Warning! This game takes a very, very, very long time. Phase 10 +10 is played with a deck of Phase 10 cards and played the same way as the proprietary game Phase 10 except that the 10th phase only marks the half way point! After the 10th phase there are 10 more and here they are: Phase 10 is a commercial version of the traditional card game Contract Rummy, but while Contract Rummy is played with standard playing-cards, Phase 10 uses special cards and has a somewhat different sequence of contracts. It is a collection of variations of the proprietary card game, Phase 10. This page is part of the Invented Games section of the Card Games web site.
