I stopped calling any single listing “the original.” I do not have a public filing that proves which developer used the name first. What I can do is say which product these answers describe.
The game these level pages follow
Oakever Games. Android title Meowdoku: Brain Puzzle Games, package com.oakever.meowdoku, 10,000,000+ installs, rating 4.7 from 382,843 reviews when I checked. iOS title Meowdoku!, seller OAKEVER GAMES PTE. LTD., id 6761760135, version 1.18.0. The rule text matches: one cat per colored region, no shared row or column, no touching, three hearts.
Other listings I opened
- Grove 42, Meowdoku: Cat Sudoku,
com.grove42.meowdoku. Cat tokens on a sudoku, daily challenge, light and dark mode, about 1,000+ installs. Different rules. - Microsoft Store 9P5ZB339NZRP, Iron Cloud Studio, “Meowdoku : Brain Puzzle Online,” version string 2026.9.28.286.
- Yandex Games meowdoku-537825, developer DRA.
- itch.io page by GameStrategyHub, which labels the project AI assisted and points at another browser game.
Level coordinates on this site were copied from public walkthroughs aimed at the region-and-cat puzzle, not the Grove 42 sudoku. If your app asks for digits, you are in the other game. More name-alikes are on cat sudoku games.
