Nine Lives: Cat Sudoku Puzzle

New: Boss Boards. Every 25 levels the board hides its tiles and takes your hints away — three mistakes and it's over. Sudoku's logic, minesweeper's nerve.

One cat per colour. One per row. One per column. No two cats touching, not even at the corners. That is the entire rule set, and it is enough for a thousand hand-made boards.

Every board has exactly one solution and you can always reason your way to it. Mark the squares you have ruled out, follow what is forced, and enjoy the click when the last cat lands. Sudoku's constraints, minesweeper's deduction, none of the arithmetic.

-- THE DAILY CROWN PUZZLE, WITHOUT THE WAIT If you play the one-a-day grid where a crown goes in every row, column and colour and none may touch — this is that logic, unlimited. A thousand levels, a daily puzzle, endless mode, and cats instead of crowns.

-- WHAT YOU GET • 1,000 hand-crafted levels, from gentle 5×5 boards up to 12×12 • Twin Cats — a second rule set where every row, column and colour takes two, unlocked at level 150 • Boss Boards every 25 levels: cells hidden, hints gone, three mistakes and it is over • A fresh daily puzzle with streaks worth keeping • Endless mode that never runs out of boards • Cats to collect and themes to unlock as you play • Hints and reveals when a board defeats you • Fully offline — no wifi, no account, nothing to sign up for • Game Center leaderboards • One-time purchase removes ads forever. No subscription.

-- BRAIN TRAINING THAT IS ACTUALLY A GAME Small boards teach you the moves. 12×12 boards make you earn them. No timers unless you want one, no grind, no notification spam.

-- FOR THE QUIET MINUTES A board on the commute, one before bed, one while the kettle boils.

If you like sudoku, logic puzzles, brain teasers, brain training games, minesweeper, nonograms, or Queens and Star Battle grids, this is for you. And if you simply like cats, there are plenty here.

Free to play. Optional coin packs and a one-time ad removal.
