What I personally liked a lot the different Joker, which are no longer used anywhere now and the new action cards that also offer new strategic possibilities.
Who does not know, you're about to interpret its phase and suddenly makes a different team-mate. In the previous then you could start with new cards from the beginning again. In Phase 10 MASTER might be lucky and "keep everything" an action card have on hand and may in this case, inasmuch as you have played the card on time, keep the cards for the next round on the hand.
The jokers I find it very good that they are no longer used anywhere, but they are divided into color and numeric ranges. So you have for example a wild symbol which can be used only for red and green and only in the range of numbers 1-6. This may also happen that you get a Joker on hand, the one does not help to end the stage.
The as brief overview of a game that I really like.
CONCLUSION: I would recommend the Phase 10 MASTER, just as it did the predecessor, absolutely recommend.
Have Fun!
