The Devil's Numbers

Hacksaw Gaming dropped SixSixSix on July 18, 2024, and it turned out to be more than a one-off. The Wicked Wheels mechanic it introduced eventually spawned Pray for Three and Pray for Six, a full trilogy built around spinning wheels and devilish multipliers. But this is where it started. Five reels, four rows, 14 paylines, and two cartoon devils named Balthazar and Beelzebub who look more mischievous than menacing.

The grey-scale palette and playful character design caught people off guard. You'd expect something dark from a game called 666. Instead you get a stylized, almost cute take on damnation. The aesthetic contrast works. It lets the math do the scaring.

Blue Wheels, Red Wheels

'6' symbols land exclusively on reels 1, 3, and 5. One per reel, max. In the base game, only Blue '6' symbols appear, and each one triggers a Blue Wicked Wheel in that position. The wheel spins and awards either an adding multiplier (5x to 100x), a multiplying multiplier (x2 to x10), a free spins trigger, or the max win.

Red Wicked Wheels are where the real numbers live. Adding multipliers jump to 10x through 500x. Multiplying multipliers go up to x20. When multiple wheels land on the same spin, they're collected left to right, so the sequence matters. A Blue Wheel adding 50x followed by a Red Wheel multiplying x10 is a very different outcome than the reverse.

That order dependency is subtle but it's what separates decent hits from headline wins.

Three Tiers, One Hidden

Land one '6' on a Wicked Wheel during base game and you trigger Speak of the Devil. Ten free spins with both Blue and Red Wicked Wheels appearing at higher rates. Two '6' symbols simultaneously gets you Let Hell Break Loose, same 10 spins but only Red Wheels. No Blue ones at all.

Then there's What the Hell. Three '6' symbols at once. A Red Wicked Wheel is guaranteed on every single free spin. You can't buy this one. It's the Hidden Epic, and the only paths in are the organic triple-six trigger or gambling your way up through Deal with the Devil.

Deal with the Devil

When Speak of the Devil or Let Hell Break Loose triggers, the game offers a gamble. Accept and a Deal Wheel appears with these outcomes: 5, 8, 12, 16, or 20 free spins, plus a '6' upgrade symbol. You started with 10 spins, so landing 5 or 8 is a downgrade in quantity. But landing '6' upgrades your entire bonus tier.

Here's the crucial part. You cannot be downgraded to a lower bonus. Land a bad number and you lose some spins but keep your current mode. Land '6' and you move up. You can deal once per bonus level, meaning if you upgrade from Speak to Let Hell Break Loose, you get to deal again for a shot at What the Hell. It rewards the greedy, or at least doesn't punish them as hard as it could.

Sparse Base, Heavy Bonus

Volatility is 5 out of 5. Hit frequency sits at 17.16%, roughly one win every six spins. The base game offers Wicked Wheels and that's about it. No wilds, no tumble, no cascading wins. Critics have called it sparse, and honestly they're not wrong. Hacksaw designed this as a bonus-driven game where base spins are the entry fee.

Buy features range from 10x for Wicked FeatureSpins up to 250x for Let Hell Break Loose. Red Wicked FeatureSpins at 50x guarantee a Red Wheel with no Blue. Speak of the Devil costs 100x. Four RTP tiers exist, with the default at 96.15%. The 16,666x max win is achievable in every game mode, base game included. Bets run 0.10 to 100.
