Packle

Each day presents a shape alongside a single reference circle for scale. The task is to estimate exactly how many circles of that size can be packed inside without overlapping. Five tries are allowed, and each wrong number receives a temperature rating from Ice Cold to Boiling depending on how far it is from the answer.
