Book of the Sphinx from GTech G2 (BossMedia) is a 5-reel, instant play slot game with up to 20 paylines. Its most notable gameplay feature is the free spin and bet multiplier sequence. A winning combination is comprised of 3 – 5 matching symbols along any of the active paylines. It has 13 unique symbols to make winning combinations, including one scatter/wild symbol that generates free spins, and one scatter symbol that triggers a special bonus symbol feature. Book of the Sphinx lets you into the enigma of the Sphinx, and takes you back in time to Ancient Egypt. A land dripping in gold!
In the free spins and bet multiplier sequence, the Book of the Sphinx symbol substitutes for any other symbol in a winning combination, except the mysterious Eye of Ra symbol. The Book of the Sphinx is also a scatter symbol that generates free spins. Here’s a summary of what you get with this symbol hits the reels:
| Number of Book of the Sphinx Symbols appearing anywhere on the reels | Number of Free Spins | Additional prize when Book of the Sphinx symbols appear as a winning combination |
| 3 | 10 | 2 credits x total bet |
| 4 | 15 | 20 credits x total bet |
| 5 | 30 | 200 credits x total bet |
The Eye of Ra is a key symbol in this game. When three or more Eye of Ra symbols appear anywhere on the reels, you receive a prize for all original winning combinations. If this happens, a special bonus symbol is created from one of the other ordinary symbols on the reels, and it expands to cover all three positions of the reel it appears on. This is a great way to catch those winning combinations.
Betting starts from as low as 0.01, up to 10.00 credits per line, and the best winning combination (5 pharaoh symbols) gives 2,500 credits. Daring players will enjoy the optional Gamble Round. In this round, they have the chance to quadruple part, or their entire prize, up to 5 times in succession! A player wins double the amount gambled if they succeed in correctly guessing the colour of a facedown card, or quadruple the amount gambled if they correctly guess the suit.
The optional Autoplay function allows you time to decipher some hieroglyphics, or stack a few pyramid blocks, while up to 100 spins are generated consecutively based on the same bet. Naturally, you can stop the Autoplay sequence at any time. The Autoplay sequence also pauses to allow you to participate in the Gamble Round.
Book of the Sphinx claims to be a classic slot. Its success in the land-based slot arcades does nothing to taint this image. Our conclusion? This is a fantastic game with captivating gameplay, smooth gaming engine and crystal clear graphics. As always with GTech G2 games, the attention to detail really pays off. For example, the reels quake for a moment in celebration whenever you win a large prize relative to the number of credits bet! We certainly recommend you take Book of the Sphinx for spin.
