Thermal Pantry, the 4×4 fridge puzzle

Why it surfaced

Every swap changes the temperature around its direct neighbours, turning an ordinary fridge into a carefully constrained little strategy board. The site gives the idea an unusually complete presentation, with four temperature families, named visitors, gameplay guidance, and alternate shelf appearances.

A food-swapping puzzle where players rearrange a shared 4×4 shelf, manage temperature, and fulfil visitors’ exact orders.
