Cat Sudoku at a glance
What is Cat Sudoku?
Cat Sudoku is a Queens-style placement puzzle. The daily board has seven rows, seven columns and seven colored regions. Place seven cats so that each row, column and region contains exactly one. Cats may not touch, even diagonally. There are no digits to enter.[1][2]
How to play Cat Sudoku
Tap a square to cycle between empty, cat and crossed out. On a keyboard, use the arrow keys to move around the board, then activate the focused square. Crosses are working notes. The Check and Hint controls help if you want to verify progress.[1][2]
A single placed cat rules out every other square in its row, column and region. Its diagonal neighbors are also unavailable. Check all four constraints when narrowing a candidate.[1][2]
Start with a region that has few options
Look for a compact region or a row with only a few open squares. If all of a region’s possible cats lie on the same row, that row’s cat must be in the region, so you can rule out other cells on that row. Save guesses for later if you still have a deduction to make.
When does the daily puzzle reset?
The daily grid uses your device’s local date and changes at midnight. A refresh on the same date keeps the same puzzle. The publisher saves the board, timer and streak in browser storage. Unlimited practice boards are separate from the daily challenge.[1][3]
The embedded daily board is the publisher’s original. If you switch browsers or open the publisher’s site in a separate tab, saved progress may depend on how the browser separates storage. Use the same browser and play location to continue.[1][3]
