Rules and Gameplay

The Book of Shai slot machine, launched by RNGPlay in the first quarter of 2023, adheres to the classic formula of slot gaming with a modern twist. Set against the backdrop of ancient Egypt, this game features a standard layout of 5 reels, 3 rows, and 20 fixed paylines. Players can embark on this intriguing adventure with a minimum bet of $0.20, scaling up to a maximum of $20 per spin. High volatility defines the gameplay, offering a thrilling experience with the potential for substantial rewards, underscored by a juicy jackpot worth 10,325 times the player’s bet.

Bonus Features

Book of Shai is replete with exciting bonus features that enhance the gaming experience and increase winning chances:

  • Wilds and Scatters: Wild symbols can substitute for any pay symbols to form winning combinations, while Book Scatters trigger symbol transformations and free spins.
  • Symbol Transformation: Landing a Book Scatter in the base game reveals a pay symbol, transforming its instances into Wilds, thereby improving win potential.
  • Free Spins Feature: Three Book Scatters initiate 8 free spins with a twist. If the scatters reveal matching symbols, players are awarded Expanding Wilds alongside a win multiplier of up to 5x.
  • Buy Feature: For those impatient for action, the Buy Feature allows direct access to the Free Spins round for 100x the current bet.


The symbols in Book of Shai draw heavily from its Egyptian theme, offering a mix of traditional and thematic elements:

  • Low Pay Symbols: Card ranks from Nines to Aces, offering wins up to 2.5x the bet for a full line.
  • High Pay Symbols: Thematic symbols such as ankhs, birds, cats, eyes, and scarabs. Scarabs are the most valuable, with 5 on a payline rewarding 15x the stake.


The payout structure in Book of Shai is dynamic, designed to reward adventurous players with its high volatility. The game’s jackpot stands at an impressive 10,325x the player’s bet, promising substantial payouts. However, the theoretical RTP is a point of contention at 93.93%, slightly below the industry average. Players should approach the game with a balance of caution and optimism, aiming for the big wins the game promises.


Book of Shai features 20 fixed paylines, providing players with numerous opportunities to land winning combinations across the reels. Each spin offers a chance to align symbols according to predefined patterns, essential for unlocking the game’s considerable payouts and bonus features.
