SixSixSix: The Basics & How to Play

SixSixSix runs on 5 reels and 4 rows with 14 paylines that pay left to right. All lines are fixed, and you pick your total spin value using the main stake selector.

The minimum is 0.10 credits, while the max ranges from 100 to 180 credits depending on the casino. Every spin can trigger the Wicked Wheels bonus.

How it works:

• Land a “6” scatter on reels 1, 3, or 5 to unlock the Wicked Wheels feature.
• The Blue Wicked Wheel (base game) pays out multipliers, gives multiplier boosts, or starts free spins.
• Hit three “6” scatters at once to access the upgraded Red Wicked Wheels with bigger multipliers and a shot at the max win.
• There are three types of free spins (10 each): Speak of the Devil, Let Hell Break Loose, and What the Hell. Each mode tweaks the wheel bonus.
• The Deal with the Devil lets you risk your bonus for a chance at a higher bonus tier or additional spins.

SixSixSix doesn’t use cascading reels. You’ll need 3 or more matching symbols on a line to score a win.

SixSixSix RTP & Volatility

The return to player (RTP) for SixSixSix is 96.15 percent, which is above the industry average. Over many sessions, the slot is expected to return $96.15 for every $100 played. For more games with high payout rates, check out our high RTP slots page.

The high volatility and above-average RTP combine to offer high-risk, high-reward gameplay. Session swings can be dramatic, so bankroll management is important.

How to Win on SixSixSix: Symbols & Payouts

All payouts below are multiples of your stake per line.

The “Hand” symbol is the highest-paying standard icon at up to 50x for five. The “6” scatter only triggers features and doesn’t pay direct line wins. Wild symbols substitute for others to help you finish winning lines, but exact wild payouts aren’t listed.

To win, line up three or more matching symbols from left to right on a payline. Most of the real excitement comes from bonus features and multipliers.

SixSixSix Max Win

Maximum possible win in SixSixSix is 16,666 times your total spin. You’ll need an extreme multiplier from the Red Wicked Wheel in bonuses, or for the wheel to land the direct max-win sector. It’s as big as Hacksaw slots get.

SixSixSix Strategy & Winning Tips

Every outcome on SixSixSix uses a random number generator, so no trick or approach will improve your odds. When I played, I had demo runs where no bonus landed for ages, then suddenly stacked up wheel features back-to-back. The swings are real.

I’d start with smaller spins to feel out how often those Wicked Wheels land. The major hits won’t come often, but when they do, they’re intense.

Autoplay and quick spin can speed up sessions if you prefer a faster pace — just be sure to use the loss limit settings.

It’s tempting to look for patterns, but there aren’t any. Every spin is a clean slate. Don’t chase, and only play with what feels comfortable.

SixSixSix Visuals & Design

SixSixSix uses a bold 2D cartoon look mixed with horror and occult elements everywhere. Behind the reels, you get a hazy inferno, all smoky reds and black, tiny details peeking through.

Winning spins jump out with lively animations: the paid symbols literally glow and pulse. When Wicked Wheels lands, get ready for flashy wheel animations and ominous visual effects.

The audio made an impression right away. The soundtrack is dark and tense with eerie ambiance, ramping up dramatically when you hit a bonus. That boost in music always sharpens the tension.

Menus are easy to get to in the UI, and it looks good both portrait and landscape on mobile.

Gamesville Verdict: Is SixSixSix a Good Slot Machine?

SixSixSix suits players who want bold volatility, offbeat graphics, and real suspense chasing huge features. If you live for unpredictable sessions and can handle long slow patches, this is definitely in your lane.

What SixSixSix does brilliantly is the Wicked Wheels. The tension as that wheel spins for a mega multiplier or chunks you straight into upgraded free spins matches anything I’ve tried in the past year. The mix of bonus types and risk-reward actually keeps it feeling fresh every time.

Where it struggles is in the base game — it can feel like nothing’s happening until the bonus finally drops. If you want your wins steady and frequent, skip this one.

The demo nails the wild swings and lets you test how the mechanics hit. Try a session before you decide. It’s a slot that takes some nerve.
