Ninja - the rules according to an outside observer

Ninja is a minor contact game where the players take turns making single 'ninja' type moves with the goal of making hand to hand contact thus removing competitors out of play.

• The game starts with two or more players standing in a circle.
• The order of play appears to be tied to the initial start position and the order of the players in the circle..
• After all players bow  and say 'bong' simultaneously, they all jump into initial 'ninja' poses/stances.
• Then, one at a time, they make defensive, offensive, or strategic moves.
• Defensive moves, move their hands (the targets) into positions where they are harder to 'hit'.
• Offensive moves a player in such a way to 'hit' (touch) the opponents hand.  The opponent may make one smooth defending move to prevent being hit.  after the move, the player freezes in the position where the hands would have hit until either their next term or a defensive move is required.  
• Strategic moves encourage the opponent to move into position that is easier to attack.
• The player is out when either one of their hand was hit or (if playing a variation of Ninja) when both hands have been hit.  (The hit hand becomes immobilized) 
• The game is over when only one ninja is left
