Whoever has the most diamonds at the end of the game wins. The deck in Diamonds consists of sixty cards, numbered 1-15 in the standard suits. In each round, each player starts with a hand of ten cards. One player plays a card to lead to the first trick, and everyone else must play one card, following suit if possible.
