About this Slot
The Library Overdue is a horror-themed slot from Kitsune Studios with an RTP of 96.28%, high volatility and a maximum win of 10,000x.
Stackways™ fills each reel with stacked symbols holding between two and ten base game symbols. Standard Stackways™ symbols show values of two, three or four. Special symbols expand the stack further when they land in a winning combination.
The Stackways™ Booster symbol increases the minimum stack size. During Stack the Shelves Spins, special symbol expansions reset Booster increases. In Overdue Spins, special symbol expansions do not reset the Booster, allowing Stackways™ Booster increases to persist throughout those free spins.
Stack the Shelves Spins awards ten free spins, during which Stackways™ expands more aggressively than in the base game.
Overdue Spins also awards ten free spins.
Four bonus buy options are available. BonusHunt FeatureSpins™ costs 6x the bet and makes each spin five times more likely to trigger a bonus. Stackways™ FeatureSpins™ costs 100x the bet. Stack the Shelves Spins costs 200x the bet. Overdue Spins costs 600x the bet.
