About this Slot
Midnight Library is a fantasy-themed slot with a magic and medieval aesthetic featuring gems. The game has an RTP of 96.7%, high volatility, and a maximum win of 25,000x.
The game plays across a 6×5 cascading grid where eight or more matching symbols anywhere on the grid create a winning combination. Cascading reels drop winning symbols away, allowing new symbols to fall and create additional wins in a single spin.
Mystery Symbols appear randomly during play and can transform into matching symbols to help form wins. Multipliers increase the value of wins during the cascade sequence.
The Bonus feature awards eight free spins with multipliers of x10 or higher. This bonus can trigger randomly during the base game or be purchased directly.
Bonus Boost doubles the chance of triggering the bonus feature.
The Mystery Bonus randomly selects from three possible bonus outcomes: the standard Bonus, Super Bonus, or Hidden Bonus.
Super Bonus awards ten free spins with multipliers of x50 or higher. This bonus can trigger randomly or be activated through the Mystery Bonus.
Hidden Bonus awards twelve free spins with multipliers of x100 or higher. This bonus can trigger randomly or be activated through the Mystery Bonus.
Multiplier Spin is a buy option that applies a first-cascade multiplier ranging from x50 to x500, though no win is guaranteed on that spin.
Super Multiplier Spin is a buy option that applies a first-cascade multiplier ranging from x100 to x2,000, with no win guarantee.
