Game Overview of Octo Attack Slot

Stepping into Otto's underwater world reveals a uniquely designed slot machine that breaks traditional molds. Hacksaw Gaming has created a gritty, urban-inspired aquatic adventure that combines innovative mechanics with striking visuals.

Reel layout and cluster mechanics

Octo Attack features an expansive 6-reel, 5-row grid that uses a cluster pays system rather than traditional paylines. Success comes from connecting at least five matching symbols horizontally or vertically anywhere on the grid. This creates a dynamic gameplay experience as winning clusters can form in numerous positions.

Furthermore, the game incorporates a cascading reels mechanic that keeps the action flowing. After each win, the matching symbols vanish from the grid, leaving behind Ink Stains that mark their positions. New symbols then tumble down to fill the empty spaces, potentially creating additional winning combinations from a single spin. These Ink Stains play a crucial role in the game's bonus features, which we'll explore later.

Volatility and max win potential

Hacksaw Gaming has rated Octo Attack with medium volatility (3 out of 5), striking an excellent balance between frequent payouts and substantial win potential. The game boasts an RTP of 96.27% when betting between $0.10 and $100 per spin.

In addition, the hit frequency of approximately 33.96% means you can expect wins around every third spin on average, keeping gameplay engaging without excessive dry spells. The most exciting aspect, however, is the massive 10,000x maximum win potential that's achievable in every game mode. With maximum bets, this could translate to a staggering $1,000,000 payday.

Symbols and Payouts

The underwater theme of Octo Attack is brought to life through its beautifully designed symbols and background. Much like the sea floor you can find smaller  gray rewards at the bottom and keep an eye for more exotic and colorful high paying symbols. Let’s break down all the symbols of the game:

Low-Paying Symbols

The monochrome symbols represent Octo Attack's low-paying icons, featuring black and gray hooks, bolts, speech bubbles, boxes, and hearts. These symbols appear frequently during gameplay, helping maintain your bankroll with smaller wins. Five-of-a-kind clusters of these symbols pay between 0.1 to 1 times your bet, while forming massive clusters of 26 or more identical symbols can reward you with up to 100 times your stake.

‍

High-Paying Symbols

Beyond the basics, the high-paying symbols add vibrant splashes of color to the reels. These premium icons include fish carcasses, foaming beer cans, exotic mushrooms, ice cream, and smiling sharks. These colorful symbols deliver substantially better payouts, with five-of-a-kind clusters worth 1 times your bet. To begin with, the real treasure comes when you land 26+ symbols in a cluster, which can pay an impressive 100 to 500 times your wager.

Special Symbols

In addition to the regular symbols, Octo Attack features five special symbols that can significantly boost your winnings:

• Wild Symbol:Represented by stylized “W”, the Wild substitutes for all symbols in the paytable and can randomly include multiplier values from x1 to x10 the base bet.
• Ink Stains: Whenever a winning combination lands, the combination is collected and the symbols replaced by Ink stains, which are key to the Tenta Grab Feature. 
• Eye of the Otto: Represented by a closeup of the eye of the Octopus, this symbol triggers the Tenta-Grab Mechanic which selects a random symbol to replace all Ink Stain symbols across the reels.
• Free Spins (Normal): Represented by a red traditional “FS” symbol, the Scatter symbol triggers the Eight Arm is the Charm Free Spins mode.
• Free Spins (Epic): Represented by a yellow traditional “FS” symbol, the Scatter symbol triggers the Give me Eight! Free Spins mode.

‍

Bonus Features

One of the standout aspects of Octo Attack is its variety of exciting bonus features. From the Tenta-Grab Mechanic to the Eight Arm is the Charm and Give me Eight! Free Spins modes, these bonuses not only enhance the gameplay experience but also increase your chances of landing big wins:

Tenta-Grab Mechanic

The Tenta-Grab Mechanic starts with the Ink Stains that replace the winning combinations. When a Eye of the Otto symbol lands, it randomly selects one symbol on the grid and replaces all Ink Stain symbols across the reels. 

