How the Game Plays

Book of Ruby, developed by Retro Gaming (a studio powered by Spinomenal), presents a sparkling take on the classic "Book of" genre. The game features a slightly larger-than-average grid of five reels and four rows, set against a backdrop of deep crimson and ancient manuscripts. The symbols are a mix of traditional royal icons and high-value gemstones, with the titular ruby-encrusted book serving as the centerpiece. This symbol is multifunctional, acting as both the Wild to substitute for other symbols and the Scatter to trigger the bonus round.

Free Spins Explained

Landing three or more Book symbols anywhere on the reels triggers the Free Spins mode. Before the round begins, the game randomly selects one standard symbol to become the "Special Expanding Symbol." During the feature, after any initial wins are paid, this special symbol will expand to cover its entire reel if it results in a winning combination. These symbols pay even on non-adjacent reels, provided they land on an active payline.

Retro Bet Explained

A standout mechanic in this title is the Retro Bet feature, which players can toggle on or off during the base game. When activated, the feature doubles the current stake in exchange for a win multiplier ranging from 1x to 10x. This multiplier is applied to every winning combination formed during that spin, offering a way to increase potential returns without altering the core paytable values.
