FAQ
How do you play Bulls and Cows?
The code is made of different digits from 0 to 9. Enter a guess, and you'll be told how many digits are right and in the right place (bulls) and how many are in the code but in the wrong place (cows). Get all bulls to win.
Can I use the same digit twice?
No. The code never repeats a digit, so your guesses must use different digits too.
Any tips?
Spread out the digits in your first few guesses to find out which ones are in the code. Once you know the digits, swap their positions to turn cows into bulls.
How is the leaderboard ranked?
By the number of guesses, fewest first; ties go to the shorter time. You only need a nickname, and you can submit up to 30 times a day per length. The server checks your list of guesses.
