Two people stand at the same end of a table or counter and put the two juice glasses down the table or counter at the same distance. Each player is assigned to a glass. Then each player gets a whole wack of quarters, around 30 is a good pile for each. Then someone sets the stop watch for 30 seconds and tells the players to go and each player tries to get the quarters in (just like the regular quarters game) and whoever has the most at the end of the 30 seconds wins and the loser has to take as many shots as there are quarters in the winners glass. You shouldn't run out of quarters cause in that time because you are bound to miss alot.
