The code for the function game is defined with the argument order [word, player]:
(defn game
[word player]
...)
This [word player] argument order is used everywhere a function definition for game appears (pages 250, 251, and 257).
Whenever sample REPL code for calling the game function is shown (pages 254-258), the argument order is swapped to [player word]. e.g.:
(game random-player "hello")
