Daily Schulte Challenge
Every day brings one fresh grid — the same board for every player on the planet. Finish it, then send your challenge link: friends play the identical board and try to beat your time.

How the daily challenge works
The daily grid is generated from the UTC date as a random seed, so everyone everywhere plays the exact same board each day. Your result, personal best and day streak are stored locally in your browser — no account, no leaderboard server.
Challenge a friend
After finishing, hit “Challenge a friend” to copy a link containing your board seed and your time. Whoever opens it plays the identical grid with your time as the target — zero backend, pure URL magic. Bragging rights included.
