Book of Inferno is a 10-line game with expanding pay anywhere symbols. A symbol is Marked to expand and pay anywhere. Any Book landing will upgrade the Marked symbol one step. A symbol is always Marked at the start of Free Spins. A symbol can become Marked at random in any spin in the base game.
Theoretical payout is 94.19%.
Book symbols substitute for all other symbols.
3 or more Books award Free Spins.
All the reels can have Book symbols.
Sometimes, a random symbol will be selected as the Marked symbol.
Any time a Marked symbol lands, if there are enough of them to pay: the Marked symbols are expanded to cover their entire reel and pay anywhere on a line without the need to be in sequence from left to right in an extra win evaluation.
Any Book symbol that lands together with Marked symbols upgrades the Marked symbols one step, potentially creating new Marked symbols and new expansions.
If the Marked symbol is upgraded past the highest symbol, the lowest symbol that has not yet been converted will be converted into the highest symbol.
In any spin there is a chance a random symbol will become Marked.
You can re-trigger Free Spins by landing 3+ Book symbols and this awards the same amount of Free Spins as stated above.
At the start of Free Spins, a random symbol is selected as the Marked symbol for that session.
The marked symbol can be updated by landing Book symbols. At the start of each spin, the Marked symbol is reset to the initial symbol.
3 or more Book symbols will award new Free Spins as well as upgrade the Marked symbol.
The Free Spins feature continues until there are no Free Spins left.
