How to Solve Word Ladders

A repeatable 5-step method

1. Compare start vs target: mark fixed letters and mismatch positions.
2. Choose one position to improve: avoid changing two ideas at once.
3. Prefer common bridge words: use frequent patterns like -AR-, -OR-, -IN-.
4. Keep backup branches: when stuck, roll back one move instead of restarting.
5. Check legality each turn: one-letter change, same length, valid dictionary entry.

Worked walkthrough: COLD → WARM

One efficient route is COLD → CORD → CARD → WARD → WARM. Notice how each move nudges one position closer to the target while keeping a high-frequency word shape. This is the core ladder habit: controlled, low-risk transitions.

Common failure points

• Changing a letter that already matches the target.
• Jumping into obscure words that block next moves.
• Forgetting to track visited words and looping.
