A minute at the cocoa counter
  1. Mugs are fixed. Place marshmallows on other squares. Edge-touching mallows form a cluster; diagonal touching does not join them.
  2. A mug’s number equals the total size of every cluster sharing an edge with it. Count each whole cluster once, even when it curls around the mug.
  3. There is no other rule: separate clusters and solid 2×2 blocks are allowed. A 0 mug touches no marshmallows. A cluster can count for several mugs.

Blank squares can stay blank when you finish. Empty dots are notes, not extra requirements. Try Inspect whenever two groups join—the total can change for mugs far away.
