Because of the good reviews I let myself be tempted to buy Phase 10 Master. We have the normal phase 10 understood in a very short time and were very impressed. I thought to myself, as I take the same Master version - is certainly more exciting. Unfortunately, I'm wrong about the adoption. First, it is much more complicated by the new action cards and on the other hand much longer and that in turn means that the fun factor suffers enormously. Personally, I can therefore recommend the normal phase 10 (playing time approximately 1 hour.) Much, the Master Edition (game time about 4 hrs.) But unfortunately not.
