Book of Ra™

Book of Ra by Greentube is a 5-reel, 9-payline slot built around an Ancient Egypt explorer theme. The game uses a high-contrast layout with card symbols, Egyptian icons, and a Book of Ra symbol that plays a central role in the rules. Reported RTP is 92.13%, and the volatility is high, which means outcomes may vary across longer sessions.

In the demo version, players can play for free and practice before playing for real money. The main feature is the Free Games round, triggered by scatter symbols, where a randomly selected expanding symbol can cover multiple positions on the reel and help form wins across active paylines. Winning combinations are marked clearly on the grid, making the payline structure easy to follow.

After a win, the gamble feature gives an option to risk the result on a red or black card guess to double it. Bet settings run from 0.01 to 18, with autoplay also shown in the interface. The combination of base-game line wins, scatter-triggered free spins, and the expanding symbol defines the slot’s core gameplay.
