What changed in the game, in plain language. This list follows the project’s dated update history and includes only changes that players can see, hear, or use.
Level guide pages retired
The 250 original-mobile level pages and their index are gone. Each was a level number, a coordinate list and an embedded third-party video, and none of them said anything the video did not.
The level data itself is unchanged and still verified against all four Meowdoku rules — it is raw material for writing about the puzzle, not a reason to publish a page per level.
A bigger board while you play
The puzzle board is larger on every screen. Small phones and short windows gain the most — up to about half again as wide — and a full desktop window gains about a fifth.
The level and difficulty label moved up into the top bar, so it no longer takes a row of space away from the board.
A mistake message now appears over the board when it happens, instead of an empty line being held open for it the whole game.
Each rule above the board now sits beside its small diagram rather than under it, which shortens the strip without dropping any of the three rules.
On narrow phones, the Undo, Hint, Auto, and Reset buttons no longer run off the side of the screen.
A new Extreme difficulty
Extreme joins Easy, Normal, and Hard: a 10×10 board that hands you only one free single-cell region instead of two, so there is one less answer written on the board when you start.
Extreme boards are built in the background, so choosing the new difficulty shows a short “generating” message instead of freezing the screen.
Daily Challenge times no longer count towards a difficulty best time. The daily keeps its own “done today” mark, and its 10×10 result is no longer compared against your 9×9 Hard record.
More campaign levels and a bigger daily puzzle
The browser campaign now runs through Level 150, with larger boards introduced as you progress.
The Daily Challenge is now a 10×10 puzzle for a longer once-a-day solve.
The rules strip takes up less room during desktop play, leaving more space for the board.
More board space on shorter screens
On phones, tablets, and short laptop windows, the game now compacts the rules and controls so the puzzle board stays larger and easier to tap.
Smoother movement between screens
Opening a new puzzle preview no longer unexpectedly sends you back to the home screen.
Each screen now opens at the top, instead of keeping the scroll position from the page you just left.
Original mobile walkthroughs through Level 250
Level Guides now cover original mobile Levels 1–250 with solved boards and walkthrough help.
Clearer solver flow and gentler sounds
The screenshot solver now begins with a clean board and waits until it has read your screenshot before the Solve button becomes available.
Cat-placement sounds were softened and balanced so repeated moves are less distracting.
Screenshot solver launched
You can upload a Meowdoku screenshot, let the browser detect its colored regions, and reveal a valid solution without sending the image away from your device.
The home board now gives a clearer “tap to play” prompt for first-time players.
A deeper campaign and better mobile play
The campaign expanded to 100 levels, ending with a 10×10 puzzle, while new boards generate without freezing the game screen.
Daily Challenge hints were removed so everyone tackles the same puzzle without reveals.
Scrolling across the board on a phone no longer counts as an accidental move.
Cat artwork and background audio were made lighter to speed up loading on mobile connections.
In-game navigation was simplified, and a help button now keeps the rules close without crowding the board.
The results card now shows score, combo, time, mistakes, and hints used.
Practice boards gained proper input controls and a solution reveal, and the Tips page gained a playable example.
Campaign mode, live home board, and responsive layout
A 20-level campaign joined the random Easy, Normal, and Hard puzzles, then expanded to 50 levels later the same day.
The home screen gained a live playable board and an animated rules walkthrough.
The layout was rebuilt to fit both desktop and mobile screens more reliably.
How to Play and Tips became full pages, and the interface gained English, Spanish, French, German, Portuguese, and Italian options.
First playable release
The first browser version launched with generated cat-logic puzzles, hints, undo, three fish-cracker lives, a timer, sound controls, and light and dark themes.
Invalid cat placements are now removed immediately, and hints ignore the ✕ marks you add yourself.
Puzzle generation became dramatically faster, especially for 9×9 boards.
Boards gained clearer colored regions, always-visible rule reminders, and fish crackers that show remaining lives.
An optional Auto-cross mode can mark cells ruled out by a placed cat.
Background ambience and a quiet marking sound were added, followed by the soft lavender visual style used today.
