	//	Go clockwise through each player.
	//	Player rolls 2 dice. Must pick unflipped numbers that add up to the
	//	rolled number. If this cannot be done, the player is done, and then
	//	adds up the numbers left unflipped. 
	//	The gameplay continues clockwise until someone flips up all their
	//	numbers, or all the players have been reached. The player with the
	//	lowest total wins. If someone manages to flip all their numbers, they
	//	win if the next player cannot. If the next player also flips all their
	//	numbers, then nobody wins, and continues in a circle until it reaches
	//	the player that first flipped all their numbers up. When continuing a
	//	game, the person who won the last round goes first, then it continues
	//	clockwise.
