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
- Open the board. No sign-up, no download.
- 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.
- Clear the board. Use a hint if you get stuck — the daily board is always solvable.
