Play Sudoku at Work: A Spreadsheet in Disguise

Sudoku is the ideal desk game: turn-based, pausable, endlessly replayable, and — crucially — it's already a grid of numbers. Which makes it the easiest game in the world to disguise as a spreadsheet.

It looks like a finance file

Spreadsheet Sudoku renders the board with column letters, row numbers, a formula bar and sheet tabs. Given numbers sit in cells like real data. A passer-by sees reconciliation work.

It plays like real Sudoku

Full pencil-mark notes, error checking, multiple difficulties, and a clean on-screen number pad on mobile so you can play one-handed on your phone too.

And it hides instantly

Tap Esc three times and the puzzle becomes a blank Book1 sheet. No tell. Play Spreadsheet Sudoku free — free in your browser.
