About this Slot
Asylum 13 is a horror-themed slot from Nocap Labs with an RTP of 96.7%, high volatility and a maximum win of 66,666x. The game plays across 5 reels, 5 rows and 15 paylines.
Serum Syringe wilds land as full reel wilds and carry multipliers ranging from 2x to 500x. When multiple Syringes appear, their multipliers stack together to boost payouts.
Three scatter symbols trigger the Bonus round, which awards 10 free spins. Four scatters trigger the Super Bonus, also awarding 10 free spins but with Serum Syringe wilds locked in place until the round ends. Free spins do not retrigger during either bonus.
Hunt is a toggle feature costing 3x the bet that increases the frequency of both Bonus and Super Bonus triggers. It can be toggled on or off at any time.
Serum Dose (1) can be purchased at 50x the bet. Serum Dose (2) costs 150x the bet. A direct Bonus buy costs 200x the bet and triggers the free spins round. Super Bonus can be bought at 500x the bet for the enhanced version with locked Syringes. Mystery is also available at 500x the bet, with results unknown before purchase-it awards either the Bonus, Super Bonus or a rare Hidden bonus.
