About Book of Inferno

Book of Inferno puts you in control of a fiery slot experience centered around the classic book mechanic. Land three book symbols and the game hands you free spins where one random symbol expands to fill a whole reel. This happens every spin during the bonus round, which means you can see big patterns form without much waiting around. The base game plays like most five-reel slots, so if you've played one before, you'll recognize the rhythm. The book acts as your ticket to the best payouts, so watch for those scatter hits.
