Hacksaw Gaming’s “Epic” treatment has become a familiar play in the studio’s handbook – take an established title, crank up the win potential, expand the feature buy menu, and repackage it for players who want more firepower. Epic SixSixSix applies that formula to the 2024 original SixSixSix, a devilish Wicked Wheel slot built around prize wheels, multiplier stacking, and a trio of increasingly volatile bonus rounds. The upgrade bumps the max win to 20,666x, adds a High Roller FeatureSpin option with a 1-in-11 shot at the cap, and makes the top-tier What The Hell bonus directly buyable. For players who found the original’s ceiling a little low or its feature buy menu too limited, Epic SixSixSix is a pointed answer.

Play Epic SixSixSix Demo

Spin Epic SixSixSix in demo mode to test the Wicked Wheels and all three bonus tiers risk-free before committing real stakes.

Basics

Epic SixSixSix runs on a 5-reel, 4-row grid with 14 paylines. Stakes range from $/€0.10 to $/€45 per spin, the volatility is rated high, and the RTP sits at 96.27% – a slight bump over the original. When a bonus round is triggered organically, the RTP shifts depending on how players handle the Deal with the Devil gamble: 96.32% when never gambling, 96.30% when gambling once, and 96.27% when gambling twice.

The max win is 20,666x the bet, up from the original’s 16,666x. When that cap is hit, the round ends immediately and any remaining free spins are forfeited.

Paytable

There are no wild symbols. The paytable keeps the original’s mostly monochrome art style: five low-value symbols (crossed bones, axe, cigarettes, drink, and book) each pay 3x for a five-of-a-kind line, while the five premium symbols – a bottle, a skull, two character symbols, and a rocking hand sign — pay between 10x and 50x for a full line.

Wicked Wheels

The core mechanic revolves around Wicked Wheels – prize wheels triggered by landing ‘6’ symbols on reels 1, 3, or 5. Only one ‘6’ can land per applicable reel, and when it does, a Wicked Wheel appears in that position and spins to award a prize. If multiple wheels activate on the same spin, their values are collected left to right.

There are two types:

  • Blue Wicked Wheels appear in the base game and can award adding multipliers (5x–100x), multiplying multipliers (x2–x10), the max win, or an FS-triggering ‘6’ symbol that feeds into the bonus structure.
  • Red Wicked Wheels carry heavier prizes: adding multipliers up to 500x, multiplying multipliers from x3 to x20, or the max win.

Bonus Games

Three bonus rounds sit in a clear hierarchy, each triggered by landing ‘6’ symbols on an increasing number of Wicked Wheels during the base game.

Speak Of The Devil

One ‘6’ symbol on a Wicked Wheel triggers 10 free spins. Both Blue and Red Wicked Wheels appear at an increased rate during this round, but the ‘6’ symbol is removed from Blue wheels, so further bonus upgrades can only come through the Deal with the Devil gamble (see below). This is the entry-level bonus – more frequent to trigger, still capable of decent payouts through stacked wheel prizes, but without the guaranteed Red wheel action of the higher tiers.

Let Hell Break Loose!

Two ‘6’ symbols on Wicked Wheels in the same base game spin triggers 10 free spins. Blue Wicked Wheels are eliminated entirely – only Red wheels appear, and at an increased rate. With Red wheels carrying adding multipliers up to 500x and multiplying multipliers up to x20, this is where the math model starts to show its teeth. The removal of Blue wheels means every wheel spin has genuine top-end potential.

What The Hell

Three ‘6’ symbols across all three Wicked Wheels triggers the top-tier bonus with 10 free spins. A Red Wicked Wheel is guaranteed to land on every single spin, and Blue wheels do not appear. This is the chase target – guaranteed Red wheel action on every spin, with each wheel capable of delivering adding multipliers up to 500x, multiplying multipliers up to x20, or the max win outright. It’s the clearest path to the 20,666x ceiling.

Deal With The Devil

When Speak Of The Devil or Let Hell Break Loose! triggers, players are offered a gamble: the Deal with the Devil. Accepting spins a Deal Wheel containing the values 5, 8, 12, 16, 20, or a ‘6’ symbol.

Landing a number sets the new free spin count for that round – which means the deal can increase or decrease the originally awarded 10 spins. Landing the ‘6’ symbol upgrades the bonus to the next tier: Speak Of The Devil upgrades to Let Hell Break Loose!, and Let Hell Break Loose! upgrades to What The Hell.

Players can Deal with the Devil once per bonus level. That means if Speak Of The Devil upgrades to Let Hell Break Loose!, a second deal is offered for a chance to push all the way to What The Hell. No deal is offered when What The Hell is triggered directly. It’s a high-risk, high-reward mechanic that adds a genuine decision point – take the guaranteed 10 spins, or gamble for an upgrade knowing you might walk away with fewer.

Feature Buys

The Epic upgrade expands the feature buy menu to six options, which is where the “Epic” label earns most of its weight.

Three are FeatureSpin modes:

  • Wicked FeatureSpins at 50x the bet gives a higher chance of activating Wicked Wheels on each spin
  • Red Wicked FeatureSpins at 100x guarantees a Red Wicked Wheel lands on every spin while removing Blue wheels entirely
  • High Roller FeatureSpins at 2,000x, guarantees a Red Wicked Wheel with a 1-in-11 chance of hitting the max win on each spin

Three are direct bonus buys:

  • Speak Of The Devil at 100x
  • Let Hell Break Loose! at 250x
  • What The Hell at 1,000x

Making the top bonus buyable is a significant departure from the original and from Hacksaw’s earlier stance of keeping Hidden Epic Bonuses as organic-only triggers.

Verdict

Epic SixSixSix is a targeted upgrade rather than a ground-up rethink. The core gameplay – Wicked Wheels, the three-tier bonus hierarchy, the Deal with the Devil gamble – is essentially unchanged from the 2024 original, and visually the two are near-identical apart from some extra splashes of cyan. Players coming in fresh won’t notice the seams, but anyone familiar with SixSixSix will recognise the same bones underneath.

Where the Epic version separates itself is in the buy menu and the ceiling. The 20,666x max win is a meaningful step up from 16,666x, and the six feature buy options – particularly the 2,000x High Roller FeatureSpins with their 1-in-11 max win odds and the newly buyable What The Hell bonus – give high-stakes players a set of levers the original never offered. The slightly improved 96.27% RTP is a small but welcome bonus on top.

The honest question is whether that’s enough. Unlike Epic Ze Zeus, which quintupled its predecessor’s top prize, Epic SixSixSix’s ceiling increase is more incremental. For regular base-game spinners, the experience is functionally identical to the original with marginally better numbers. The Epic version is really built for – and will appeal most to – players who buy features and want the option to go straight to the top bonus or roll the dice on a 2,000x High Roller spin. If that’s your style, Epic SixSixSix delivers exactly the expanded toolbox the original was missing. If you’re a grind-it-out base-game player, the original remains just as playable, and this version simply offers slightly better odds on the same ride.
