You need 7 melds to win. With your initial hand, identify which cards can be melded and which can be thrown away. Keep track of the cards that you need for melding.
Pay attention
It is always good to have multiple of one card, but you should keep track of the cards in the ground melds, field melds, and the discarded. There are a four of each card, so if there are more of that card in the discarded pile or in the melds, the less likely you are to find one in the deck. because of this your strategy may need to change over time, especially when claiming a general that is drawn from the deck.
