Winning Strategies

1

Start with Different Numbers

Your first few guesses should use completely different numbers to identify which digits are in the secret code.

2

Track Your Clues

Keep mental notes of which numbers have appeared as killed or injured. Use previous results to inform your next guess.

3

Test Positions Systematically

Once you know which numbers are in the code, test different position combinations methodically.

4

Use Process of Elimination

When you get 0 killed and 0 injured, you've eliminated 4 numbers! Focus on the remaining 5 digits.
