Hacksaw Gaming has summoned something genuinely sinister with SixSixSix—and we’re not just talking about the obvious triple-six branding. Released in July 2024, this monochrome hellscape ditches traditional wilds and scatters in favor of Wicked Wheels that can multiply your stake by up to 16,666x. Two cartoon demons named Balthazar and Beelzebub orchestrate the chaos from the sidelines, watching as blue and red ‘6’ symbols trigger wheels that either save your session or send it straight to the underworld. It’s quintessential Hacksaw: maximum volatility wrapped in a theme that doesn’t apologize for being dark.

Theme and Visuals
SixSixSix commits fully to its hellfire aesthetic. The game unfolds in stark monochrome—blacks, whites, and shades of gray dominate the screen, broken only by splashes of crimson red when those critical Red Wicked Wheels appear. Balthazar and Beelzebub, the twin demons flanking the reels, are rendered in a playful cartoon style that somehow makes them more unsettling rather than less. They grin and gesture throughout your session, celebrating when Wicked Wheels land and looking genuinely disappointed when you hit dead spins.
The symbol set includes appropriately dark imagery: bones, an axe, cigarettes, a bowl, and a bible form the low-paying tier, while a flask, skull, dog, goat, and the iconic white “rocking out” hand gesture populate the premium positions. The design work is crisp and immediately readable despite the limited color palette. Hacksaw Gaming clearly studied the aesthetic homework from slots like Nolimit City’s darker releases, then added their own signature cartoonish edge.

How to Play SixSixSix
Despite the intimidating theme and extreme volatility, getting started with SixSixSix is straightforward. Here’s your step-by-step breakdown:
- Set Your Stake: Adjust your bet from €0.10 to €100 using the controls. With 5/5 volatility, expect extended dry spells—size your bets accordingly to survive 50+ dead spins.
- Spin the 5×4 Grid: The game uses 14 fixed paylines. Standard wins require matching symbols on adjacent reels from left to right, just like conventional slots.
- Watch Reels 1, 3, and 5: These are the only positions where Blue ‘6’ symbols can land during base game play. Only one ‘6’ can appear per eligible reel on any given spin.
- Trigger Wicked Wheels: When a Blue ‘6’ lands, it activates a Wicked Wheel in that exact position. The wheel spins and awards either instant multipliers (5x to 100x), multiplying multipliers (x2 to x10), or a ‘6’ symbol that triggers free spins.
- Collect Multiple Wheels: If you land multiple ‘6’ symbols on the same spin, each triggers its own independent Wicked Wheel. The more wheels, the higher your chances of stacking multipliers or triggering upgraded bonuses.
- Make Deals with Devils: When you trigger a bonus, you’ll be offered a Deal with the Devil. Accept to spin a Deal Wheel that can increase your free spins (5, 8, 12, 16, 20) or award a ‘6’ symbol that upgrades you to the next bonus tier.
- Consider Bonus Buys: Four purchase options let you skip the base game grind, ranging from 10x (Wicked FeatureSpins) to 250x stake (Let Hell Break Loose). Weigh the cost against your bankroll tolerance.
Pro Tip: The Deal with the Devil feature creates a fascinating risk-versus-reward decision. If you’re already in the second-tier bonus (Let Hell Break Loose), accepting the deal risks downgrading your spin count for a chance at the ultimate What The Hell mode with guaranteed Red Wheels. Only accept deals when you’re in lower-tier bonuses or when your bankroll can absorb the gamble.
Symbols and Paytable
SixSixSix uses a two-tier paytable that’s straightforward but punishing without the Wicked Wheels to amplify wins. Here’s the complete breakdown for five-of-a-kind combinations:
| Symbol | Type | 5-Symbol Payout |
|---|---|---|
| Rocking Hand (white hand) | Premium | 50x stake |
| Goat | Premium | 15x stake |
| Dog | Premium | 15x stake |
| Skull | Premium | 10x stake |
| Flask | Premium | 10x stake |
| Bible | Low-pay | 3x stake |
| Bowl | Low-pay | 3x stake |
| Cigarettes | Low-pay | 3x stake |
| Axe | Low-pay | 3x stake |
| Bones | Low-pay | 3x stake |
Notice the absence of wild symbols. SixSixSix doesn’t use traditional substituting wilds, which means you need precise symbol alignment for wins. The game compensates through its Wicked Wheel mechanic—when those Blue and Red ‘6’ symbols land, they don’t contribute to paylines but instead trigger wheels that can deliver multipliers far exceeding any standard symbol combination.
