If you have two sevens & a joker, for example, you can use the joker to finish a set of three sevens or, if it fits into a sequence, you can even use it in a run. Wild caruk slotsds, however, should only be used sparingly even though they can be very helpful. You risk missing out on opportunities if you hold onto wild cards for too long and don't meld them before another player goes out. You should also exercise caution when discarding wild cards because you might unintentionally help an opponent finish their melds.
