Hacksaw Gaming drew the devil in crayon. SixSixSix is a 5×4 horror slot where Balthazar and Beelzebub, two cartoon demons with a taste for chaos, flank a hand-drawn underworld of thick black lines and bleached grey tones. The number six drives the feature set, landing on reels one, three, and five to trigger spinning feature wheels, while the three Free Spins tiers, Speak of the Devil, Let Hell Break Loose, and What The Hell, each include a gamble wheel that sets the stakes before the round begins.
The six symbol comes in two colours, Blue and Red, and is restricted to reels one, three, and five. Each six that lands triggers a Wicked Wheel of the matching colour above its reel, and if multiple sixes appear on the same spin, each triggers its own wheel independently.
Only Blue sixes appear during paid spins, so Blue Wicked Wheels are the only option outside of a bonus round. Blue Wicked Wheels carries four possible results:
Red Wicked Wheels push the adding range from 10x to 500x and the multiplying range from x3 to x20, but carry no free spins trigger.
During bonus rounds, which colours can appear and how often depend on the tier.
When Speak of the Devil or Let Hell Break Loose triggers, the player is offered a Deal with the Devil. If you accept, a ‘Deal Wheel’ opens and can land on 5, 8, 12, 16, or 20, each setting a new free spin count that may be higher or lower than the original 10.
The wheel also contains a ‘6’ segment that upgrades the bonus to the next tier entirely: Speak of the Devil becomes Let Hell Break Loose, and Let Hell Break Loose becomes What The Hell. The player cannot be downgraded.
Three free spins levels sit behind the Wicked Wheels, each determined by how many wheels land on the ‘6’ result at the same time.
What The Hell cannot be purchased and is only accessible through natural triggers or a Deal with the Devil upgrade. The backdrop shifts to red during Speak of the Devil, blue flame effects frame the reels during active bonus play, and both the flames and the red intensify as larger wins land.
Two FeatureSpins options work as ante bets applied to the next spin. The Wicked FeatureSpins costs 10x the total bet and operates at Extreme volatility, while the Red Wicked FeatureSpins costs 50x and runs at Very High.
For direct access to free spins, Speak of the Devil can be purchased for 100x the bet at Very High volatility, and Let Hell Break Loose for 250x at High volatility. The lower volatility labels on the more expensive buys reflect improved starting conditions rather than reduced potential.
Six of the eleven paying symbols in SixSixSix share identical values, each returning €3.00 for five of a kind at a €1.00 bet. The crossbones, axe, turntable, cauldron, bible, and potion are functionally interchangeable on the grid, a flat low-pay tier that keeps regular spins modest and pushes the meaningful returns into the Wicked Wheels system. Above them sit five higher-paying symbols with more separation between values. The potion bottle and Grim Reaper both pay €10.00 for five, the cat and wolf pay €15.00, and the rock hand sign tops the table at €50.00 for a full line.
The grid runs five reels across four rows with fourteen fixed paylines, and bets range from €0.10 to €100.00. There is no wild symbol. The six occupies reels one, three, and five exclusively, triggering wheels but never substituting for other symbols. Without a wild, payline wins depend entirely on natural alignment, which reinforces how much the game leans on its wheel features for the larger payouts.
Hacksaw Gaming places this at the top of their five-point scale, classifying it as very high (extreme) volatility, with a default RTP of 96.15% and a hit rate of around 17%. Operator variants of the RTP run as low as 88.27%, and the demo’s rules screen confirms which version is active. The FeatureSpins and Bonus Buy options each carry slightly different RTPs, all sitting within a narrow band between 96.15% and 96.32%. Maximum win across all modes is 16,666x the total bet.
Values are from the in-game paytable at a €1.00 total bet. The six symbol is excluded from this table as it triggers wheels, not payline wins.

The Wicked Wheels system does most of the work in SixSixSix, and it does enough to earn a 4. Two distinct wheel sets with meaningful gaps between their multiplier ranges, a gamble option that makes the player an active participant before every bonus round, and a 16,666x top end that the Red Wheel values can approach when three land together on a single spin. The art direction gives the game its identity, the wheels give it its payouts, and the score would sit higher if Hacksaw had built a second feature behind them.
Paid spins at a €1.00 bet were quiet for the first hundred rounds, with only two Blue Wicked Wheels appearing and both landing on the same 5x adding multiplier for €5.00 each. A Red Wicked FeatureSpins attempt at €50.00 returned a 15x adding multiplier for €15.00, and two Speak of the Devil buys at €100.00 apiece came back at €38.20 and €25.00. The Deal with the Devil gamble pushed the first round from 10 to 12 spins and dropped the second from 10 to 5, and neither came close to covering its buy-in. Both Blue and Red Wheels land in Speak of the Devil, but the Blue results in this session stayed low.
Let Hell Break Loose at €250.00 switched everything to Red Wicked Wheels, and the difference was immediately apparent. A 25x adding multiplier on spin three, a 100x on spin seven, and a 10x on spin nine all landed within the Red range that Blue Wheels cannot reach, and the round finished at €135.40. Still a loss, but the individual spin values showed what the Red set is capable of when the sixes cooperate.
A second Let Hell Break Loose round turned the session. The gamble wheel set the count at eight free spins, and by spin five, the running total sat at €70.00 from scattered adding multipliers. Then three sixes landed simultaneously. Three Red Wicked Wheels spun above reels one, three, and five, and their combined result delivered a €240.00 Super Mega Win on a single spin. The screen flashed between deep red and oversized blue flames as the win banner appeared. An Epic Win of €250.00 followed later in the round, bringing the total to €560.00 and pulling the session balance into profit for the first time.
Five rounds of bonus play, and every one of them came down to what colour the wheels were and what numbers they landed on. The escalation from Blue to Red Wheels across the three tiers gives the feature a clear arc, and when the Red set fires on all three reels at once, the numbers land hard enough to justify the grind to get there. But there is no second feature waiting behind the wheels, no pick round, no progressive build across a bonus. The Deal with the Devil gamble is the one decision point, and beyond it, the player watches wheels spin. Hacksaw’s black-and-white art carries the atmosphere, the multiplier ranges carry the math, and for a game built entirely around one system, the system delivers.
