The next level of Phase 10™ is the Masters Edition, now available in a collectible tin. This advanced game play was developed by Kenneth Johnson, the inventor of Phase 10™. You are given a set of ten Phase cards. After a hand is dealt, you select the phase you think you can complete, adding a new level of strategy to classic Phase 10™ play. A unique feature allows you to set aside one card per hand for use in future phases. Tin contains 146 cards and instructions.
