It's definitely Uno. The PC version tends to be hit and miss on if it'll work fine or just crash. I do like all the mechanics this one has (granted they might just be things Uno has always had and I just didn't know) like 7s and 0s making people change hands, stacking, challenging, etc. These can be turned off if you like which is a good thing cause they tend to make games go on for longer than needed.
