A word ladder puzzle has a source word and a target word, and to solve the puzzle you must find a chain of words to link the two, in which two successive words always differ by a single letter, which in math-speak means they have a Hamming distance of $$1$$.

Some variations of word ladders allow letters to be removed or added as well (Levenshtein distance), and/or transpositions (Damerau-Levenshtein distance).

Example:

| COLD | CORD| CARD| WARD V WARM 
forms a word ladder from COLD to WARM.
