Four digits.
Ten guesses.
No luck involved.
Every code can be cracked by logic alone: read the feedback, eliminate the impossible, close in. The display runs the app's own evaluator, so the round below is the real thing.

10,000 codes are possible. Deduction is how you cut them down.
HOW THE READOUT WORKS
Feedback is the whole game
Two of the classic modes report the same truth in different languages. One paints it. One counts it.
COLOR MATCH
Green sits in the right slot. Gold is the right digit in the wrong slot. Grey is not in the code.
- right slot
- wrong slot
- not in code
PRECISION
No colours. Two numbers: how many digits are exactly right, and how many are right but misplaced. Digits never repeat, so 5,040 codes are in play.
Two digits nailed. One digit present, wrong slot. One not in the code at all.
SEVEN MODES · ONE MECHANIC
The same deduction, made harder seven ways
Each mode changes what the code tells you, or what it costs to be wrong. Matches are staked in tokens — win and you take the pot.
