Party games Musical chairs
Place a number of chairs (one less than the total number of game players, i.e. 10 chairs for a group of 11) in a room, back to back. Start to play some music and the participants walk in a cirlcle around the chairs, hands behind their backs. When the music suddenly stops, you have to quickly get a chair to sit down on. If two people sit down on the same chair, one of them has to find another free chair. The person who has no chair when they are all taken is out of the game.
Remove one chair and start the music again. The game continues until there is only two people and one chair left. The person who gets this last remaining seat as the music stops wins the game.
