Book of the Sphinx Bonus Features

Although not overflowing with bonus features, Book of the Sphinx has enough going on to keep most slot players happy for a while. From the Eye of Ra feature to a quality free spins bonus, we are going to delve into the details of the game right here.

Scatter and Wild Symbols

The wild is represented by the game’s namesake, the leatherbound Book of the Sphinx. It will substitute for all symbols except the Eye of Ra and so acts as both scatter and the wild here.

Eye of Ra Feature

Landing 3 or more Eye of Ra symbols anywhere on the reels will trigger this unique feature from the base game. Each Eye of Ra symbol is randomly substituted with any other symbols, excluding the Book of Sphinx, which will then expand to cover the entire reel. It pays out for 3, 4 or 5 of a kind on any payline regardless of the reel position.

Free Spins

The exciting free spins feature is triggered by landing 3 or more Book of the Sphinx symbols on a single spin. Landing 3, 4 or 5 book symbols will get you 10, 15 or 30 free spins respectively.

One special symbol is randomly selected at the start of the free spins feature. If this symbol lands during the free spins round it will expand to cover the entire reel and form winning combinations on active paylines.

Book of the Sphinx Jackpot

Although there is no dedicated Book of the Sphinx in game jackpot, the max win of 2,500x your bet could land a nice win.

RTP and Volatility

With an RTP of 96.24%, Book of the Sphinx comes in just above the slot game average RTP, which is a real boost for players. However, the Book of the Sphinx volatility here is rated as high, meaning that whilst there could be some big payouts, they will be less frequent it seems.

Bonus Spins

If you want to check out the HTML5 update to this game without depleting your casino bankroll then consider using some Book of the Sphinx bonus spins instead. Our friends at Leo Vegas online casino and the entertaining Spinit are both offering bonus spins as part of their casino welcome package right now.
