‘Doublets’ is the name of the popular word puzzle invented by Lewis Carroll (the author of Alice In Wonderland) – now also known by a variety of other names: Word Ladders, Ladderwords, Stepwords, Word Chains, Laddergrams, Transitions, Transformations, etc.
Transform one word into another by changing a single letter in each step, so that each link in the chain is a valid word. For example, to change MORE into LESS with 3 links:
M O R E (Original Word)
L O R E (Link 1)
L O S E (Link 2)
L O S S (Link 3)
L E S S (Transformed Word)
Its pretty easy and it’s a good way to check your active vocabulary and develop your puzzle solving skills.
