UNO demo now on the Japanese Switch eShop

UNO®, the beloved card game, is coming to the Nintendo Switch system with exciting new features. Players can now race against friends to see who can empty their hand first in Classic Play, or you can customize your experience with a variety of unique and exciting House Rules. For even more fun, the new Emote system allows players to share the joy of victory – or the agony of defeat.

I honestly have no idea if UNO is well known in Japan like it is here in the states. I don't think many people here would grab the demo, since most of us know how UNO works!
