Book of the Sphinx Slot Machine

IGT's Book of the Sphinx is a five-reel, twenty-payline slot machine that may be played for 0.20 to 100 per spin on any device. Based in ancient Egypt, it includes an Eye of Ra feature that awards full symbol stacks in the base game and a Free Spins Bonus feature. In the latter, you'll receive up to 250 free spins with growing symbols. The maximum possible win is 2,500 times the wager.

Slot Features

The A, K, Q, J, 10 and 9 card suites are displayed on the reels of Book of the Sphinx, a slot machine with an ancient Egyptian theme. There are also scarab beetles, golden cobras, ankh crosses, statues of Anubis, and clay tables.

The Pharaoh is the most valuable symbol, paying out 2, 12, or 100 times your bet for 3, 4, or 5 on a payline, respectively. All symbols, with the exception of the Eye of Ra and special symbols, can be replaced by The Book (of the Sphinx) (more info below).

When three or more Eye of Ra symbols appear anywhere on the reels, the Eye of Ra feature is triggered. These triggering symbols are then replaced with a symbol selected at random (bar the Book symbol). These randomly selected symbols then expand to cover the entire reel they appear on, resulting in wins regardless of their position on the reels.

Book of the Sphinx also features a Free Spins Bonus, which is activated when three or more Book symbols appear anywhere on the screen. 3, 4, or 5 of them will award you with 10, 15, or 30 free spins and 2, 20, or 200 times your wager. During the feature, 1 symbol (other than the Book symbol) is chosen at random to be the special symbol.

When three or more special symbols emerge during a free spin, they will grow to span the entire reel. Please be aware that only expanded special symbols can create winning combos. You can retrigger the feature by landing three or more Book symbols anywhere on the reels; in fact, you can retrigger the feature multiple times for a total of 250 free spins.

With the Free Spins Bonus feature, it's all about the special symbols; if you get the Pharaoh symbol as the special symbol, you might end up with a screen full of them. In that situation, you would win 2,500 times your wager on one free spin.
