I always use 'EM Game', 'Rifle Game', 'Chicago Coin', 'Electro Mechanical', 'EM Shooter', 'Midway Gun'. Not all of them work all of the time, but you know what Lincoln said.
"The available supply of gold and silver being wholly inadequate to permit the issuance of coins of intrinsic value or paper currency convertible into coin in the volume required to serve the needs of the people, some other basis for the issue of currency must be developed and some means other than that of convertibility into coin must be developed to prevent undue fluctuations in the value of paper currency or any other substitute for money of intrinsic value that may come into use."
