About this game

CodeBreaker is a terminal-style logic game about cracking hidden number codes.
Guess the secret sequence using only two clues:
HIT: the digit and position are both correct
BLOW: the digit is correct, but in the wrong position
That is all you get. Read the clues, narrow the possibilities, and break the code in as few turns as possible.
Play Your Way
SOLO PLAY
A fully offline single-player mode. Customize the base, number of digits, duplicate digits, and hint display to create anything from quick practice rounds to brutal logic puzzles. No sign-in required.
VS CPU
Race against the CPU in local battles. Choose EASY, NORMAL, or HARD, then try to crack the code before your opponent does. A great way to sharpen your instincts before entering rating matches.
RATING
Compete in asynchronous online matches against players near your rating. Matches can run up to 24 hours, so you can play one move at a time without keeping your opponent waiting.
Rating matches use fixed fair-play rules: base 10, 4 digits, no duplicates, no hints, and no assists. Win by cracking the code in fewer turns. Your Elo-style rating changes based on the result.
Choose a TEMPO, submit your secret code, and enter the queue. Sign-in is required for online play.
