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.
