TIPS FOR SUCCESS

1. Start with hints that have the most constraints (like "prime" or "palindrome")
2. Use candidate mode to track possibilities
3. Look for intersections where words cross - they must share the same digit
4. Cross out completed hints to focus on remaining challenges
5. Remember: no zeros! Every number must be 1-9
