SixSixSix (Hacksaw Gaming) Slot Review & Demo

🗝️ Key Takeaways

• SixSixSix is a high-volatility slot from Hacksaw Gaming set on a 5x4 grid with 14 fixed paylines, a 96.15% default RTP, and a 16,666x max win that references the devil's number at every turn.
• Blue and Red "6" symbols land on reels 1, 3, and 5, triggering Wicked Wheels that award additive multipliers, multiplicative multipliers, or an instant Max Win, with values collected left to right when multiple wheels are active.
• Three bonus modes escalate from Speak of the Devil (one "6" trigger, both wheel colours) through Let Hell Break Loose (two "6" triggers, Red wheels only) to the What The Hell Hidden Epic Bonus (three "6" triggers, guaranteed Red wheel every spin).
• Deal with the Devil appears after triggering Speak of the Devil or Let Hell Break Loose, offering a gamble wheel that can increase or decrease your spin count or upgrade you to the next bonus tier.
• Operators can deploy three lower RTP variants at 94.19%, 92.17%, and 88.27%, creating a 7.88% spread between the highest and lowest configurations.

SixSixSix from Hacksaw Gaming pulls its entire identity from a single visual commitment. Every element on screen is drawn in the rubber-hose animation style of 1930s cartoons, rendered almost entirely in monochrome.

The grid sits inside a grey, textured backdrop scratched with pentagrams and Latin invocations. At the same time, two animated devil characters flank the reels, bouncing and swaying with the fluid, exaggerated movement that defined the earliest era of American animation.

Balthazar stands to the left in a top hat and tails, grinning with oversized teeth and twirling a pitchfork. Beelzebub mirrors him on the right, lankier and more skeletal, leaning on a trident with the casual menace of a carnival barker waiting for the next mark.

The soundtrack is a gritty, lo-fi blues-jazz loop driven by a raspy upright bass and ticking percussion, punctuated by sinister giggles and deep, booming laughter from the two hosts. The reels slide into place with a soft mechanical sound and land with a metallic ting reminiscent of an antique cash register.

Winning combinations trigger slightly dissonant brass swells that stay in a minor key, and when the bonus rounds activate, the background shifts from grey to fiery teal and cyan, the music picks up into a frantic, higher-stakes arrangement, and both devils become visibly more animated.

🎃 First Impressions

The low-paying symbols are six ritual objects rendered in flat greyscale, including crossed bones, a scythe, a bubbling cauldron, a salt shaker, a leather-bound bible, and a hatchet. All six share identical payout values, and their clean outlines and lack of colour keep them visually subordinate to the characters above them.

The five high-paying symbols are cartoon creatures drawn in the same rubber-hose style. A round-bodied figure in a gas mask and top hat and a hooded grim reaper sit at the lower end, followed by a snarling dark wolf and a wild-eyed white cat, both mid-tier.

The top-paying symbol is a white-gloved hand throwing the devil horns sign inside a red circle, and it pays dramatically more than anything else on the grid. The "6" symbol, rendered as a glowing red numeral inside a teal-and-red frame, is the only special icon on the reels and serves as the trigger for the entire Wicked Wheel system.

The intro screen displays three tombstones summarising the core mechanics. "Spin with Satan" for the Wicked Wheels, "Brave the Bonus" for the three free spins modes, and "Deal with the Devil" for the gamble mechanic, with a red "Hidden Epic Bonus" sticker marking the top tier.

⚙️ Core Mechanics

The grid is 5 reels wide and 4 rows tall, with 14 predefined paylines running from the leftmost position. Only the top-paying combination on each line counts, and totals from all active lines are combined.

Every special mechanic in the game routes through the "6" symbol and the Wicked Wheels it activates.

📊 RTP and Volatility

The highest Return to Player setting is 96.15%, dropping marginally to 96.12% when the base game gamble feature is used a second time. Three additional operator settings sit at 94.19%, 92.17%, and 88.27%, with the gap between top and bottom spanning 7.88%.

The volatility is rated 5 out of 5 on Hacksaw Gaming's skull scale. Extended dry stretches are built into the design, and the base paytable values confirm that this is a game where the feature system carries the weight of the returns.

