Book of Skulls Slot Review

This Spinomenal slot has a fixed 10 payline and pays out winnings from left to right. Book of Skulls offers plenty of opportunities to win. One of these is the free spin round.

The book is The Wild, and it is also the scatter symbol that can turn up anywhere in the main game and expand in the free spins. It substitutes for all other symbols.

Free Spins

Here is your chance to collect the luck and bring it home—land 3 or more scattered Wild symbols anywhere on the play grid to trigger the 10 free spins. The game will present you with a wheel of chance displaying all symbols except the Wild. You have to spin the wheel to determine which symbol will expand the free spin round. Free spins can be retriggered and awarded additional 10 free spins.

During the round, the expanding symbol will expand to form new paylines to the existing ones. However, the symbol will expand only if the expansion results in a winning combination. The expanding symbol will pay accordingly to the paytable in all active lines, no matter whether the symbols of the winning combination are consecutive or not. Thus, the expanded symbols count separately from the original result.

Buy Feature

The buy feature is a practical function that allows players to get into the free spins round without triggering. You only have to tap or click the buy button. It will present you with a new screen where you can modify your bet to play free spins. It will calculate the purchase price, and after you click the Buy button, the game immediately starts. You’ll get a boost to your luck, doubling your chances of winning.
