Play solo, take the Daily Challenge, or duel the computer and your friends.
- Classic code-breaking with a modern neon design and color-plus-symbol pegs.
- Solo, Practice, Daily Challenge, and duels vs AI, pass-and-play, or online.
- Global, regional, and group leaderboards to track your progress.
How it works
Read the pins. Refine the guess. Break the code.
A secret code of 4 colored pegs is hidden from you. After every guess you get feedback pins: a black pin for each color in the right position and a white pin for each correct color in the wrong position. Use that logic to narrow the possibilities until you crack the code. Read the full rules.
Pure deduction
No luck, no timers to fight: every guess gives you information, and every solve is earned by logic.
Head-to-head duels
Set a secret code for your opponent and race to crack theirs first, against the AI or a real player.
A new puzzle every day
The Daily Challenge gives every player the same code. One attempt per day, eight guesses, one leaderboard.
