SixSixSix: Slot Overview

Anyone into theology or heavy metal will immediately recognise the nod to the number of the beast in the name of this Hacksaw Gaming release. The game is called SixSixSix, and it pretty much tells you what you’re in for if you choose to step into this digital underworld. Yes, there’s torture, pain, and brutality when the spins turn sour, but there’s also the possibility of hefty rewards when luck swings your way. Here, the number ‘6’ is the key to unlocking bonus action, and the more ‘6s’ that show up, the stronger the feature becomes in technical terms.

Guiding players through the descent are two figures floating at either side of the screen: Balthazar and Beelzebub. These winged, trident-carrying beings occupy a bleak, monochrome realm of greys and gloom, echoing the warning at the gates of Hell in Dante’s Divine Comedy; ‘Abandon hope, all ye who enter here!‘ Visually, it’s very much classic Hacksaw: restrained colour, a couple of companion characters on-screen, and a set of quirky gameplay ideas to keep things engaging.

Set inside a horned frame, the SixSixSix grid delivers 4 rows across 5 reels and runs with 14 paylines. Bets start at 10 c at the minimum and $/€100 at the top end, and there are four choices listed under the bonus buy options. The math model is rated highly volatile at 5 out of 5, which may give some players pause, but the default RTP of 96.15% is perfectly respectable.

The pay symbols don’t bring much colour either. In fact, everything is black and white apart from the top-paying icon—presumably to make it stand out. The five lower-value symbols are crossed bones, an axe, a pack of cigarettes, a drink, and a book, with a 5-of-a-kind paying 3x the bet. Higher-value symbols include a bottle, a skull, two character symbols, and a rocking out hand sign, where 5 matching symbols on a payline return 10 to 50 times the bet. There are no wilds in this game.

SixSixSix: Slot Features

SixSixSix packs in Wicked Wheels and the rewards they can drop, three separate bonus rounds, plus the opportunity to Deal with the Devil. On top of that, there are four bonus buys available.

Wicked Wheels

Blue or Red Wicked Wheels are triggered when the blue or red ‘6’ symbol lands. When a ‘6’ hits (on the leftmost, middle, or rightmost reel), a Wicked Wheel appears in that spot. Only one ‘6’ can land per reel, and only Blue Wicked Wheels appear in the base game. Once activated, the Wicked Wheel spins and awards a prize based on where it stops. If multiple wheels are active, their outcomes are collected from left to right.

• Blue Wicked Wheel values – Max Win, adding multipliers of 5x to 100x, multiplying multipliers of x2-x10, or the FS trigger ‘6’ symbol.
• Red Wicked Wheel values – Max Win, adding multipliers of 10x to 500x, multiplying multipliers of x3-x20.

Free Spins

• Speak Of The Devil Bonus – Landing one ‘6’ symbol on a Wicked Wheel in the base game triggers this feature with 10 free spins. In this bonus, there is an increased chance of landing Red and Blue Wicked Wheels. The ‘6’ symbol does not land on Blue Wicked Wheels in this bonus.
• Let Hell Break Loose! Bonus – Landing a ‘6’ symbol on two Wicked Wheels in the base game triggers this feature with 10 free spins. In this bonus, there is an increased chance of landing Red Wicked Wheels. Blue Wicked Wheels do not appear in this bonus.
• What The Hell Bonus – Landing a ‘6’ symbol on three Wicked Wheels in the base game triggers 10 free spins in this feature. Blue Wicked Wheels do not appear, and a Red Wicked Wheel lands on every spin.

Deal With The Devil

When Speak Of The Devil or Let Hell Break Loose! are triggered, players may be offered the chance to Deal with the Devil. If the offer/gamble is taken, a Deal Wheel appears showing 5, 8, 12, 16, 20, or a ‘6’ symbol. Landing on 5, 8, 12, 16, or 20 determines the number of free spins the player receives. If the wheel stops on ‘6’, players are upgraded into a higher-value bonus round. Speak Of The Devil can upgrade to Let Hell Break Loose! Let Hell Break Loose can upgrade to What The Hell. Bonus modes can’t be downgraded. Players can Deal with the Devil once per bonus level. If Speak Of The Devil is upgraded to Let Hell Break Loose!, they can Deal with the Devil again. No deals are offered during the What The Hell bonus.

Bonus Buys

It wouldn’t feel like a Hacksaw Gaming slot without a few bonus buy options, and SixSixSix includes the following:

• Wicked FeatureSpins – 10x the bet for a higher chance of activating Wicked Wheels. Extremely volatile, RTP 96.24%.
• Red Wicked FeatureSpins – 50x the bet to guarantee landing a Red Wicked Wheel. Blue Wicked Wheels do not appear. Very highly volatile, RTP 96.26%.
• Speak Of The Devil – 100x the bet. Very highly volatile, RTP 96.2%.
• Let Hell Break Loose! – 250x the bet. Highly volatile, RTP 96.22%.

SixSixSix: Slot Verdict

Hacksaw Gaming clearly enjoys a muted palette, and going through SixSixSix brought back plenty of reminders of titles such as Chaos Crew 2, Itero, and Slayers INC. It also leans into the studio’s habit of placing a couple of characters on-screen. As for broader comparisons, SixSixSix’s theme naturally calls to mind other infernal slots too, especially Play’n GO’s Charlie Chance series. Put simply, SixSixSix fits comfortably among familiar company while still delivering its own distinct take on hell-themed risk and reward.

The most notable element in SixSixSix is the Deal with the Devil mechanic. Features like this aren’t exactly rare—AvatarUX games often include a gamble element, for instance—yet free spins gambles are frequently all-or-nothing, and as far as I can recall, this is a first for a Hacksaw Gaming slot. The upside of taking the deal is that you can’t lose the bonus you already triggered. While you could end up with fewer free spins than you would have received, there’s also meaningful upside, whether that’s landing more spins or upgrading into a stronger bonus round. Since the What The Hell bonus can’t be bought, the only ways in are landing 3 ‘6’s in the base game or successfully negotiating your way up via the wheel.

Even though the What The Hell bonus—where a Red Wicked Wheel appears on every free spin—will probably be the most sought-after destination, it’s worth remembering that the 16,666x the stake maximum win is available in every mode. That’s the kind of damage multipliers can do (plus the possibility of an instant result through the Wicked Wheel’s Max Win prize), and when it comes to stacking big multipliers in unusual settings with distinctive feature combinations, Hacksaw Gaming remains hard to beat.
