Book of Ra

Greentube presents Book of Ra as the title that opened the series: an Egypt-themed slot with 5 reels, 9 paylines and free spins built around an expanding symbol.

In the base game a win needs 5 matching symbols on a payline. Each combination starts on the left and runs to the right, and the symbols have to sit next to each other with no gap. The book, the joker, stands in for every symbol. Three or more books start 10 free spins. Before the round, one special symbol is picked at random as the expanding symbol. If it lands 2, 3, 4 or 5 times, the bonus-symbol value is multiplied by the number of paylines. Greentube lists volatility 5, Egypt and mythology themes, NovoSDK, and play on desktop and mobile.
