Have players pick a partner (preferably one they do not know). They will need to find out their partner’s name before each round. To play – face each other either face-to-face or in fencing ‘en-guard’ position and pretend your right hand is a fencing foil with your index finger pointing out as the foil tip. Stand far enough apart that you are crossing wrists with your opponent partner. The object of the game is to poke the other player first with your finger saber. Those who have been poked sit down and the partner that has won finds a new partner and so forth until it comes down to two and one will be the ultimate champion.
You could describe it as using light sabers to appeal to younger audiences (or even older ones :-))
