Another creation by Lewis Carroll is the game Doublets (also known as word ladder, word links, and word golf). You’ve probably played it before, but never even realized just who fashioned it! (I have!)
It’s a fairly simple game:
Two words of similar length are given. The objective is to transform the first word into the second word by forming successive words of the same length having changing only one letter at a time. The greater challenge is to do the transformation in the least number of words.
Yeah. That game. :D
