Not sure if it’s “proper”, but you could just alts! twice on all three
channels:
(let [[_ p1] (alts! [player1-ch player2-ch timeout-ch])
[_ p2] (alts! [player1-ch player2-ch timeout-ch])]
(cond
(= p1 timeout-ch) "No players played."
(= p2 timeout-ch) (str p1 " played, and the other player did not play.")
:else "Both players played before timeout."))
