You can either strengthen your hand or impede your opponents' progress with each turn. You must carefully evaluate how a card fits into your overall strategy before drawing it from the draw or discard pile. You risk losing turnsatta..kings and accruing more points in your hand if you pick up a card that doesn't add to your sets or sequences. Discarding is equally important; it involves more than just getting rid of cards that aren't needed; it also involves making strategic choices that have an impact on your opponents. You might want to hold onto a card until you can use it effectively, for instance, if it has the potential to assist an opponent in finishing their set or sequence.
