You will need two coins, 2 shot glasses, 2 double shot glasses (Or a smaller cup) and 1 normal sized cup. You need to set up the glasses in a diamond shape with the smallest shot glasses either side then slightly larger shot glasses in between, then the large cup in the center. Each player should stand at each side of the diamond.
Each player throws their coins trying to get them in the glasses, racing to make it into all three in a row from smallest to largest. If the coin goes in the glass out of order you must fill it with a drink of your choice and drink it, then start again. Once a player gets three in a row from smallest to largest the opposing player must fill the large cup and drink it all. (Make sure you take the coin out first) Then the game can be restarted.
