The daily color-code puzzle

Hueristic is a free daily code-breaking logic puzzle. Each day there is one secret code made of colored pegs, and your job is to crack it in eight guesses or fewer. After every guess you are told how close you were — but never which pegs were right — so each row is a clue you reason from to corner the answer.

How to play in one minute

Tap colors to fill a row, then submit your guess. You get back two counts: how many pegs are the right color in the right place, and how many are the right color in the wrong place. Use those counts to rule colors and positions in or out until the code is the only thing left.
