What Is SixSixSix?

Players must redeem themselves if they are to escape the fiery pits of Hell in SixSixSix, courtesy of Hacksaw Gaming. This high-volatility slot takes players into a dark, infernal world filled with ominous symbols and a chilling atmosphere, though the studio's characteristic rubber-hose animation aesthetic — channeling the same playful, uncanny mood seen in titles like Booze Bash and The Count — keeps the presentation from tipping into full horror immersion. Underneath that playful, uncanny charm sits a serious high-volatility engine designed specifically for patient players.

The grid runs on a 5-reel layout with 14 fixed paylines, a deliberate step away from the more complex cluster mechanics that often show up in comparable high-volatility releases, evaluating winning combinations left to right from the leftmost reel.

The Wicked Wheels Feature

The Wicked Wheels feature stands as the cornerstone of SixSixSix, driving the game's entire excitement and reward structure. Triggered by landing the iconic '6' symbols specifically on reels 1, 3, or 5, this feature unveils a wheel that spins to award various prizes — capable of appearing on any spin to unlock multipliers or send players straight into one of the game's dedicated bonus rounds.

Deal with the Devil and Three Free Spins Modes

Three different free spins bonuses are available thanks to the Wicked Wheels system, each offering its own escalating rhythm as players progress deeper into Hell's domain. The Deal with the Devil gamble feature adds most of the tension found in the game, letting players risk their current position for a shot at reaching higher bonus tiers — a genuinely high-stakes decision point that rewards confident, calculated risk-taking.

A Bonus Buy option lets players instantly access the Free Spins feature for a direct cost, skipping the wait for a natural Wicked Wheels trigger entirely.

RTP, Volatility and the 16,666x Ceiling

Default RTP is 96.15%, with 94.19%, 92.17% and 88.27% configurations also available depending on the operator. Volatility carries the studio's maximum 5 out of 5 rating, and the 14-payline structure can lead to genuinely long periods without significant returns during quieter stretches.

The 16,666x max win is impressively symbolic, fitting perfectly within the devil and hell theme, and remains achievable across every single game mode including the base game and all bonus features. Bets run $0.10 to $100 per spin.

Our Verdict

SixSixSix succeeds by pairing top-tier animation quality with genuinely high-stakes decision-making, and the numerically fitting 16,666x ceiling is exactly the kind of thoughtful, thematically coherent touch that separates a well-crafted release from a generic reskin. The Wicked Wheels feature gives the game a satisfying, visually distinct centerpiece, and Deal with the Devil's gamble mechanic adds real tension beyond passive spinning. The biggest drawback is undoubtedly the unforgiving nature of its dry spells, and the 14-payline structure means patience and bankroll management are prerequisites rather than conveniences — but for players who embrace that trade-off, this is absolutely worth the spin.
