RTP Book of Sherlock is a 5-reel slot from PopOK Gaming with 10 paylines and an RTP of 96.09%. The game uses a high-volatility format and a stake range from EUR 0.02 to EUR 25. Set in a Sherlock Holmes-style London backdrop, it combines classic slot play with mystery-themed features.
The Book symbol acts as both Wild and Scatter. Landing three or more Book symbols triggers 10 Free Spins, where a Special Expanding Symbol is selected before the round begins. During the feature, that symbol expands across the reels and also pays as a Scatter when it appears, while Free Spins can be retriggered.
Players can also collect Clues to unlock Bonus Spins, and the game lists a maximum win of up to 5000x the bet. This demo version lets players play for free and practice before playing for real money while reviewing the rules, payline structure, and bonus mechanics.