💀 Symbols and Payouts

Values below are based on a €1.00 bet.

High-Paying:

• Devil Hand (red circle, horns sign): 5 OAK €50.00 / 4 OAK €15.00 / 3 OAK €5.00
• White Cat: 5 OAK €15.00 / 4 OAK €5.00 / 3 OAK €2.00
• Dark Wolf: 5 OAK €15.00 / 4 OAK €5.00 / 3 OAK €2.00
• Grim Reaper: 5 OAK €10.00 / 4 OAK €3.00 / 3 OAK €1.00
• Gas Mask: 5 OAK €10.00 / 4 OAK €3.00 / 3 OAK €1.00

Low-Paying (all six identical):

• Crossbones, Scythe, Cauldron, Salt Shaker, Bible, Hatchet: 5 OAK €3.00 / 4 OAK €1.00 / 3 OAK €0.20

Special Symbol:

• "6" Symbol (red numeral): Triggers a Wicked Wheel of corresponding colour (see Bonus Features).

💰 Betting and Wins

Standard bets sit between €0.10 and €50.00, though feature buys can push beyond that ceiling. If your total win hits the 16,666x cap at any point, the round stops and the payout is awarded regardless of how many free spins remain.

The number is not arbitrary. It is the devil's number stretched to its maximum, and it sits alongside the "6" trigger symbol as part of a thematic commitment that runs through every mechanic.

🎁 The Thrill of the Bonus Features

The feature system in SixSixSix is built around Wicked Wheels triggered by the "6" symbol landing on the grid. Two wheel colours define the base game and bonus split, three escalating bonus modes control the wheel mix, and a gamble mechanic lets you risk your spin count for a shot at upgrading.

🔵 Blue Wicked Wheels

Blue Wicked Wheels are the only wheel type that appears during the base game. They trigger when a blue "6" lands on reels 1, 3, or 5, and the wheel spins in the symbol's grid position.

Blue Wheels contain additive multipliers from 5x through 100x, multiplicative multipliers from x2 through x10, a Max Win slice, and an FS trigger "6" slice that can activate a bonus mode directly from the wheel. When multiple wheels are active on the same spin, their values are collected left to right.

🔴 Red Wicked Wheels

Red Wicked Wheels appear only during bonus rounds and through the Red Wicked FeatureSpins mode. They carry higher values across the board.

Red Wheels contain additive multipliers from 10x through 500x and multiplicative multipliers from x3 through x20, plus the Max Win slice. The FS trigger "6" slice is not present on Red Wheels.

😈 Speak of the Devil

Landing one "6" symbol on a Wicked Wheel in the base game triggers 10 Speak of the Devil free spins. Both Red and Blue Wicked Wheels appear with increased frequency, but the "6" trigger symbol cannot land on Blue Wheels during this mode.

🔥 Let Hell Break Loose

Landing a "6" on two Wicked Wheels simultaneously in the base game triggers 10 Let Hell Break Loose free spins. Blue Wicked Wheels are removed entirely, and only Red Wheels appear with increased frequency.

This is the first mode where every wheel on the grid carries the elevated Red value range.

💥 What The Hell (Hidden Epic Bonus)

Landing a "6" on three Wicked Wheels simultaneously in the base game triggers 10 What The Hell free spins. Blue Wheels are absent, and a Red Wicked Wheel is guaranteed to land on every single spin.

🤝 Deal with the Devil

When Speak of the Devil or Let Hell Break Loose triggers, you are offered a chance to gamble before the round begins. Accepting spins a Deal Wheel containing the values 5, 8, 12, 16, 20, and the "6" symbol.

If the wheel lands on a number, that becomes your new free spins count, which may be higher or lower than the 10 you started with. If it lands on the "6" symbol, you are upgraded to the next bonus tier.

Speak of the Devil upgrades to Let Hell Break Loose, and Let Hell Break Loose upgrades to What The Hell. You can only Deal once per bonus level, but if you upgrade from Speak to Let Hell Break Loose, you are offered the Deal again for a second chance at reaching What The Hell.

The Deal is not offered for What The Hell itself.

