Three yards
Open Catdoku, Dogdoku, or Squirreldoku from one door. Each keeps its own boards and progress.
Doku is Catdoku, Dogdoku, and Squirreldoku in one yard.
Pick a yard. The rules do not change: one per row, column, and colour, and nobody touching.
The three games are also listed on their own if you only want cats, only dogs, or only squirrels.
