A secret number
you ought to find,
You are bound by nothing
but space and time.
How many miss and match
each move will tell,
If you lose track
keep calm and don't yell.
Play for glory
or just to unwind,
Either way let's see
how far you can stretch your mind.
Same rules, more ways to have fun.
Share a link, solve the same number, and see who cracks it first.

One secret number, the same for everyone in the world today. One go each – how few guesses can you crack it in?
Cows and Bulls, also known as Bulls and Cows, is a classic code-breaking number puzzle. Guess the secret number, and every try tells you how many digits are right and in the right spot (Bulls) and how many are right but in the wrong spot (Cows). If you enjoy Wordle-style puzzles or Mastermind, you’ll feel right at home – with numbers instead of letters.
