Mighty Payloader, Crompton Penny Falls and Sweepstakes Machines.
The Mighty Payloader, Crompton Penny Falls and Sweepstakes machines are similar in their operation. The district court described the operation of those machines in the following manner:
The Mighty Payloader contains a blade which constantly and steadily moves across the playing surface. On the playing surface are tokens, prizes and coins. At the front of the machine is a coin slot. When the player inserts a coin through the coin slot onto the playing surface, the coin may land on the playing surface, be pushed by the moving blade and thereby push one of the tokens, coins or prizes on the playing surface into the dispensing bin. The player has some control over where his coin lands on the playing board. Since the spot where the coin lands totally controls whether the player wins, he has some, but not total, control over whether he wins or loses.
United States v. 28 "Mighty Payloader" Coin-Operated Gaming Devices, No. 79-2016 (W.D.Ark., filed May 18, 1979).
The district court found these machines were operated by insertion of a quarter and that the value of the prizes varies but some were worth at least $1.00. It also found there is a substantial element of chance involved in playing these games. We cannot say the machines are exempt as a matter of law under 26 C.F.R. § 45.4461-1(a).
