Play Book of Riches Slot Game

If there’s one theme that never runs out of secrets, it’s Ancient Egypt. Book of Riches from RubyPlay takes another expedition into the world of golden treasures, mystical tombs, and, of course, an adventurer who seems to have misplaced his fedora but not his luck. The game sticks to the classic "Book of" formula, where the legendary tome serves as both a wild and a scatter, but it throws in a little extra shimmer with its gold-plated growing symbols — a feature that could potentially turn the reels into a wall of stacked wins.

The slot plays out on a 5x3 grid with 10 paylines, keeping things simple and familiar. The minimum bet starts at 0.10, making it accessible for a wide range of players. If three or more book symbols land, they could trigger 10 free spins, which can be retriggered indefinitely. The game’s growing symbols add a dynamic touch, randomly selecting a symbol that can expand and cover multiple reels, even when they don’t land in traditional paylines.

RubyPlay has a growing catalogue of themed slots that follow similar mechanics. If Book of Riches catches your interest, you might also want to check out Immortal Ways Diamonds or Quest of Riches, both of which explore different narratives while keeping their gameplay on par with Book of Riches.

As expected, the slot's symbols mix classic Egyptian imagery with standard card ranks. Low-paying symbols are familiar 10-A card values, while premium symbols include a sarcophagus, a scarab beetle, a cat statue, and the hero explorer. A complete paytable is given below:

The Book of Riches symbol serves as both a wild and a scatter. As a wild, it substitutes for any symbol to potentially form a winning combination. As a scatter, it triggers the Free Spins round and could offer payouts of up to 200x the total bet for landing five of them in a spin.

Free Spins Bonus

Landing three or more book scatter symbols triggers the Free Spins feature, awarding 10 free spins. This bonus round comes with a randomly selected expanding symbol, which can cover multiple reels when enough of them appear on screen. The free spins can be retriggered by landing additional scatter symbols.

Growing Symbols

One of the game’s standout features is the gold-plated growing symbols. Before each spin, one symbol is chosen at random to become the growing symbol for that round. If enough of these symbols land, they expand to cover their reels, paying from any position rather than following standard paylines.

Book of Riches follows the well-known "Book of" format, giving the audience expanding symbols and free spins, much like other popular Egyptian-themed slots. If you enjoy Book of Riches, you might also like Book of Dead by Play’n GO or Book of Golden Sands by Pragmatic Play, both of which feature similar mechanics with different twists and are available at Heart Bingo.
