Tier 15 reward is not givien to you, even tho it tells you, you've won. its not given to you for some reason. Also in this game it might not give you the payouts as written. It has happened alot to me and my friends.
I tried the Liars dice a couple of times but found it lacking. I don't really remember what the issue was anymore, but I think the game didn't follow the traditional rules that I always played by, and I found the minor rule difference too much of an annoyance. As I recall the issue for me was around the bidding, that the step up in bidding process didn't work right.
