"What creature, having the same voice, becomes alternately four-legged, two-legged, and three-legged?"- this question was asked by the Sphinx, who guarded the ancient Greek city of Thebes, to potential visitors. Those who answered correctly - “the human” - were allowed into the city, and those who were mistaken were killed. Fortunately, Red Tiger's "Riddle of the Sphinx '' is not that hard, and this slot is not about Greece at all. It refers to the Egyptians who had their Sphinx. The playing field with 5 reels in 4 rows, set in the middle of 2 pyramids with golden tips, offers you to make prize combinations in 20 ways, activate bonus features, and win up to 8,000x the stake.

RTP & Volatility

Due to the high volatility, the slot can cover you with a sandstorm or reward you with a large prize at any time, and you should be prepared for this. RTP 94.72% is slightly below the market average.

Riddle of The Sphinx Bonus Features

8.2 

Game Symbols

Values of high standard symbols: Scarab - up to 1,000x, Eye of Horus - up to 500x, Purple brooch - up to 400x, Ankh - up to 300x. The suits of playing cards have become low symbols: Ace pays up to 200x, King pays up to 160x, Queen pays up to 300x, Jack pays up to 100x and 10 pays up to 80x.

Bonus Rounds & Free Spins

Win 3 Scatter on reels 1, 3, and 5 in 1 spin, and the slot will trigger the Pharaoh free spins bonus round. When the Pharaoh symbol is dropped, it will lock in place for the next spin. All new Scatter will also be captured. A multiplier will be added to Wilds and any payline.

Before starting the feature, you have to choose 1 of 4 free spins options. These options differ in the number of free spins and multiplier values. The first 3 have 6, 12, or 24 free spins and multipliers of 8x, 4x, or 2x.

Option 4 is mysterious as it awards any combination of the aforementioned free spins and multiplier.

Riddle Of The Sphinx - Bonus Features

Overall Rating

9.2
Now in the collection of the provider Red Tiger, there are several slots on the Egyptian theme. Their Egyptian games are often easy to forget, with a few exceptions. It's a shame, but Riddle of The Sphinx seems doomed to become another one-off title. The gameplay here is quite fun, the potential is good, and the bonus features are decent, but the presentation is very weak, and if you do not achieve the maximum win, then you will hardly remember this slot after completing the first session.
