Book Of Ruby Slot by Retro Gaming

Overview

Would you like to browse a unique book inspired by a gemstone? Book Of Ruby is an online slot game created by Retro Gaming in which a book and many gems play the leading roles. In terms of visuals, you’ll find shiny icons in vivid colors and dark crystal-like reels. Additionally, we have the red background image.

Book Of Ruby is played on 5 reels and has 10 paylines. The game’s paytable includes eight basic symbols: four playing card icons and four gemstones in blue, green, yellow, and red colors. As expected, the slot’s wild icon is in the shape of a book, and it replaces all basic symbols to finish winning patterns. Also, it serves as a scatter icon, and hitting at least three of these books anywhere on the matrix will launch 10 free spins. One of the basic symbols will act as an expanding one during this mode.

Finally, you should not forget that activating the retro bet (side/optional bet) will start the multiplier box that multiplies the wins by one to five times.
