What is Cup Game?

Context: The cup game is a children's clapping game that involves tapping and hitting a cup using a defined rhythm. The game can be played by many players seated around a table and is often played in large groups. Each player possesses a cup and in unison the players tap out the defined rhythm using their cups. It can be played competitively, where the rhythm speeds up in each "round", and a player making a mistake in the rhythm must drop out of the game, with a new "round" starting after each elimination, and game play continuing until only one player remains, with that player being the winner.
