Dr. Cranko's Lab

Yggdrasil presents Dr. Cranko's Lab, a video slot that immerses players in a mad-scientist laboratory filled with neon green bolts, bubbling potions, and chaotic experiments. The game features a 5-reel, 3-row layout with 20 fixed paylines, and players have the opportunity to add a sixth reel to enhance their winning combinations. Utilizing an Avalanche mechanic, winning symbols vanish, allowing new ones to cascade into their place, with each consecutive Avalanche increasing a win multiplier up to a certain limit. On spins that do not result in a win, two random modifiers may activate: a Sticky Wild Respin, which places a sticky wild on reels 2-5 and grants respins, or a Low Transform feature that eliminates low-value symbols while upgrading others. Landing 3, 4, or 5 Scatters triggers Free Spins, awarding 5, 7, or 10 spins respectively, all enhanced with boosted Avalanche multipliers. Additionally, players can enter a Super Free Spins mode by collecting points from Scatters to fill a meter; once full, the next Free Spins awarded become Super Free Spins with even greater multiplier levels. A Bonus Buy option is also available, allowing players to directly purchase Free Spins or Super Free Spins for a cost that corresponds to their stake. With high volatility, the game offers a rich array of features that interact, leading to potentially significant outcomes through cascading wins, expanding reels, symbol transformations, and sticky Wild respins.
