To complete a phase, a player must lay down the required sets or runs in front of them and then discard one card onto the discard pile. The specific requirements for each phase are listed on the Phase 10 instruction cards. For example, Phase 1 may require two sets of three cards, while Phase 2 may require one set of three cards and one run of four cards. In each phase, players must collect sets or runs of cards that fit specific criteria. The objective of Phase 10 is to be the first player to complete all ten phases and declare oneself the winner. Phase 10 is a card game that is played with a standard deck of cards and combines elements of rummy and strategy.
