It’s not surprising that DD Mau‘s copy calls its own game “the newest, hottest card game to hit the market since UNO”. The game is, essentially, UNO.

After you play a card, you can play additional cards of the same number on your turn. And it’s got a bit of a nicer theme, some tween-age graphics, and a few extra control cards.

Update: The designer/publisher has added a comment.
