The goal of Codecrack is to be the first to find the random code. An element can appear multiple times in the code to be found.
Taking turns, the players lay down a series of elements after which they receive feedback regarding the code to be found. A positive colored line indicates that a laid element is in the correct position. A neutral colored line indicates that a laid element appears in the code to be found, but is not in the correct position. A negative colored line indicates that a laid element does not appear in the code to be found.
The game ends when the code is found or when 24 codes have been placed.
