## What is XXI?

XXI is a one-minute daily number puzzle.

Every day there's one 4×4 grid of digits — the same grid for everyone, everywhere. Drag a path through neighbouring tiles so they add up to exactly 21. Go over and you bust. Hit 21 and you can lock it in — or keep looking for a longer path.

That's the whole game. The trick is that a quick 3-tile answer is always there, but the best path uses 7, 8, sometimes 9 tiles. Finding the long way is the point.

- One puzzle a day, no endless mode, no grind
- Score = tiles used. Longer is better
- See how your path compares with everyone else's today
- Streaks and stats that live on your device
- Spoiler-free share card for Stories and chats
- Optional daily reminder so you don't break the streak
- No account, no sign-up, no tracking
