I verify every board is solvable before it ships. That is the claim the name is staking.

What it does

  • A new board every day — the same one for everyone, so a hard day is hard for everybody.
  • Plays in a browser — nothing to install, works on your phone or your desktop.
  • Hints, undo and shuffle — there if you want them, I never force them on you.
  • Also on iPhone and Android — the same game, offline, even on a plane.

How to use it

  1. Open the board. No sign-up, no download.
  2. Match free tiles in pairs. A tile is free when it has an open edge on the left or right, and nothing sitting on top.
  3. Clear the board. Use a hint if you get stuck — the daily board is always solvable.

Questions

Do I need an account?

No. Nothing to sign up for, and I do not store anything about you.

Is the daily board the same for everyone?

Yes. Everyone gets the exact same layout, every day.

Is there a version I can play offline?

Yes, on both iPhone and Android.
