To use, a player discards the Skip card on their turn and chooses the player who will lose a turn. Skip cards have only one purpose: to cause another player to lose a turn.

A Wild card may not be used as a Skip card.If the dealer starts the discard pile with a Wild card, the card may be picked up by the first player.It must remain as that card until the hand is over. Once a Wild card has been played in a Phase, it cannot be replaced by the intended card and used elsewhere.Players can use as many Wild cards as they want as long as they use one natural card. More than one Wild card may be used in completing a Phase.Original print runs of Phase 10 had two Wilds in each color to reduce confusion, current print runs use black Wilds.

A Wild card may be used in place of a number card and can be used as any color to complete any phase.
