So here's what I was thinking. Y don't u make it to where it beeps or does something whenever u go on top of a playable card on uno. I know u should know what u are able to play anyway, but still. This would make it easier and make the game go faster. U could make 1 simple beep when u went on top of the card or a buzzer or something. It shouldn't be very hard to do. This would definitely make a good addition to the playroom.