The low-paying tier is notably compressed—every low symbol pays the same 3x for five-of-a-kind. This design choice emphasizes that base game wins are more about keeping you afloat between Wicked Wheel triggers rather than delivering meaningful returns. You’re hunting for those ‘6’ symbols, not standard symbol combinations.
Slot Features
Wicked Wheels
The entire game revolves around Wicked Wheels—literal spinning wheels that appear when ‘6’ symbols land on reels 1, 3, or 5. Think of them as mini bonus rounds that trigger mid-spin rather than requiring scatters.
Blue Wicked Wheels appear during base game play and contain:
- Adding Multipliers: 5x, 10x, 15x, 20x, 25x, 50x, 100x—these add to your current spin’s win
- Multiplying Multipliers: x2, x3, x4, x5, x10—these multiply your current total (including previously awarded multipliers)
- Free Spins ‘6’ Symbol: Triggers bonus rounds based on how many ‘6’ results you land from active wheels
- Max Win: Instant jackpot—land this and you’re done at 16,666x
Red Wicked Wheels only appear during bonus rounds and are significantly more powerful:
- Adding Multipliers: 10x, 15x, 20x, 25x, 50x, 100x, 250x, 500x—notice the floor is already 10x
- Multiplying Multipliers: x3, x4, x5, x10, x15, x20—substantially higher than Blue Wheels
- Max Win: Same instant jackpot potential
The key strategic element: multiplying multipliers compound with adding multipliers. If you land a 50x adding multiplier, then hit a x5 multiplying multiplier, that 50x becomes 250x. Stack multiple wheels on the same spin and the mathematics get genuinely exciting—this is how the 16,666x max win becomes achievable rather than theoretical.
Deal with the Devil
Every time you trigger a bonus round, Balthazar and Beelzebub offer you a deal. Accept, and a Deal Wheel appears with six possible outcomes:
- Number Values: 5, 8, 12, 16, or 20 free spins replace your current spin count
- ‘6’ Symbol: Upgrades you to the next bonus tier (Speak of the Devil → Let Hell Break Loose → What The Hell)
This creates genuine tension. You’ve just triggered 10 spins of Speak of the Devil. Do you accept a deal that might downgrade you to 5 spins, or could upgrade you to Let Hell Break Loose where Red Wheels dominate? Hacksaw Gaming turned bonus triggers into decision points rather than automatic celebrations.
Slot Bonus Features
Bonus Buy Options
SixSixSix offers four distinct bonus buy paths, each with slightly different RTP profiles and volatility characteristics:
| Buy Option | Cost | RTP | What You Get |
|---|---|---|---|
| Wicked FeatureSpins | 10x stake | 96.24% | Enhanced base game with dramatically increased Wicked Wheel probability |
| Red Wicked FeatureSpins | 50x stake | 96.26% | Guaranteed Red Wicked Wheel on next trigger; Blue Wheels removed |
| Speak of the Devil | 100x stake | 96.20% | Instant entry to first-tier bonus with 10 free spins |
| Let Hell Break Loose! | 250x stake | 96.22% | Instant entry to second-tier bonus with Red Wheel focus |
Strategic Analysis: The Wicked FeatureSpins at 10x stake offer the best RTP (96.24%) and serve as a middle ground between grinding base game and committing to full bonus buys. You’re still playing the base game, but with Wicked Wheel frequencies that make the experience substantially more active. The Red Wicked FeatureSpins at 50x is interesting if you’re specifically hunting Red Wheel multipliers without committing to a full bonus.
The direct bonus buys (100x and 250x) appeal to impatient players or those with sufficient bankroll to absorb multiple failed attempts. Remember that 250x stake is a serious commitment—at a €1 bet, you’re spending €250 for 10 spins that, while focused on Red Wheels, still require favorable wheel outcomes to deliver meaningful returns.
RTP and Volatility
SixSixSix launches with a 96.15% RTP in its default configuration—comfortably above the industry standard. However, operators can select from three lower RTP variants (94.19%, 92.17%, 88.27%), so always verify which version your casino runs before committing serious bankroll. The 17% hit frequency delivers roughly one win every six spins, which is generous for extreme volatility—but most of those returns are sub-1x low-symbol combinations that barely dent accumulated losses.
The 5/5 volatility rating is a genuine warning, not marketing hyperbole. Expect extended dry spells of 50+ dead spins where nothing meaningful lands. The variance stems from the gulf between those frustrating base game grinds and the explosive potential when multiple Wicked Wheels trigger simultaneously. The 16,666x max win (approximately 666 × 25) is achievable through multiplicative stacking of Red Wheel multipliers during What The Hell mode—not a theoretical ceiling, but a realistic target for patient players who reach the top-tier bonus.

