Word ladder for everyone

Word ladder is a game that allows you to transform a start word to an end word, one word at a time. You can only change one letter in each transformation.
A valid transformation for FOOL to SAGE is FOOL -> POOL -> POLE -> PALE -> SALE -> SAGE

This app offers transformations from 4-letter to 10-letter words. It also includes a category that allows you to learn words by providing an automated transformation between a start word and an end word.

Swear words have been filtered out and are not allowed as part of the solution.
