How Word Ladder Works
  • Enter a start word and an end word of the same length.
  • The solver finds the shortest path by changing one letter at a time.
  • Each intermediate word must be a valid dictionary word.
  • Example: CAT → COT → DOT → DOG (3 steps)
  • Click any word in the path to view its definition.
