About Daily Bulls & Cows
Crack a new 4-digit code every day using classic Bulls & Cows logic. You get eight attempts, and each guess returns bulls (correct digit in the correct position) and cows (correct digit in the wrong position). Use deduction and pattern elimination to maximize your daily score before leaderboard launch.
How to Play
- Enter a 4-digit guess and submit.
- A bull means a correct digit in the correct position.
- A cow means a correct digit in the wrong position.
- All digits in the code are unique.
- Use each result to narrow the next guess.
Rules
- -One seeded code per day — same puzzle for everyone.
- -You have a maximum of 8 attempts.
- -Guesses must be exactly 4 digits (0-9).
- -Repeated digits are not allowed in a guess.
- -Sign-in required. Your daily results are tracked on the global leaderboard.
Tips
- -Start with four different digits to maximize information.
- -If a guess has 0 bulls and 0 cows, eliminate all four digits immediately.
- -When bulls increase, keep those positions stable and rotate the others.
- -Use cows to test permutations before introducing fresh digits.
