I want to first say that Phase 10 is amazing. I play almost every day. I have also enjoyed the game variations. They are fun to play, and give some change of scenarios. I have noticed that some of these games are highly predictable. When you get a large lead then you will consistently lose back to back games until the AI player catches up. If it were random, I would be good, but I can almost predict what's going to happen and it does. Just creating a more random game, much like the original would make those new games more exciting. I would also like to concur with some others that suggest coins for wins. One last thought, would it be possible to track wins and other factors so that I can see my history in regards to specific phases of the game. This would be a great feature for sure.
Thanks again for giving us a place to make suggestions.