Unlike many other substitution features from other slot casino games, the Tenta-Grab Mechanic can also choose and replace Ink Stains with Special Symbols like the FS Scatter (Normal and Epic), Wilds and Wild Multiplier symbols. This feature is a massive opportunity to land 30 Wilds or Scatters that can lead to massive wins.

‍

Eight Arm is the Charm Free Spins

The Eight Arm is the Charm Free Spins feature is triggered by landing three or more red “FS” Scatter symbols anywhere on the reels. You will be awarded one additional free spin for every additional Scatter symbol you land, beyond the minimum 3 FS requirement. Additionally, during the Free Spins mode, you will be awarded an extra free spin for every 3 FS Scatters you land.

An exciting addition to the Free Spins mode is that the Ink Stain symbols from the winning combinations do not disappear with every spin; these remain in place, overlapping with new symbols until the Tenta-Grab Mechanic is triggered by the Eye of the Otto and all Ink Stains are replaced by more winning combinations.

Give me Eight! Free Spins

Similarly, Give me Eight! Free Spins bonus is triggered by 3 or more Epic Yellow FS symbols. Like the Eight Arm is The Charm mode during the free spins, for every 3 Epic FS symbols, you will get awarded one additional free spin.

In this mode Ink Stains are still generated after winning combinations and are eventually replaced by a random symbol whenever the Tenta-Grab Mechanic is triggered. Here is the twist, in the Give me Eight! mode, the Tenta-Grab Mechanic only selects Special symbols including the Wilds and Scatters, awarding you additional multipliers and free spins to reach that big payout.

Bonus Buy   

Like many other Hacksaw Gaming slot machines, Octo Attack gives the choice of jumping right into the action by paying a premium for better drops or buying the Free Spins modes directly: 

• Bonushunt Featurespins: For x3 the base bet, each spin will be 5 times more likely to trigger a bonus game.
• Tentacular Featurespins: For x50 the base bet, each spin guarantees at least one winning combination along with one Eye of the Otto symbol triggering the Tenta-Grab Mechanic.
• Eight Arm is The Charm: For x100 the base bet, you will get 10 free spins in the Free Spins mode.
• Give me Eight!: For x300 the base bet, you will receive a guaranteed 10  free spins on the Give me Eight! Free spins mode, which has a Tenta-Grab Mechanic that only selects Special Symbols.

Betting Options and Payouts

Octo Attack caters for all budgets, with a wide range of betting options available. Players can place bets ranging from $0.10 credits to $100 per spin, making it attractive for both micro bettors and high stakes gamblers.

The game’s top payout potential is 10,000x your initial bet, which offers a significant payout for players lucky enough to trigger the maximum win, $1,000,000 if you play your cards right and luck is on your side.

Strategy Tips for Winning at Octo Attack

Although slot games are largely reliant on luck or numbers, depending on who you ask, there are a few strategies you can use to maximize your chances of winning:

1. Start Small

You can either start on the Demo mode or place smaller bets until you get familiar with this online slot game. It’s more exciting to play real money casino games, so place a minimum bet to have more fun and get acquainted with all the game’s key mechanics.

2. Aim for Free Spins

The Free Spins rounds is where the game’s biggest payouts are likely to occur, especially with the Tenta-Grab Mechanic feature that boosts payouts of the free spin mode. Landing at least three FS Scatter symbols, normal or epic, should be your priority, as the Free Spins modes are your best chance to hit those massive wins.

3. Manage Your Bankroll

Since Octo Attack is a medium-volatility slot, you’ll want to manage your bankroll wisely to stay in the game long enough to trigger the bonus features. Consider placing moderate bets that allow you to play for longer periods without diluting your funds too quickly.

4. Bonus Buy

Once familiarized with the game, consider jumping directly into the bonus modes, a big win may come right from the start and you might continue playing with essentially free money.
