Page updated July 2026
Beat the Beast: Mighty Sphinx is the second entry in Thunderkick's ongoing Beat the Beast series, a collection the studio has built around pitting players against a different mythical creature in each release. After sending players beneath the waves to face a many-armed sea monster in the series opener, Mighty Sphinx swaps the ocean depths for the heat and sand of Ancient Egypt, one of the most well-worn but reliably popular settings in the slots world.
Structurally, Mighty Sphinx sticks closely to the template set by its predecessor — the same 5-reel, 3-row grid, the same 9 fixed paylines, and the same betting range from 0.10 up to 100 per spin. What's changed is the dressing: an Egyptian colour palette and symbol set replace the underwater theming, though the overall visual polish and layout will feel instantly familiar to anyone who's played the first game in the series. It's a sensible approach for a series entry, prioritising consistency over reinvention.
The paytable follows a clear low-medium-high structure. Card royals from 10 to Ace fill the low end, while a Sphinx statuette, scarab beetle, Ankh, and Khopesh sword occupy the middle tier. At the top sits the winged Sphinx herself, worth 250x stake for five in a row — a genuinely strong single-symbol payout, even if it comes in below the standard set by the series' debut monster. Low pays need three symbols to form a win, while medium and high pays need just two, making the premium end of the paytable considerably easier to hit. A Sphinx Emblem symbol pulls double duty as both scatter and wild, substituting for any regular symbol.
Mighty Sphinx carries a high volatility rating alongside a 96.1% RTP, a very slight improvement on its predecessor's return. No official hit frequency figure has been published for this title, so the high volatility rating is the clearest available signal that wins, particularly bigger ones, come at irregular intervals rather than a steady drip.
The maximum win sits at 4,444x the triggering stake, a solid figure that, while lower than some of the more extreme ceilings in Thunderkick's wider catalogue, still gives the high-volatility structure genuine teeth when the Sphinx Emblem lines up favourably.
Beat the Beast: Mighty Sphinx plays it safe by sticking closely to a proven format, trading the series' initial novelty for consistency and a marginally improved RTP. It's a solid pick for players who enjoyed the series opener and want more of the same wrapped in Egyptian styling.
