Theme and atmosphere
Behind the grid sits a wall covered in graffiti-like scrawl, lit in a louder palette than the original, with cyan doing most of the work. Balthazar and Beelzebub, two winged characters carrying pitchforks, flutter around the reels, and the devil himself turns up to lend the bonus rounds some weight. Symbol art keeps to the theme: crossed bones, an axe, a pack of cigarettes, a drink and a book at the bottom, then a bottle, a skull, two characters and a rocking-out hand sign.
How does the Epic SixSixSix Slot Demo play?
Five reels, four rows, 14 fixed paylines, paying left to right. RTP is published at 96.27%, volatility is high, and the maximum win is 20,666x the bet, with stakes from $/€0.10 to $/€45.
There are no wild symbols anywhere in the game, which puts the entire load on the wheels. Line pays are thin by design: the five low symbols each return 3x the bet for a full five-of-a-kind, the five high symbols pay 10x to 50x. Across a couple of hundred demo spins, that 3x is the number you see most, and it is the reason the base game feels like waiting rather than playing.
⚠️ Worth Knowing: The published RTP is 96.27%, but the game also ships in 94.26% and 92.23% builds, and which one you get depends on the casino. Four percentage points is a real gap on a slot this volatile, so open the info panel before staking money.
What do the Wicked Wheels and bonus rounds do?
A Wicked Wheel takes the place of a ‘6’ symbol when one lands on the leftmost, middle or rightmost reel, with only one ‘6’ allowed per applicable reel, and multiple wheels are collected left to right. Blue wheels appear in the base game only, stopping on the max win, additive multipliers of 5x to 100x, multiplicative multipliers of x2 to x10, or a ‘6’ that opens free spins. Red wheels appear only inside features, dropping the multiplicative range slightly to x3 to x20 but stretching the additive prizes to 500x.
How many ‘6’ wheels land decides the tier. One triggers Speak Of The Devil: 10 free spins with a better chance of both colours, though the ‘6’ no longer shows on blue wheels. Two triggers Let Hell Break Loose!: 10 spins of red wheels only, with the 5x additive prize apparently unavailable there. Three triggers What The Hell, 10 spins with a guaranteed red wheel on every single one.
Speak Of The Devil and Let Hell Break Loose! open with Deal With The Devil. Accept and you spin a wheel showing 5, 8, 12, 16, 20 or a ‘6’, where numbers set your spin count and the ‘6’ promotes you a tier. Since every tier runs 10 spins as standard, the deal is a gamble around that number, and the only genuinely interesting decision the game asks of you. Nothing downgrades, each level deals once (Speak Of The Devil gets a second go if it was upgraded), and What The Hell offers no deal at all.
Six buys are on the menu. Wicked FeatureSpins at 50x raises the wheel rate, Red Wicked FeatureSpins at 100x guarantees a red wheel with no blue ones in play, and High Roller FeatureSpins at 2,000x guarantees a red wheel carrying a 1-in-11 shot at the max win. The three tiers are also purchasable outright at 100x, 250x and 1,000x, top tier included, which is not always granted on a headline bonus.

What are the best casinos for Epic SixSixSix?
Two things matter more than the welcome offer. Which RTP build the operator runs, first, because you can lose four percentage points without being told. Whether the buy menu is switched on, second, since a casino that hides it leaves you with the slowest possible version of this game. Our Wicked Games casino listings are the place to start.
If you plan to buy, read the bonus terms first: check whether feature buys are permitted with bonus funds and whether a 2,000x purchase trips a max-bet rule. The casino bonus hub sets out how the main offer types work.
Play the Epic SixSixSix Slot Demo for free
Everything above runs on play credits, so the Epic SixSixSix Slot Demo costs nothing and asks for no registration. Use it to find out how the base game treats you between wheels, because that stretch is most of your session at real stakes.
💡 Tip: Spin the demo until Deal With The Devil is offered, then accept it a few times. Seeing the wheel come back on 5 instead of 20 is the cheapest way to learn what that gamble actually costs.
New releases land on our upcoming slots page first, and the wider demo slots library is free the same way.
Pros and cons
| ✅ Pros | ❌ Cons |
|---|
| 96.27% top RTP build | No wilds, 3x low-symbol pays |
| Six buys, top tier included | Hard to tell apart from the original |
| 1-in-11 max win on the 2,000x buy | 2,000x entry priced for deep pockets |
| Brighter, sharper art than the original | Slow base game without buys |
Verdict
- The wheels carry this game entirely, and they carry it well.
- Unlocking What The Hell as a direct buy is the most useful change here.
- At small stakes with no buys, you are paying to wait for a second ‘6’.
- Close enough to its predecessor that owning both feels redundant.
Best for: feature-buyers who want the top tier on demand and a stated shot at the max win.
Skip if: you spin low and expect the base game to entertain you.
Set a deposit limit before you start, and treat every feature buy as money already spent.
In summary, Epic SixSixSix from Wicked Games is a 5x4, 14-payline remaster of SixSixSix built around Wicked Wheels that replace ‘6’ symbols, with a published 96.27% RTP, high volatility and a 20,666x maximum win. Its three free spins tiers, Speak Of The Devil, Let Hell Break Loose! and What The Hell, each run 10 spins and cost 100x, 250x or 1,000x to buy. A free demo is playable above.
