A new killer sudoku every day
Every day there is one new killer sudoku here, the same for everyone who plays it. A new puzzle arrives at midnight UTC: early evening in the Americas, and overnight in Europe. Like every puzzle on this site, it has exactly one answer and can be solved by reasoning alone, without guessing. Nothing to sign up for or install, and the puzzle you start is saved in this browser until the day is over.
The level follows the week, so you can ease in and build up:
- Monday and Tuesday: Easy, with small cages and some single squares.
- Wednesday, Thursday and Friday: Medium, with larger cages and the 45 rule on a row, column or box.
- Saturday and Sunday: Hard, with the largest cages and the 45 rule across several rows or columns.
Your time, your streak and sharing
The clock starts with your first number or note and runs only while the puzzle is on your screen, so a phone call or a cup of tea never counts against you. Solve the daily on days in a row to build a streak; miss a day and it starts again at one. Your streak is kept in this browser.
When you finish, Share copies a short result to paste into a message or a post. It shows the day, the level, your time and whether you used Hint or Check, and never a single digit of the grid, so you can send it before your friends have played:
How to play
Fill the grid so that every row, column and 3 by 3 box holds the digits 1 to 9 once each. The dotted outlines are cages: the digits in a cage add up to the small number in its corner, and no digit repeats within a cage. Tap a square, then a number; turn on Notes to jot down possibilities.
