Candy Alchemy Lab is a local recipe-crafting puzzle set on a copper-and-syrup laboratory bench. Players select formulas from the recipe book, swap candy ingredients on the lab grid, build reaction energy with mixer controls, harvest the ingredient garden, and craft results such as Rainbow Serum, Fizzy Frosting and Caramel Tide. Each successful formula consumes the right ingredients, raises the lab level, records flavor discoveries and unlocks later experiments across 18 stages. The focus is on matching ingredients for a recipe, not on generic score clearing, so every round asks players to decide which flavor components to collect and when to craft.
