Train of Thought, designed by Jay Cormier and Sen-Foong Lim and published by Tasty Minstrel Games, is a “guess as many words as you can in two minutes” party game like many others.

The twist is that you must give three word clues, and each clue must include the previous guess (or one of the previous guesses, if more than one player is guessing) as one of the words.

Unlike many other party games, there is no superfluous board in the box.
