How the Daily Challenge Works
- A new puzzle every day — a fresh grid unlocks at midnight UTC, and the countdown above shows exactly when.
- Same puzzle for everyone — the daily grid is generated from the date itself, so every player solves the identical puzzle. Compare times with friends.
- Difficulty rotates through the week — the week ramps up, NYT-style (see the schedule below).
- Every puzzle is verified unique — the same generator quality as the rest of the site, guaranteed one solution.
- Missed a day? Recent puzzles stay playable in the archive below.
