A horrifying new chapter unfolds as Just Slots delivers 500 Casino players a spine-chilling exclusive following the release of Book of Maniac 500
Just Slots, the up-and-coming iGaming content provider, has launched its first-ever dedicated exclusive, Book of Maniac 500, working alongside 500 Casino, bringing a sinister setting and a fresh twist to the classic 'Book of' format to players brave enough to play.
Set across five reels and 10 paylines, the high-volatility release builds on the format's signature expanding symbols and Free Spins with multipliers that increase with every bonus retrigger. The familiar formula takes a darker turn in a deserted campsite setting, with a maximum win potential of 500,000x.
The scares start in the base game, where any spin can trigger a Special Expanding Symbol. A symbol can be randomly selected before the reels stop and is given a multiplier of up to 100x. If the chosen symbol forms a winning combination, it expands to pay across all 10 paylines without needing to land on adjacent reels, with the multiplier applied to its payouts.
Landing three, four or five wild symbols will open the book on 10 Free Spins, with an expanding symbol and starting multiplier selected before the feature begins. Four wilds guarantee a starting multiplier of at least 2x, while five raise that minimum to 10x.
Before entering the feature, players can accept their awarded spins or attempt to improve it through three Gamble Wheels. These offer the chance to upgrade the expanding symbol, starting multiplier or both, although an unsuccessful gamble forfeits the feature and returns play to the base game.
Once Free Spins begin, two or more Wilds award additional spins and add a new multiplier of up to 100x to the existing value, increasing the multiplier applied to expanding symbol wins.
Three themed Bonus Buys, Stalker, Slasher and Maniac, provide direct entry to Free Spins at 150x, 500x and 2,000x the base bet respectively. HotSpin Ember increases the chance of triggering the feature for a total stake of 3x the base bet.
Nick Formosa, Head of Client Strategy at Just Slots, said: "Book of Maniac 500 takes the classic 'Book of' formula somewhere far darker, with a creepy deserted campsite setting and impressive multipliers that build every time Free Spins retrigger there really is a lot to love about this release.
