Get ready, set... done? In nimble, everyone plays at the same time and tries to play all their cards onto the three piles in the middle of the table as fast as possible. To do this, they must follow the guideline 'inside is the new outside'. The coloured circle of the topmost card on a pile determines the border colour for the next card that can be played. A round of the game can be over almost as quickly as it had begun, and if you snooze, you lose. But since the game only takes about five minutes, there is plenty of time for a rematch... and another one, and another one.
