Word Trek: An Adventure from Start to Finish! Inspired by Lewis Carroll By the creators of Tangoes Contains two decks of cards in a plastic case (VHS-like, but smaller). Provides 216 word puzzles and solutions. Can be played solo as a puzzle, or with groups (parties, travel -- "Word Trek makes a family trip fun!"). From the publisher's website: A Word Trek Puzzle is a pair of words with the same number of letters (For Example: dog / cat). The objective is to transform one word into another word, through step-by-step transformations. Using paper and pencil, players either change or rearrange (anagramming) one letter from the first word to make another valid word. (For Example: dog, dot, cot, cat.) WORD TREK develops logical thinking while building vocabulary and improving spelling skills.
