Design & Symbols


If you’ve been awaiting the second in the series the first thing you’ll notice is that Mighty Sphinx looks very similar to Kraken’s lair in terms of board and overall design. Of course, the theme, colors, and some of the symbols have changed, but side by side the similarity is quite substantial.

Rather than the rocky entrance to an underwater lair flanking the gameboard, with shipwrecks in the distance, we now have temple steps, and sand dunes, with pyramids in the distance. And of course, the aquatic blue has been exchanged for the deep yellows and burnt orange of the desert. The gameboard sits front and center with reels carved brownstone. The gameplay is accompanied by a seductive and rhythmic soundtrack befitting the theme.

Low-value symbols are the standard royal card values 10-A. Medium value symbols are Khopesh swords, scarabs, ankh crosses, and gold Sphinx statuettes. High-value symbols are the Winged Sphinx, the Sphinx Emblem scatter/wild, and wild upgrades. The winged sphinx is the highest value regular symbol, paying 250x the bet size for a full payline. The scatter/wilds are the highest paying symbols, awarding 1000x the bet size for 5 on a payline, although note that 5 scatters NOT on a payline only pay 200x.

Special Features

  • Mystery Feature
  • Bonus Game (Free Spins)

Mystery Feature


Before the start of any game up to 3 Sphinx Emblems (which act as both wilds and scatters) may appear anywhere on the reels. This can either trigger the bonus game, or at least increase the likelihood of a win and/or triggering the bonus game.

Bonus Game (Free Spins)

Three or more scatter symbols trigger the bonus game with 10 free spins. Between 1 and 3 Sphinx Emblems appear on the board before every free spin. Three or more scatters landing during the bonus game trigger an extra 5 free spins. A retrigger also turns one of the medium value symbols wild for the remainder of the round. With 4 medium value symbols, this can happen up to 4 times.

Our Thoughts on Beat the Beast – Mighty Sphinx

Mighty Sphinx is by no means a bad game; it fulfills the brief of being a volatile, classic game that will appeal to a wide range of players. However, it is just a little bit too similar to Kraken’s Lair to get overly excited about. It also has a lower max payout at 4,444x rather than 7,777x. This will of course mean that it will pay out more during the base game, but I guess I was hoping for something meatier this time around. This isn’t to say I didn’t have fun playing it, and with the bonus not being especially hard to retrigger, the bonus spins can be quite enjoyable and profitable. Still, I’m hoping for something a little more adventurous from Thunderkick next time.