⚡ FeatureSpins

Two FeatureSpins modes modify the base game at increasing cost, remaining active until manually disabled.

• Wicked FeatureSpins (10x base bet, Extreme volatility): Higher chance of activating Wicked Wheels.
• Red Wicked FeatureSpins (50x base bet, Very High volatility): Guarantees a Red Wicked Wheel on every spin; Blue Wheels do not appear.

🛒 Feature Buy

Two bonus rounds can be purchased outright.

• Speak of the Devil (100x base bet, Very High volatility): Triggers 10 free spins with increased wheel frequency.
• Let Hell Break Loose (250x base bet, High volatility): Triggers 10 free spins with Red Wheels only.

The What The Hell Hidden Epic Bonus cannot be purchased. It must be triggered naturally with three simultaneous "6" symbols or reached through the Deal with the Devil upgrade path.

🤔 Is This Hacksaw Gaming Game for You?

SixSixSix is built for players who want high-volatility sessions where the base game exists primarily to get you into the bonus modes. The paytable is deliberately thin outside of the Devil Hand premium, and the real returns are locked behind the Wicked Wheel system and the three escalating free spins tiers.

What makes the session distinctive is the Deal with the Devil. When Speak of the Devil or Let Hell Break Loose triggers, you face a genuine decision.

Accept the 10 spins you have, or gamble them on a wheel that could cut you to 5 or upgrade you to the next tier entirely. That tension is rare in modern slots, and it gives every bonus trigger a second layer of stakes.

The FeatureSpins tiers let you force the action if the base game runs cold, but the costs escalate quickly. Red Wicked FeatureSpins at 50x per spin is a serious commitment, and even Wicked FeatureSpins at 10x adds up over a long session.

Players who prefer low-to-medium volatility, steady base game returns, or wheel mechanics with a gentler maths model will find this too aggressive. If you want the wheel-on-grid concept with less punishment, Hacksaw Gaming's Rise of Fortuna offers the same DNA at a fraction of the variance.

🌟 VistaGamble's Honest Assessment

SixSixSix is Hacksaw Gaming committing fully to a theme and a maths model that makes no apologies. The strengths are sharp and the problems are real.

➕ The Positives

• Visual Identity Is Unmatched: No other slot on the market looks or sounds like this. The aesthetic commitment never breaks character, and it gives the game an immediately recognisable identity that stands apart from every competitor.
• Deal with the Devil Adds Real Decision-Making: The gamble wheel before bonus rounds creates a genuine risk-reward moment that most slots never offer, and the upgrade path to What The Hell gives it strategic weight.
• Red Wheel Value Range Is Substantial: Additive multipliers reaching 500x and multiplicatives up to x20 mean that a single well-placed Red Wheel can transform a round, and multi-wheel spins compound that potential dramatically.
• Max Win Cap Fits the Theme: 16,666x is generous by industry standards and woven into the game's identity rather than feeling like an arbitrary number.

➖ The Negatives

• Base Paytable Is Extremely Top-Heavy: The Devil Hand at 50x for 5 OAK dwarfs everything else, and the six identical low-pays at 3x for 5 OAK contribute almost nothing. Without wheels, the base game bleeds.
• RTP Floor Hits Hard: The 88.27% low variant erodes bankrolls aggressively over time, and the 7.88% spread means operator selection directly shapes your expected return.
• What The Hell Requires Three Simultaneous Triggers: Landing "6" on all three eligible reels at once is exceptionally rare, and the only alternative path is chaining two successful Deals, which is itself unlikely.

🔒 Conclusion

SixSixSix is one of the most visually distinctive slots in Hacksaw Gaming's catalogue, and the feature system matches that identity with mechanics that reward patience and punish hesitation. The Deal with the Devil is the centrepiece, a genuine gamble that adds a layer of player agency most bonus triggers lack, and the upgrade path it creates gives every feature entry the potential to escalate.

The maths model is unforgiving by design, and sessions live or die on the Wicked Wheels rather than the paylines beneath them. For players who want high-volatility wheel mechanics inside a presentation that commits completely to its world, this is the slot that delivers.
