Choose by the kind of reasoning you enjoy
| Game | Main constraint | Why try it? |
|---|---|---|
| Whiskerdoku | One cat per row, column and region; no touching | Browser practice with undo and explanatory hints |
| LinkedIn Queens | One crown per row, column and region; no touching | A daily board with closely related visual logic |
| Star Battle | A fixed number of stars per row, column and region; no touching | Explore one-star, then more demanding multi-star variants |
| Classic Sudoku | Digits cannot repeat in rows, columns or boxes | More candidate bookkeeping and number-based patterns |
| Minesweeper | Numbers count nearby mines | Local counting and risk-aware exploration |
LinkedIn Queens: the closest visual relative
LinkedIn’s rules specify one queen in each row, column and colored region, with no adjacent crowns, including diagonals. That makes the core placement logic closely related to Meowdoku. If you already use X marks and region locks, those skills carry over.
The presentation is different: crowns replace cats, and LinkedIn organises the game around a daily puzzle. Its official help page describes hints, undo, automatic X placement and rule checking. Follow the help page’s game link for the current board.
Star Battle: take the same ideas further
Start with the one-star variant: each row, column and region needs one star, and stars cannot touch. You can reuse line locks and candidate counting. Multi-star puzzles increase the required stars per unit and introduce stronger capacity deductions.
Krazydad offers printable examples in different sizes and star counts. Check the requirement on each puzzle rather than assuming every Star Battle board uses one star. A two-star board cannot be solved by a one-cat solver without changing its rules.
Classic Sudoku: similar discipline, different objects
Sudoku also rewards writing candidates and checking intersecting units, but a full grid contains digits in every cell. Its boxes are usually regular 3×3 units; Meowdoku’s regions are irregular shapes, and most squares stay empty.
Choose Sudoku if you enjoy comparing several candidate digits. Choose a cat-placement puzzle if you prefer reasoning about which single location a region must use. The two games share a patient elimination habit rather than identical rules.
Minesweeper: local evidence instead of global placement
Minesweeper uses numerical clues to constrain neighboring mines. Meowdoku uses the no-touching rule to constrain neighboring cats, but it does not have those numbered mine counts. The analogy helps explain deduction; it should not replace the actual rules.
Choose Minesweeper if you enjoy tightly local clue combinations. Return to Meowdoku or Queens when you want row, column and region constraints to interact across the whole board.
Build a practice ladder
- Solve a small one-cat board with complete row, column and region cleanup.
- Try a board that requires a region-to-line lock.
- Study one concrete Meowdoku walkthrough and explain its opening move.
- Move to a larger one-star board or a daily Queens puzzle.
- Try a multi-star puzzle only after reading its additional star-count requirement.
Whiskerdoku supplies independent browser boards for the first part of this ladder, with undo, saved progress and hints you can inspect.
