Book of Inferno develops Quickspin’s book-slot format with a symbol ladder that can change during a spin. Book of Inferno runs on 5 reels, 3 rows and 10 fixed paylines, with the Book acting as Wild, Scatter and upgrade trigger. Book of Inferno was released on 7 February 2023 and follows Anna the Explorer into an underworld setting.
Book of Inferno arranges six card ranks and four character icons beneath a strip showing their order from lower to higher value. Book of Inferno uses that strip to identify the active Marked Symbol and track any upgrade caused by a Book. Book of Inferno otherwise evaluates regular wins from the first reel across its fixed lines.
Book of Inferno can expand marked icons over full reels when enough copies appear. Book of Inferno then pays those symbols anywhere on a line without requiring a standard left-to-right sequence. Book of Inferno generates the marked choice and all reel positions randomly, so no control setting guarantees the feature.
Book of Inferno has the following verified specifications:
Book of Inferno carries volatility of 7/10 in the Wildz-listed MGA version. Book of Inferno offers a possible maximum of 5,846x the stake and has no progressive jackpot. Book of Inferno configurations and stake options can differ by operator, making the opened game’s information panel the correct place to confirm current conditions.
Book of Inferno begins each paid round after the total wager has been selected and confirmed. Book of Inferno checks ordinary combinations across 10 paylines, with matching symbols normally connecting from the left. Book of Inferno lets the Book substitute for paying symbols and also count towards the bonus trigger.
Book of Inferno performs an additional calculation when the active marked icon appears often enough. Book of Inferno expands each qualifying marked icon and evaluates it anywhere along a line. Book of Inferno does not remember losing spins in a way that makes a feature more likely on the next round.
