Fusion of sun and pastel colorous

The Book of Atem Wow Pot has a maximum win of 5,000 times your stake per spin. This value doesn’t change if you’re playing with free spins or respins, which is a great chance to win.

Follow the Pharaon symbol if you want to get the best stake. The Book of Atem is the wild and has the power to act as a scatter and substitute. This will bring you free spins and one of the two bonus features. So, if the Book symbol lands anywhere on your reels, it is a good sign.

Besides gathering more than three Books, a random symbol can expand and cover the reel. The higher the symbol’s value, the better the chances of getting real money from this jackpot.
