How to play

Crittermino is a Fillomino puzzle. The givens are the cells that already have an animal. They cannot be changed. Everything else is yours to place, and the solution is unique.

• Fill the whole grid

  Every cell becomes part of an animal home. Empty cells are still waiting for a critter.

• Match the size

  Mouse homes are 2 cells, Cat 3, Dog 4, Panda 5, and Lion 6. The home can bend, but it must be connected edge to edge.

• Same sizes stay apart

  Two homes of the same size cannot share a wall. Touching at a corner is fine. If you join them, the home gets too big and shakes.
