Please be as specific as possible when letting us know what is missing or incorrect. For example, say "this game's trophy difficulty should be 8/10", with a link to a website corroborating this difficulty estimate (if possible), not "this game's trophy difficulty is wrong".
Uno - Trial does not have any trophies. This is because it is a demo and/or soundtrack, neither of which typically get trophy lists. The full (i.e., paid) version of the game likely has a trophy list.
UNO makes its return with new exciting features such as added video chat support and an all new theme system which adds more fun! Match cards either by color or value and play action cards to change things up. Race against others to empty your hand before everyone else in either Classic play or customize your experience with a variety of House Rules.
