How to play

There's a secret 4-digit code with no repeated digits. After each guess you get clues:

🐂 a bull is a right digit in the right place.
🐄 a cow is a right digit in the wrong place.
💩 means a digit isn't in the code at all.

The clues don't tell you which digit is which. That's the puzzle.