How to Max Win on SixSixSix
Base Game Max Win
Max win is technically possible. Land 3 Blue Wicked Wheels with the right combination of adding and multiplying multipliers, or hit the direct Max Win slice on a wheel. Rare but achievable.
Free Spins (Where Max Wins Actually Happen)
Three tiers based on how many ‘6’ symbols trigger simultaneously:
Speak of the Devil (1 wheel trigger / 100x buy): 10 free spins with increased Blue and Red Wheel frequency. Entry-level bonus—good, but not the max-win zone.
Let Hell Break Loose (2 wheels trigger / 250x buy): 10 free spins with Red Wheels only (no Blue). Higher multipliers (up to 500x adding, x20 multiplying) make this significantly more dangerous.
What the Hell (3 wheels trigger – NOT buyable): 10 free spins with a guaranteed Red Wicked Wheel on every spin. This is the max-win factory. Every spin delivers Red Wheel prizes, stacking adding and multiplying multipliers relentlessly until the game caps you at 16,666x.
Deal with the Devil (Gamble Feature)
When Speak of the Devil or Let Hell Break Loose triggers, you can gamble. The Deal Wheel can award 5, 8, 12, 16, or 20 free spins—or land on ‘6’ to upgrade your bonus to the next tier. Speak of the Devil → Let Hell Break Loose → What the Hell.
You can’t lose your bonus entirely (can only win or upgrade), making this a rare player-friendly gamble. What the Hell cannot be gambled or bought—natural trigger or upgrade only.
Typical Max Win Script
- Trigger Let Hell Break Loose or What the Hell
- Gamble up to What the Hell if possible
- Guaranteed Red Wheels land every spin
- Stack adding multipliers (250x, 500x) with multiplying multipliers (x15, x20)
- One monster combination pushes total past 16,666x and caps you out

Conclusion
SixSixSix is Hacksaw Gaming at peak volatility—a 5/5 variance slot where Wicked Wheels replace traditional wilds and scatters, delivering either crushing dry spells or explosive 16,666x potential through multiplicative Red Wheel stacking. The innovative mechanics and committed hellfire aesthetic make it compelling for experienced high-variance enthusiasts, but this is not a casual session slot: expect brutal bankroll attrition between those rare What The Hell triggers where the math actually works in your favor. If you understand extreme variance demands patience, proper bankroll management, and emotional detachment from short-term results—and you verify your casino runs the 96.15% RTP version—then Balthazar and Beelzebub have prepared something genuinely special.
FAQs
SixSixSix has a default RTP of 96.15%, which is above the industry standard. However, Hacksaw Gaming provides operators with three additional RTP variants: 94.19%, 92.17%, and 88.27%. Always check which version your casino is running before playing, as the difference between 96.15% and 88.27% significantly affects your expected returns over time.
Wicked Wheels trigger when Blue or Red ‘6’ symbols land on reels 1, 3, or 5. Each wheel spins to award either adding multipliers (5x to 500x depending on wheel color), multiplying multipliers (x2 to x20), a ‘6’ symbol that triggers free spins, or the instant max win. Multiplying multipliers compound with adding multipliers, so a 50x adding multiplier followed by a x10 multiplying multiplier becomes 500x.
The maximum win in SixSixSix is 16,666x your stake—thematically appropriate for a slot named after the number of the beast. This maximum is achievable through the multiplicative stacking of Red Wicked Wheel multipliers during bonus rounds, particularly during the What The Hell mode where Red Wheels are guaranteed on every spin.
What The Hell requires landing ‘6’ symbol results on three Wicked Wheels simultaneously during a single base game spin—exceptionally rare. Alternatively, you can trigger Speak of the Devil (1 wheel) or Let Hell Break Loose (2 wheels), then use the Deal with the Devil gamble feature to upgrade through tiers. Each Deal Wheel spin can award a ‘6’ that promotes you to the next bonus level. Crucially, What The Hell cannot be purchased directly.
No. SixSixSix carries a 5/5 volatility rating with extreme variance. Casual players accustomed to medium volatility slots will find the dry spells punishing and the bankroll swings uncomfortable. This game is designed for experienced players who understand extreme variance, have sufficient bankroll to absorb extended losing streaks, and specifically seek high-risk, high-reward gameplay.
SixSixSix offers four bonus buy options: Wicked FeatureSpins (10x stake) for enhanced base game play, Red Wicked FeatureSpins (50x stake) guaranteeing Red Wheels on triggers, Speak of the Devil (100x stake) for direct first-tier bonus entry, and Let Hell Break Loose (250x stake) for second-tier bonus access. What The Hell mode cannot be purchased—it must be triggered naturally or upgraded via Deal with the Devil.
