Book of Sun: Multichance by Booongo is an Ancient Egypt-themed slot played on a five-reel grid with 10 lines. The base game uses a standard mix of themed symbols and card values, while the Book acts as a wild scatter and can substitute for other symbols except special expanding symbols.
The main feature is the free spins round, triggered by three or more Book symbols. The game awards 12 free spins and adds a special expanding symbol, which can fill an entire reel when enough matching symbols land. Additional Book symbols during free spins can add 12 more spins and unlock more expanding symbols, with up to nine available in total.
This demo version lets players play for free and practice before playing for real money. The review near the launcher highlights the slot’s reel-expansion mechanic, win highlights and bonus round structure, which define the game’s core play style.
