The Riddle of the Sphinx RTP is 95.66% which is a little on the low side. High variance, the bigger wins will come in the free spins due to the multiplier wilds. The most you can win from a single spin here is 8,002 x your total stake.

Theme – Audio & Design Features – a lavish trip to the desert

riddle-of-the-sphinx-slot-base-game

With an ancient Egyptian theme, there’s a rather opulent feel to the design of the Riddle of the Sphinx slot. The reels are set against a backdrop of purple skies, desert sands and mighty pyramids.

There’s a rather haunting backing track playing while you spin which gives a hint of ancient Egypt. The sound and visuals complement each other rather nicely.

On the regal purple reels, you’ll find A to 10 royals alongside Egyptian hieroglyphs that include an ankh cross and the Eye of Horus. The most rewarding symbol is the scarab beetle. Land 2, 3, 4 or 5 of these on a payline for a payout of 0.5, 5, 10 or 50 x your total stake. There are also wild and scatter symbols. The symbols here are dripping in gold which is just what you’d expect from a slot with this theme.

The bright, lavish design works especially well when you’re playing on a small-screen tablet or mobile device. The straightforward gameplay is also well suited to smartphone play. We have no complaints about the Riddle of the Sphinx mobile slot.

Riddle of the Sphinx Bonus Features

The range of extras on offer in Riddle of the Sphinx isn’t enormous but that limited range of extras can still pack a pretty hefty payout punch. With 2 bonus features, gameplay highlights include special Dynasty Wilds and a free spins round complete with multiplier wilds.

Dynasty Wilds feature

The Pharaoh’s burial mask is the 1×2 Dynasty Wild. Whenever this symbol lands, the Dynasty Wilds feature is activated. All the symbols directly adjacent to the dynasty wild also turn wild. If the Dynasty Wild falls nicely, you could end up with a massive 3×4 block of wilds which can deliver payouts to match.

Pharaoh Free Spins feature

To trigger the Pharaoh Free Spins feature, you’ll need to land scatters on reels 1, 3 and 5 on the same spin. If you land a scatter symbol but you don’t trigger the bonus, the scatter locks in place for the following spin to boost your chances of landing the feature. Once triggered, you’ll be offered the pick of the following free spin and wild multiplier combinations.

  • 6 free spins with 8x multiplier wild
  • 12 free spins with 4x multiplier wild
  • 24 free spins with 2x multiplier wild

Alternatively, you could chance your arm and go for the Mystery Option. This can award any combination of free spins and multiplier wilds. If you’re lucky you could end up with 24 free spins with an 8x wild multiplier. If you’re out of luck, you could end up with the minimum 6 free spins with the lowest 2x wild multiplier.

You can expect to land the Dynasty Wilds more often in the free spins round than in the base game. Just like the base game, they expand to turn all adjacent positions wild. Add the multipliers into the mix and these are potentially very useful.

Riddle of the Sphinx Review Summary – all about the free spins

Delivering gameplay that offers something a little different from the norm isn’t easy when there are so many slots with a similar theme already available. Red Tiger Gaming has done a pretty decent job with the Riddle of the Sphinx slot.

The spreading Dynasty wilds are a decent addition. Especially during the free spins feature when they come with multipliers attached. The ability to choose a free spin and wild multiplier combination in the free spins too is another good addition. I would always opt for the highest multiplier as just 1 free spin could lead to big payouts.

With 8,002 x stake wins possible, this is another simple ancient Egyptian adventure. Other options include the Pharaoh’s Fortune slot by IGT which is a land-based and online favourite. It comes with 10,000 x stake wins, a high RTP of 96.53% and features the ‘Walk Like an Egyptian’ song by The Bangles. If you want something simpler, you cannot go wrong with Book of Dead from Play ‘n GO which comes with 5,000 x stake wins and special expanding symbols in the free spins.
