Book of Arcane 100 Slot by Just Slots

Trigger the bonus and the game immediately asks how much you want to risk before a single free spin plays. Three gamble wheels appear: one upgrades your expanding symbol up the paytable, one bumps the multiplier (anywhere from 1x to 100x), and a third gambles both at once. Keep spinning wheels, keep climbing. Lose, and the entire bonus round is forfeited. No spins played, no partial payout. Back to base game. That's a binary bet most Book of games don't ask you to make.

Three buy bonus tiers skip the base game wait at 80x, 250x, and 1,050x. The cheapest tier has no multiplier floor, so you could enter free spins at 1x. The 250x option guarantees at least 2x. At 1,050x you start with a minimum 10x multiplier already locked in. The gamble wheels still appear after every purchase, so bought entry stacks with optional risk on top. During the round itself, the selected symbol expands to fill whole reels vertically whenever it lands, and the multiplier applies to every win that expanded symbol generates. Three more Books retrigger additional spins.

A moonlit castle library frames the grid, enchanted tomes drifting past arched stone windows. The fire mage clutching a glowing orb sits at the top of the paytable (100x for five across all ten lines), followed by an ice sorcerer and a green witch casting emerald spells. Mid-tier symbols are a jeweled hat, gem-encrusted rings, golden scrolls. Royals in ornate fantasy frames handle the low end. Between bonus triggers, a random base game feature occasionally opens a book, assigns a symbol and multiplier, and expands that symbol for the current spin - infrequent, but it breaks up the quiet stretches that ten paylines naturally produce.
