Notice that "Uno" is the name of an american (not italian) card game, which is quite popular, just google it. However Uno refers to one game by the producer rather than the producer itself so I don't think Uno+Toys makes much sense for them to acquire this domain. Still, if you develop it into a toys and games site it might have quite some value imo, also banking on the popularity of the Uno card game and relative SE weight.
