Programming Clojure, 3rd Edition

Developing the Game Loop

There are many paths to developing successful applications with Clojure (or any language) and many ways this application could be written. However, writing any program involves starting from high-level goals and breaking the problem down into smaller problems, until it’s easy to solve each subproblem with a single (usually small) function.

Our application is a game with a single player where the player guesses letters to slowly reveal a word. The goal for the player is to guess all of the letters in the word with as few guesses as possible.
