Play Bulls and Cows (number baseball) online for free. 3, 4 and 5-digit modes, limited-guess challenge, strike/ball feedback, fewest-guesses records. No install needed.
Crack the secret number with strike and ball clues.
Bulls and Cows — known as number baseball in Korea — is a classic code-breaking game. A right digit in the right place is a strike (bull); a right digit in the wrong place is a ball (cow).
Three modes await: easy 3-digit, classic 4-digit, and hardcore 5-digit — plus an optional challenge mode where you must crack the code within a limited number of guesses. If none of your digits match, it's an OUT — and even outs are valuable clues.
Your fewest-guesses record is saved for each mode. Combine the clues from every guess, narrow down the candidates logically, and crack the code in record time.
A strike (S) means the digit and its position are both correct; a ball (B) means the digit is right but in the wrong spot. If none of your digits are in the code, you get an OUT.
No — the secret number is made of distinct digits, so your guesses must have no repeats either. You can pick from 3-, 4-, or 5-digit modes.
Challenge mode limits how many guesses you get: 8 for 3 digits, 10 for 4 digits, and 12 for 5 digits. If you don't crack the code in time, you fail the round.
