Just Slots Launches First Dedicated Exclusive With 500 Casino

Just Slots has launched its first dedicated exclusive title, Book of Maniac 500, in partnership with 500 Casino.

The high-volatility slot features five reels and 10 paylines, combining the traditional expanding symbol and Free Spins mechanics associated with ‘Book of’ titles with multipliers that can increase following bonus retriggers.

Set within a deserted campsite, Book of Maniac 500 offers a maximum win potential of 500,000x.

Expanding Symbols Offer Multipliers Up To 100x

During the base game, any spin can trigger a Special Expanding Symbol.

A symbol is randomly selected before the reels stop and receives a multiplier of up to 100x. If the selected symbol forms a winning combination, it expands to pay across all 10 paylines without needing to appear on adjacent reels, with the multiplier applied to the resulting wins.

Landing three, four or five Wild symbols triggers 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 increase the minimum starting multiplier to 10x.

Before entering Free Spins, players can either accept the awarded feature or attempt to improve it through three Gamble Wheels.

The wheels provide opportunities to upgrade the expanding symbol, starting multiplier or both. An unsuccessful gamble forfeits the feature and returns the player to the base game.

Free Spins Multipliers Increase With Retriggers

During Free Spins, landing two or more Wilds awards additional spins and adds a new multiplier of up to 100x to the existing value.

The accumulated multiplier is then applied to expanding symbol wins for the remainder of the feature.

Three themed Bonus Buy options are also available. Stalker provides direct entry to Free Spins for 150x the base bet, Slasher costs 500x and Maniac is available for 2,000x.

The HotSpin Ember feature can also increase the likelihood of triggering Free Spins 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.

“We are thrilled to be launching this game exclusively with 500 Casino, it gives players a distinctive addition to their lobby and demonstrates how Just Slots can bring our own creative approach to exclusive content. We’re looking forward to seeing their response when the book opens.”

Henrik Bergström, head of casino at 500 Casino, added:

Not only have we got a fantastic new slot in Book of Maniac 500, but we’ve also established a fantastic partnership with a fast-growing studio who will go on to produce even more great games for our players to enjoy.”
