About this Slot
Secret Book is an Ancient Egypt, Crime and Sci-Fi themed slot from Tilt Room Games with an RTP of 94.14%, high volatility and a maximum win of 25,000x. The game plays across 5 reels, 4 rows and 16,807 Ways to win.
A Chosen Symbol is randomly selected each spin and displayed beside the reels for reference. Three or more of the Chosen Symbol anywhere on the reels opens and fills those reels completely, increasing the number of ways to win and payouts through the expanded positions.
The Expanding Reels feature adds one row to a reel, with a maximum of seven rows possible. In the base game, an extra row remains for one spin only. During Free Spins, any extra row added becomes permanent for the duration of the feature.
Three or more book Scatter symbols trigger 8 Free Spins. Four books trigger the Super tier of Free Spins, while five books trigger the Hidden tier. Reel growth achieved during the feature stays permanent throughout Free Spins. Each reel that reaches seven rows awards an additional 2 Free Spins once per feature. Reels can chain and expand during Free Spins, potentially triggering further row additions.
A feature buy option is available, allowing direct access to the Free Spins round.
