Book of Ra

Greentube's Book of Ra is one of the originals — released 5 October 2017 and still a reference point for the whole book-slot genre, sitting in a 361-game catalog.

The 5-Reel Book Template

Five reels form the grid. Our feed doesn't carry a fixed payline count, so we won't state one — the book format traditionally uses adjustable lines. The single expanding symbol from the free-spins round is the mechanic that made this style famous. Bets run from 0.02 to 18. No buy feature and no progressive appear in our data.

Reading a 94.26% Return

Return to player is listed at 94.26% from our catalog feed, unverified. That's a notable gap beneath the 96.08% midpoint our 8,699-game sample produces — over a point and a half short of centre. Volatility is 5 of 5, high. A low return paired with heavy swing is the classic book-slot bargain: rare, large free-spin hits fund the long quiet stretches. That trade has kept the format alive since well before this 2017 build.

Who Still Plays the Original Book

This is for players who value the genre's history and the expanding-symbol tension over a competitive RTP. The low 0.02 minimum keeps sessions cheap. But a 94.26% return is a real cost over time, so anyone RTP-conscious should weigh that against the nostalgia. Greentube's 361-game catalog carries higher-return options if the number matters more than heritage.

A 94.26% return leaves the house near 5.7% on average, wider than most, and level-5 variance spreads results thin. Set your limit before playing. 18+.
