Play your cards well! dnup (down up) is a fast-paced, imaginative card game where you build rows of increasing or decreasing numbers, while your goal is to be the first to get rid of all your cards. The special feature of the game lies in the double-sided cards: each card has two possible values, top and bottom, and when you draw a card, you must turn it over, so its value changes immediately and often fits in a completely different place than you originally thought. You can change the situation in your turn in several ways: you can start a new row, expand other people's already played rows, take away a played row, or rearrange the cards in your hand. It's not enough to just pay attention to your own cards: other people's sets are also an opportunity, and a well-timed addition or removal can rearrange the table in seconds. The game continues until the second player also empties his hand, after which points are scored.
