+* TODO Basic Game mechanics :game:
+Now that we have singles, pairs, and triples, let's implement a basic
+2-player version of the game.
+
+We'll ignore player election for now in favour of random ordering.
+
+Here's the basic order of play:
+1) Round chooser player plays a hand of whatever round type they want
+2) Each player takes turns playing a hand of that round type better
+   than the previous hand
+3) If either player skips, they pick up a card, and the other player
+   becomes the round chooser (allowing them to choose a new round
+   type)
+4) If player (A) uses up all their cards, and the other player does
+   not footstool them, that player (A) wins.
+
+We must also implement footstooling:
+- If player (A) plays a hand, and the next player plays a hand that
+  half footstools it, then player (A) must pick up a card.
+- If player (A) plays a hand, and the next player plays a hand that
+  full footstools it, then player (A) must pick up 2 cards.
