Home / Sudoku / Killer sudoku / Daily

One new killer sudoku every day, at medium level. It changes at midnight where you are, and everyone who plays on the same date gets the same puzzle.

How the daily puzzle works

Today's puzzle comes from our bank of 200 checked medium puzzles, taken in order, one a day, so you won't see the same grid again for 200 days. Each day it's also turned or mirrored, decided by the date. Every one has exactly one solution and can be solved without guessing, though each needs the rule of 45 at least once.

Solve it and your killer sudoku streak goes up by one. Skip a day and it starts again from one. This streak is separate from the regular daily sudoku streak, and it lives in this browser, so it follows you only on the same device.
