Welcome aboard the Train of Thought! Travel across the USA aboard its expansive railroad network. Each station presents you with a puzzle, consisting of a set of words that has been chopped up and needs to be put back together based on clues. Practice your vocabulary, from common words with cryptic clues all the way up to those top-shelf ones we rarely use. Train of thought is also a fun way to prepare for the SAT!
Ten different routes are currently available, and many more to be added soon!
