This is a classic slot by MainamaGames, where you can see Egypt gods, gold scarabs and many other symbols.
The Sphinx is a wild in this game. It substitutes for all the other symbols in winning combinations except a pyramid symbol and doubles your win. The pyramid is a scatter. 3, 4 or 5 pyramid symbols give you a bonus game that is 10, 15 or even 30 free spins respectively.
