If you like Indiana Jones and the type of adventures that he usually gets involved in, then you should probably check this game. Crystal Book is an online slot game developed by spearhead Studios with an exploration theme and it takes place in Egypt. There are nice visuals in this slot including shiny icons in vivid colors, dark reels, and a view of an Egyptian temple loaded with crystals in the background.

Crystal Book comes with 5 reels and has 10 paylines. In this online slot, players will find five colorful playing card icons, a golden ankh, the eye of Horus, a scarab, and Percy Fawcett (the explorer), all used as standard symbols. Of course, there’s a special symbol too – a blue crystal book. This book serves as a wild icon that has the power to replace any symbol in this game when it can help you complete a winning combination. The same symbol acts as a Scatter icon. Land three or more of them on the reels to activate Free Spins. During free spins, one of the standard symbols is turned into an expanding symbol while wild scatter icons bring win multipliers. They also expand and cover reels.
