Sudoku — daily
One deal a day, identical for every player in the world. Finish any daily to keep your streak.
Every row, column and three-by-three box holds each digit from 1 to 9 exactly once. Tap a cell, then a number. Notes writes small pencil marks instead — useful for holding the possibilities in a cell while you work out which is right. Clashing digits are marked in red, but a grid with no clashes can still be wrong. Every puzzle here can be solved by reasoning alone, so you never have to guess. Undo is unlimited within the last 80 actions.
How the daily works
Every player gets the same Sudoku deal on the same calendar day, wherever they are. The puzzle is generated from the date itself, so your result is directly comparable with anyone else's on that deal.
Your game saves as you go. Close the tab mid-deal and it will be waiting exactly where you left it.
