Jackpot Lab welcomes players into a quirky, bubbling laboratory where a mad scientist concocts volatile potions and powerful jackpots. Set on a 5x3 grid with 25 fixed paylines, this slot features animated flasks, beakers, and glowing symbols, creating an engaging scientific atmosphere. The game's main attraction is the "Jackpot Respins" feature, a Hold and Win mechanic triggered by special bonus symbols. Players aim to collect more bonus symbols during respins to win instant cash prizes or one of four lucrative fixed jackpots, including the grand prize for an experimental breakthrough.
