Danish Clapping Game

Best played with 2 players to begin with, though you can work up to more

Players stand facing each other. Play progresses rhythmically:

Both players clap their thighs
Both players pick a direction (left, right, up) and move their hands in that direction
Both players clap their thighs
If both players moved their hands in the same direction the last time, they must now high five each other with both hands. If a player fails to high five their partner, they are out of the game and the other player wins. Otherwise play continues, repeating the above steps.

Generally play starts slow, and ramps up in tempo until one player fails to high five when they should have done.

If playing with more than 2 players, the rules are the same but you now have to pay attention to more people. e.g. in a 3 player game players stand in a triangle, and when 2 people move their hands to the same point of the triangle those 2 players high five. When all 3 people move their hands up, all 3 players have to high five (left hand with the player on your left, right hand with the player on your right).

Instead of pointing in one of the 3 directions after clapping their thighs, the group decides on 3 specific poses to strike. Otherwise the same rules apply. For some reason I find this version a lot harder than the original.
