Book of the Sphinx Slot Review

How to play

The Book of the Sphinx slot uses a typical gaming structure of five reels and three rows with a pretty cheap gaming process. All you need to do is choose a line bet value anywhere from 0.01 to 5.00, and press play! Consequently, choosing your line bet will change your total bet values between 19 levels from €0.02 to €100. Clearly, even the high-rollers can enjoy gambling this title without being too generous.

Afterward, you can opt to take your trip manually by clicking the “Spin” button before each round. Alternatively, you can also use the auto-play option for up to 50 continuous yet customizable plays. However, it's worth noting that the auto spin feature is available in selected jurisdictions only. While playing, your aim should be matching three or more symbols from left to right across any of the 20 paylines for a win as per the paytable.

Symbols and payouts

If you’ve previously played other Egyptian-based video slot machines, then you’ll certainly get familiar with the symbols in the Book of the Sphinx slot. It puts to use eleven icons, categorized into low, medium, and high value. The lowest-ranking values include poker playing cards tens to queens. Collecting three to five of a kind will remit payouts worth 5 to 80 times the line bet. Next up, five of the playing card royals kings and aces will payout up to 100x, while the clay table and golden cobra images reward up to 150x your bet per line.

The big-value icons include pictures of the ankh cross, the Anubis statue, and the scarab. Again, matching three to five on a payline will reward wins from 20 to 500 times your line stake. However, the Pharaoh statue is the highest-paying, giving out prizes up to a decent 2,500x your line stake for five on a line. So, it should be the regular image you hope to land more of during your sessions.

Also, have in mind that besides the regular symbols, you’ll come across additional characters. The Book wild will replace all other icons except the scatter for better winning chances. On the other hand, the Eye of Ra will trigger an in-game feature.

Best Book of the Sphinx bonus feature

All the splendor of this slot comes to life here, promising you some flashy returns. First, keep an eye out for the Eye of Ra as three or more of these on any reel position will activate a special feature. During the feature, the triggering icons will convert into a randomly picked symbol except the wild. The randomly selected icon will expand to substitute for all symbols on the reels they appear. It will then payout for three to five of a kind on any active winning line regardless of the reel position.

In this slot, a Book wild activates the Book of the Sphinx free spins mode, which is quite unusual. Three or more of these symbols appearing in any of the reel positions, will present 10 to 30 bonus games. At the beginning of the feature, one of any of the symbols, except the wild, becomes a special character for the entire round. At least three of the chosen specials land and expand anywhere on the wheels to replace all characters for winning combos. These formations pay in any direction. 

Fortunately, this complimentary round can retrigger when a minimum of three Books appear on the reels during the extra session, potentially reaching up to a max of 250 retriggers per bonus.

RTP & Volatility

The top 96.24% Book of the Sphinx RTP comes in slightly above the average slot machine return to player. But, with a high RTP, players will experience some huge yet less frequent payouts. Nevertheless, the diverse betting limit means you can gamble with a lower stake to limit potential losses.
