How the Game Plays

Lost Book is an Egyptian-themed adventure slot from REDSTONE that follows the classic "Book of" formula. Set against a backdrop of golden sands and ancient stone carvings, the game uses a standard 5x3 grid with 10 fixed paylines. Wins are formed by landing matching symbols from left to right, with high-paying symbols like the intrepid Explorer, sarcophagi, and the Eye of Horus offering substantial rewards. The Book symbol is the most important icon on the reels, as it performs a dual role by substituting for other symbols and acting as the gateway to the bonus round.

Free Spins Explained

Landing three or more Book symbols anywhere on the reels triggers the bonus round, awarding 12 free spins. Before the round begins, a random symbol is chosen to become the Special Expanding symbol. When enough of these chosen symbols land on different reels, they expand to cover the entire column and pay out across all 10 lines, regardless of whether they are on adjacent reels. This mechanic is the primary engine for reaching the game’s top payout potential.

Mystery Jackpots Explained

Beyond the standard reel wins, this title features three tiered progressive jackpots: Diamond, Gold, and Platinum. These mystery awards can trigger randomly during any base game spin. A small percentage of every bet contributes to the pots, which continue to grow until a lucky player hits the randomly determined threshold required to trigger the payout.
