Book of Ra™ by Greentube is a 5-reel, 3-row slot with 9 paylines and an Ancient Egypt explorer theme. The game uses stylised card symbols alongside themed icons such as a scarab, pharaoh, artefacts and the Book of Ra symbol. Its listed RTP is 94.26%, with high volatility and bets ranging from 0.02 to 18.00.
The demo version allows players to play for free and practice before playing for real money. The main feature is the free games round, which is triggered by scatter symbols and awards 10 free spins in the version shown. At the start of the feature, one symbol is chosen as an expanding symbol, able to cover up to three positions on a reel and form wins across paylines.
Book of Ra also includes a gamble feature after wins, where the result can be risked on a red or black card guess to increase the payout. Win lines are shown clearly on the grid, while autoplay and bet controls are presented below the reels for quick session setup.
