Codebreaker — Grid #59 · 31 October 2026

Codebreaker is a deduction game built around a hidden code. You uncover it by making guesses and interpreting the feedback after each attempt. Depending on the difficulty, the code contains between 3 and 7 digits.

Find the hidden code in as few guesses as possible. If two players finish in the same number of attempts, time is used only as the tiebreaker.
