Crumb

Crumb is a daily term-guessing game. Guess a real, domain-specific technical term in 6 tries, not a common English word, so solving it actually takes subject knowledge. Every guess gets colored letter feedback: green for the right letter in the right spot, yellow for the right letter in the wrong spot, gray for a letter that isn't in the word. Each domain below gets its own puzzle, once a day, with a clue shown throughout so the challenge is knowing the term, not guessing blind.
