Tips & Best Practices

💡

Start with a diverse set of numbers (e.g., 1234) to eliminate digits quickly.

💡

If you get 0 Bulls and 0 Cows, you've eliminated multiple digits at once!

💡

Keep track of which digits have been confirmed as "not in the sequence".

💡

Short codes (3 digits) are great for beginners, while long ones (9 digits) are for masters.

💡

In "Create" mode, choose a number with repeating digits for an extra hard challenge.

Answers

Frequently Asked Questions

Q What is the Bulls and Cows game?

Bulls and Cows is a classic code-breaking game where players guess a secret combination of digits. For every guess, the game returns clues: "Bulls" represent correct digits in the exact correct position, and "Cows" represent correct digits in the wrong position.

Q How does the game count Bulls and Cows?

A "Bull" is recorded when one of your guessed digits matches the secret number's digit in the exact same index. A "Cow" is recorded when a digit in your guess is present in the secret number, but is positioned at a different index.

Q Are duplicate digits allowed in the secret number?

It depends on your game settings! By default, the secret number contains distinct digits. However, you can toggle the "Allow Duplicates" option in the game settings to allow duplicate digits for an extra layer of difficulty.

Q How do custom challenge links work?

When you create a custom game, the secret number, maximum attempts, and optional hints are encrypted using an XOR cipher client-side and appended to the URL. The recipient can play the game immediately without any data being stored on a server, ensuring 100% privacy.
