Can I still play the Daily Sudoku puzzle from September 15, 2026?

Yes. Every puzzle stays playable in the archive, so you can open puzzle #43 and solve it yourself at any time.

Does every puzzle have exactly one solution?

Yes. After each digit is removed during generation, a counting solver re-checks the grid and stops as soon as it finds a second solution. Any removal that would create ambiguity is undone, so every published grid is provably unique.

How hard is today's sudoku?

It depends on the day. Monday, Tuesday and Wednesday are easy, Thursday and Friday are medium, and Saturday and Sunday are hard. The number of blank squares rises with the difficulty, from about 40 on easy days to the mid-fifties at the weekend.

Do I need to guess or use trial and error?

No. Uniqueness means the solution can always be reached by elimination. Harder grids may need techniques beyond naked and hidden singles — pairs, pointing candidates, box-line reduction — but never a guess.
