Introduction
Taking us into the depths of an ancient Egyptian pyramid, Book of Secrets Extra follows an archaeologist as she searches for a magical Golden Book.
We can expect to see scarab beetles, Pharaoh masks, and ankhs as we navigate through the five-reel by three-row game grid, which offers 10 paylines.
This game is a follow-up to the many other Book of Secrets slots from SYNOT, including Book of Secrets Dice and Book of Secrets 6.
It retains much of the same look and layout and most of the same bonus features as the other games, including free spins with a special expanding symbol, but reduces the top prize available.
This game was released in November 2022 so you can read our hot off-the-press Book of Secrets Extra slot review to find out more.

Book of Secrets Extra RTP and Variance

Top Ancient Egypt Slots
Min & Max Bets + Top Wins
Bets in Book of Secrets Extra can start as low as 0.10 and go up to 1 at online casinos like Slots Temple. As free slot staking ranges go, it’s not the largest assortment out there.
There are ten symbols in the game offering a mixture of payouts. The lowest prizes come from playing card symbols, which give you between 0.15x and 15x the stake.
The higher paying symbols are represented by ancient Egyptian artifacts including green scarab beetles and golden Pharaoh masks, and these will give you prizes between 0.5x and 200x. The highest wins in the whole game come from the archaeologist, who pays out between 1x and 500x the bet.
The top win in the game is 500x, which is on the smaller side for free slot top jackpots, compared to something like the potential 20,000x top win in the Jammin Jars slot from Push Gaming.
Book of Secrets Extra Free Spins and Bonus Features
Book of Secrets Extra has a decent selection of bonus features.
As well as free spins, and a comprehensive gamble feature, the Golden Book of the title acts as both the game’s scatter and wild symbol. It can substitute for other base game tiles and has its own payout attached, between 2x and 200x the bet.

The free spins bonus is triggered by landing three of the Golden Book scatter symbols, giving you ten free goes. Before the round starts, a random symbol will be chosen to act as an expanding tile during the round. If this special symbol appears on the grid, then it will expand to fill the whole reel it’s on, giving you lots more winning lines. This symbol can also retrigger the free spins round.
