DAILY NUMBER
Daily number, how many guesses?
One four-digit puzzle per day, the same for everyone (no repeated digits). Enter four distinct digits to get A/B feedback: A means correct digit in the correct spot, B means correct digit in the wrong spot. Reach 4A0B as fast as you can. Progress is saved locally and shareable.

How to play / tips
Start with a guess of distinct digits (e.g. 0123) and narrow down using A/B feedback — more A means more correct positions. Use elimination to fix each digit and place. A new same-for-everyone puzzle appears at midnight; the number is the day index, so compare with friends.
FAQ
Is the answer the same daily?
Everyone gets the same answer on a given day (generated deterministically from the date), so you can compete; it refreshes at midnight.
Is progress lost / uploaded?
Progress is in browser localStorage — survives refresh, not synced across devices; nothing is uploaded.
