Guess today's hidden number between 1 and 10,000 in 6 tries.
Every day sets a digit sum — shown at the top. The hidden number's digits add up to it, and so must every guess you make.
After each guess, the bar on the left of the row tells you how close you are:
The 4 dots on the right of the row count how many of your guess's digits appear in the target (any position). All 4 dots filled means every digit is in there — somewhere.
The system narrows down possible answers using your overlap counts. For digits you've typed:
IN — provably in the target (every remaining candidate contains it).
PLAUSIBLE — still in play; can't yet prove either way.
OUT — provably not in the target.
Untyped digits stay neutral.
Same number for everyone, refreshing at midnight local time.
