How to play
How it works
Three steps to your first cracked code.
1
Step 1 · SetupChoose your difficulty.
Pick 4, 5, 6, or 7 digits. Fewer digits is fast and forgiving. More digits is slow and brutal.
2
Step 2 · PlayGuess and reason.
Each turn, submit a guess. You see how many digits are correct and how many are in the right place. Use the feedback to narrow down the possibilities.

Step 3 · RepeatWin, lose, or repeat.
