Players take it in turns. Player one places a number of coins in a pile, say 5 to start, on a receipt on the edge of a table or bar. The player then tries to whip the receipt from under the coins without knocking the coins over. On every successful attempt another coin is added to the pile. The winner is the person who can pull out the paper without knocking over the most coins.
