【實用解謎app】Cows and Bulls|最夯免費app

Cows and Bulls or Bulls and Cows is an old code-braking mind game similar to the board game Mastermind.

The game is played using a four digit number.

Your goal is to guess a random secret number that doesn't contain any duplicates.

For each guess you can receive a hint like 'bull' or 'cow'.

Example:

Secret number: 4271

Your guess: 1234

Answer: 1 bull and 2 cows. (The bull is "2", the cows are "4" and "1".)

Try to guess the secret number using as little as possible turns.

Good Luck!
