculates the winning prize and removes the winning symbols. When this happens, new symbols roll down to fill the empty position on the grid. The winning positions will be marked with Ink Stain, which are removed after they are used by the Tenta-Grab mechanic explained below.

 

Eye of Otto and the Tenta-Grab Mechanic

 

Landing the Eye of Otto symbol on the grid with Ink Stain activates the Tenta-Grab mechanic. When this happens, Tenta-Grab randomly selects one symbol, replacing all ink-stained positions and itself with the selected symbol.

 

The Tenta-Grab mechanic can grab any symbols, including FS symbols, wilds, low- and high-value symbols. If the mechanic grabs a wild, the replacing symbol will be either a wild or wild multiplier with higher or lower values than the chosen symbol.

 

8th Arm is the Charm

 

Get at least 3 normal FS scatters on the reels during the base game to activate this feature with free spins. The number of free spins will be equal to the number of FS symbols that trigger the round. During this round, Ink Stains are not removed from the reels between spins until they are grabbed by the Tenta-Grab.

 

Landing more normal FS symbols during this round awards extra free spins. For every three normal FS symbols in view, the game awards 1 additional spin.

 

Give Me Eight

 

3 epic FS symbols on the reels during the base game trigger this bonus. Again, the number of free spins you’ll receive equals the number of epic scatters in view. For every 3 epic FS symbols in this round, you will receive 1 extra spin.

 

This feature is mostly the same as the regular free spins. However, the difference is that only wild symbols can be used by the Tenta-Grab in this round.

 

Bonus Buy Options

 

If you can’t wait to land symbols to activate the bonus features, you can opt in for the buy feature. Keep in mind that the buy feature comes with additional costs and can change the RTP value, as stipulated below:

• The RTP when buying BonusHunt FeatureSpins is 96.31%.
• The RTP when buying Tentacular FeatureSpins is 96.27%.
• The RTP when buying Eighth Arm is the Charm is 96.27%.
• The RTP when buying Give Me Eight is 96.28%.
