Code Hack: Crack the Code

A hidden colour code. A handful of guesses. Nothing but logic to get you there. Code Hack is a classic code-breaking puzzle. Each guess comes back with two clues: a black peg for the right colour in the right spot, a white peg for the right colour in the wrong spot. Read the clues, narrow the field, crack the code. CHOOSE YOUR CHALLENGE Three difficulty levels change the code length, the colour palette and how many guesses you get. Easy is a warm-up. Hard will make you keep notes. DAILY CHALLENGE One code a day, the same for everyone, generated from the date. Build a streak, track your best run, and share your result as an emoji grid without spoiling the answer for anyone else. TWO PLAYERS, ONE PHONE Pass-and-play: one of you sets a code, the other breaks it, then you swap. Fewer guesses wins. No second device, no account, no internet. TRACK EVERYTHING Win rate, current and best streak, average guesses, and a breakdown of how many tries your wins actually took. Eleven achievements with progress bars, from your first crack to a hundred games played.
