Padlock

A numeric take on code-breaking: the hidden combination has four digits and must be found within five attempts. After each guess, colours show which digits are in the correct position and which belong elsewhere, including repeated digits. Harder variants use five-digit codes or allow up to ten guesses, and a highlighting tool helps track candidates.
