How to Play Bulls and Cows
Bulls and Cows is a classic code-breaking deduction game where one player thinks of a secret number and the other tries to guess it using logical clues.
The Basic Rules
- Bull — A digit is correct and in the correct position.
- Cow — A digit is correct but in the wrong position.
- The goal is to deduce the secret 4-digit number in as few guesses as possible.
Example Round
Secret: 8361. Guess 1234 gets 0 bulls, 2 cows. Guess 3456 gets 1 bull, 1 cow. Guess 8361 gets 4 bulls — solved!
Tips
- Use a consistent first guess like 1234 to test which digits appear.
- Track confirmed digits and their possible positions.
