Catch a Flight Back in Time to Ancient Egypt
The Book of Secrets Extra slot machine is another quaint slot in the Synot Games collection, casting a spotlight in the ever so intriguing ancient Egypt. In this edition, we meet up with a stunning brave archeologist in her quest to uncover the treasures that lie in a maroon-ish Pharaoh’s tomb.
The gorgeous explorer, a pharaoh mask, a green scarab, and an ankh cross are the slot game’s highest-earning symbols whereas the A, K, Q, J, and 10 are the lower-paying icons. Moving on to the specials, the Book of Secrets is both the wild and scatter symbol.
Unlock Mysteries to Land Wins on the Reels
Synot Games’ Book of Secrets Extra online slot is a medium-high variance hitter playable on a 5x3 grid layout with 10 fixed paylines, and a high 96.07% RTP. Launch the title and you’ll have the option of setting your wagers between 0.1 and 20 coins for a shot at the payouts listed below:

Hit Massive Rewards via Secret Special Features
As you play Book of Secrets Extra slot online, your reel spinning exercise in will be juiced up by bonus features such as:
3 or more scatters unlock 10 free spins to let you play Book of Secrets Extra for free with a randomly selectedn of special symbol from the standard characters. Whenever you earn a win, the special symbol may expand to cover the entire grid and will pay you out irrespective of the positions it occupies on the grid.
If your win in a spin doesn’t exceed 125,000 coins, then you will be eligible to play the gamble feature if you like. Guess the correct color of the next face-down card to double your initial win, and you risk the new payout again up to 10 more times. However, an incorrect guess leaves you empty handed.
If you aren’t down to collecting scattered wild icons to trigger the free spins organically, the Buy Feature is the shortcut your need. Spend 100x your stake (up to 200 coins max) for direct entry into the 10 free spins. However, only non-UK players can experience this feature due to their gaming regulations.
