Riddle of the Sphinx Bonus Features

For a game about riddles, things are actually kept nice and simple here. There’s not a whole lot on offer in the way of bonus features in the Riddle of the Sphinx slot, but what is included in slot features can help you to land some generous wins at any time.

Look out for the spreading Dynasty Wilds in both the base game and free spins round, which turn adjacent symbols wild for extra win potential. You’ll also get to choose your favoured mix of spins and multipliers in the Pharaoh Free Spins feature, with a possible 24 spins and 8x multiplier combo.

Dynasty Wilds

A mighty 1×2 sized Pharaoh symbol acts as the wild. Known as the Dynasty Wild feature, these colossal symbols can turn any adjacent symbols wild wherever they land on the reels. This can potentially give you a very handy 3×4 wild block in the base game and especially the free spins feature, where they appear more often.


Scatters are the key to unlocking the Pharaoh Free Spins feature. To achieve this you’ll need to land at least 3 on reels 1, 3 and 5 during the same spin. To assist you in this quest, scatters lock into place for the next spin with any new scatters also locking into place.

Pharaoh Free Spins

Once you’ve landed the necessary scatters to unlock the free spins round, you get to choose one of the following 4 options to play with:

  • 6 free spins with an 8x wild multiplier
  • 12 free spins with a 4x wild multiplier
  • 24 free spins with a 2x wild multiplier
  • Mystery pick – awards a random combination of the above

Going for the mystery option could see you get a lovely 24 free spins combined with an 8x multiplier if you’re lucky. It all depends on how much you want to risk it because the other extreme would give you a measly 6 free spins with a 2x wild multiplier.

Whichever wild multiplier you get will be attached to any win featuring a wild symbol. It’s worth knowing that the multiplier is only applied once per win as, unfortunately, multiple wilds don’t get added together.

Riddle of the Sphinx Jackpot

If you think that solving the riddle will lead you to a jackpot, then you are very much mistaken. That said, the 8,002x your stake potential in this game should more than make up for it.

RTP and Volatility

Just like the alleged temper of the Sphinx herself, this slot is highly volatile. This isn’t great news when paired with the below average RTP of 95.66% here.
