About Book of Sun
Book of Sun takes you to an ancient Egyptian theme with a book symbol at its heart. Land three or more book symbols and the game enters a free spin mode where one regular symbol becomes extra large and expands across entire reels. This expansion mechanic creates multiple winning opportunities during the bonus rounds. You can adjust your bet amount before each spin, and the game runs across five reels with ten fixed paylines. The paytable shows what each symbol combination pays out, so you can see the potential returns before wagering.
