Tips

  • Pick one number and look across the board for places where only one cell can take it.
  • When a cell has only one candidate left, that number is the answer. Noting candidates in note mode makes them easy to spot.
  • If, inside one box, a number can only go in a single row or column, you can rule it out of that line in the other boxes.

Frequently asked questions

Do I lose my progress if I reload?

Your progress is kept in this browser for a while, so you can carry on after reloading or reopening the window. The clock keeps running meanwhile.

How does a record get on the leaderboard?

When you finish, the server checks your solution again and then you can post the record. Within each difficulty, shorter times rank higher.

What happens when I use a hint?

The selected cell is filled with the answer and 60 seconds are added to your record each time. You can use up to 3 per game.
