Puzzles people mix up with Meowdoku

Search keeps sliding from Meowdoku into sudoku, Woodoku, Catdoku, and Miaudoku. I split those into three pages so each question has one answer.

• Meowdoku and sudoku — same deduction mood, different objects.
• Meowdoku and Woodoku — one is placement logic, the other is dropping blocks.
• Other cat sudoku apps — names I saw on the store search pages.

If you only need to know which install these level notes follow, start at versions.
