dnup (Danish)

Your goal in dnup is to empty your hand of cards.

Each player starts with eight or ten cards in hand, each card having different numbers (from 1-10) at the top and bottom, e.g. 1 and 7. Pick up all your cards at once; you may rearrange the cards from left to right at any time, but you may not rotate them. On a turn, first discard any cards on the table in front of you, then you can:

1. Play cards from your hand.
2. Add a card on the table.
3. Take cards from the table.
4. Flip all the cards in your hand.

When you play cards, you can play one or more cards of the same value but if you play as many cards as another player has in front of them, your cards must have a higher value. If you outplay someone, e.g. by playing two 5s when they have two 2s, they must flip their cards and then return them to their hand.

When you add one card, you add a card of the same value to someone else’s played cards but if that player would now have the same number of cards as a third player, the third player’s cards must have a lower value, in which case they rotate them and return them to their hand.

When you pick up cards from in front of another player, rotate them and then put them in your hand.

The first player to empty their hand scores 2 points, and the cards do not return to their hand even if they are beaten. The second player to empty their hand scores 1 point. Play several rounds until one player has at least 4 points; the player with the most points then wins.
