About this Slot
Book of Brew is a fantasy, magic, horror, medieval alchemy slot from Grind Gaming with 5 reels, 5 rows and 15 paylines. It has an RTP of 96%, high volatility and a maximum win of 25,000x bet.
Wilds substitute for all symbols except scatters and carry random multipliers up to x100. When multiple wilds land on a single payline, their multipliers combine before the payout is calculated.
Scatters trigger the bonus round and do not pay directly. Three or four scatters award 8 or 10 free spins respectively. During bonus spins, one cauldron cell is active per spin, spawning 1-4 extra wilds. These extra wilds carry the same multiplier as the wild that triggered them. Three or more scatters landing during the bonus retrigger the round and add 3 free spins.
The Super Bonus round is triggered by landing five scatters and awards 12 free spins. Two cauldron cells are active per spin during the Super Bonus. Retriggers occur with 3 or more scatters and add 3 free spins.
Extra Chance mode costs 2.5x bet and increases the chance of scatters landing. Special Spin costs 200x bet and guarantees a cauldron cell trigger. Max Spin costs 700x bet, activates 2 cauldron cells, guarantees one wild trigger and forces all wilds to display x100 multipliers.
Bonus can be purchased directly for 250x bet. Super Bonus can be purchased directly for 500x bet.
