Pros
Low volatility, frequent wins
RTP of around 96.8%
Simple rules
Cons
Few features beyond free spins
Smaller top wins

Book of Sun is Booongo’s Egyptian book slot, tuned for frequent small wins rather than big swings. It keeps the rules simple and pairs them with a good RTP.

How Book of Sun Plays

Five reels, three rows and 10 paylines. Some high symbols pay for just two in a row, which helps keep wins coming between bonuses.

Features and Bonus Rounds

  • Book wild/scatter – pays anywhere and triggers the bonus.

  • Free spins – three or more books start a batch of free spins.

  • Retriggers – more books during the round add spins.

RTP, Volatility and Max Win

Book of Sun has an RTP of about 96.8%. This is in line with or slightly above the industry average. RTP is a long-term average over millions of spins, not a guide to any single session.

Low volatility means frequent, smaller wins and a smoother ride – good for longer sessions and bonus wagering.

Our Verdict

A relaxed book slot for longer sessions. Low volatility and an RTP of around 96.8% make it a good choice for bonus wagering, though big wins are rarer than in high-volatility book games.
