Learning Algorithms Through Play

In The Computer Always Wins: A Playful Introduction to Algorithms through Puzzles and Strategy Games (MIT Press, 2025), Elliot Lichtman will teach you some of computer science’s most powerful concepts in a refreshingly accessible way: exploring them through word games, board games, and strategy games you already know. Learn recursion by playing tic-tac-toe, efficient search through puzzle games like sudoku and Wordle, and machine learning by way of the playground classic rock-paper-scissors. Finish the book, and you’ll come away with not only a deeper understanding of these foundational programming techniques but also a new appreciation for the amazing feats that can be accomplished using simple, readable code.

Elliot Lichtman started teaching online classes in computer science when he was a freshman in high school. Small classes quickly grew into a series of larger and longer offerings, and from those, this book was born. Elliot is currently a junior at Yale University.
