In Up & Down players try to have the best combination of cards at the end of the game. One can aim at having all cards in his hand neutralised which gives 50 points. In all other cases one just has to add all values of the cards owned when the game ends. The gameplay is based on actions - one of which a player must choose in his turn: neutralising cards lying on the table, discarding or drawing. Number of cards drawn or discarded depends on what cards lie on the table.
One gameplay is very short but the rules suggest that the game should be played several times with results written down and summed up.
