coin-pusher
n.— «The machines, versions of which are common in arcades, are called coin-pushers. The user drops in a coin, hoping that it will force more coins off the front of a shelf. But in the case of the illegal machines, the shelf was designed that more coins fell to the side, investigators said. That money was split 50/50 between the business and the distributor. The machine appeared to have also been designed so that it was harder for the coins to fall off the front.» —“Troopers Arrest Man In Illegal Coin Machine Case” in Omaha, Nebraska MSNBC Feb. 26, 2009.
