If you want a Meowdoku alternative, compare the actual rules before the artwork or name. Plainoku is an independent Cat Sudoku experience with Queens-style placement rules: one cat per row, column and irregular color region, with no touching, including diagonals. It is not classic number sudoku and is not affiliated with the games below.
Which Meowdoku alternatives use similar placement rules?
These are specific products or implementations, not a ranking. The comparison distinguishes row, column, region and adjacency rules from platform and play format. Official sources were checked on October 3, 2026; features, availability and monetization may change. We do not claim an unverified price, ad frequency or search-volume figure.

| Game and exact version | Rule match | Platform | Play format |
|---|---|---|---|
| Miaudoku | One cat per row, column and color region; cats cannot touch, including diagonals | Browser; installable PWA with offline play | Daily and custom puzzles, hints, Auto-X, a scored 20-level run and endless play |
| Catdoku! Cat Logic Puzzles — Redeye Game | The same one-cat placement and no-touching constraints | iPhone and iPad app | Main progression playable offline, daily puzzles and board-size levels, hints and hearts |
| Queenzle — Honey Badger | One crown per row, column and color region; no touching crowns | Android; also iPhone and iPad | Campaign puzzles; a browser-playable version was not verified |
| Star Battle — puzzle-star-battle.com | One-star mode matches the placement count; two-star mode needs two stars in every row, column and region | Browser implementation | Selectable puzzle formats; rules depend on the star count and whether regions are present |
| Queens — LinkedIn | One crown per row, column and color region; no touching, including corners | Web and LinkedIn mobile app | One daily puzzle; an older puzzle expires when the next day’s becomes available |
How do Miaudoku and Catdoku differ from Plainoku?
Miaudoku’s browser Help describes the matching placement rules. Its custom puzzles, Auto-X notes and scored run offer formats beyond Plainoku’s manual notes and five size categories. We have not established a blanket advertising or account policy for Miaudoku, so its browser availability should not be read as a promise of ad-free or permanently anonymous access. It is distinct from similarly named number-sudoku products.
The Catdoku entry above refers only to Catdoku! Cat Logic Puzzles by Redeye Game on Apple’s store. The official listing identifies advertising, in-app purchases and a Remove Ads option. Other Catdoku apps, portal games and developer versions are separate products; their pricing or features cannot be merged into this listing. Use the linked developer and app identity when deciding which version to install.
Are Queenzle and LinkedIn Queens chess puzzles?
These games use crowns and Queens-style placement constraints, but their no-touching rule is not an international-chess rule about attacking along an entire diagonal. Distant diagonal crowns are not excluded merely for sharing that diagonal. Queenzle’s official stores list advertising and in-app purchases. LinkedIn’s Queens rules and games FAQ describe its daily format and member play; we do not claim that every guest must log in or that it is ad-free.
When is Star Battle a useful cat-puzzle alternative?
Star Battle is a puzzle category, and the linked site is one web implementation. Check the selected star count before applying Plainoku habits. A two-star puzzle requires two stars, not one, in every row, column and region, while stars still cannot touch. More-star variants use the count shown. Shapeless mode removes the color-region condition. The site includes Remove Ads and Report This Ad controls; that does not tell us how frequently any particular player sees advertising.
What does Sudoku Without Ads offer instead?
Plainoku offers free browser puzzles and hints with no advertising or account flow, manual exclusion marks, keyboard navigation and five board sizes from 5 × 5 to 9 × 9. These sizes are not calibrated logical difficulty ratings. Its fixed daily is 6 × 6, with local completion deduplication and a daily streak. Hints reveal an answer position rather than explaining a deduction. Progress stays in the current browser rather than syncing through an account.
Choose based on the rules and format you want: an app campaign, a browser run, a daily crown puzzle, a multi-star challenge or a quiet practice board. Play Plainoku Cat Sudoku without ads, read the placement rules, or check what a free download means. We do not promise that any third-party alternative has the same policies as Plainoku.
