Registered Amusement Devices

Iowa Code chapter 99B.10 requires that all Electrical and Mechanical Amusement devices be registered with the Department of Inspections and Appeals (DIA). An amusement device subject to registration shall meet the following requirements:


  • A prize of merchandise exceeding $50.00 in value or cash shall not be awarded for use of the device.

  • A device shall not be designed or adapted to cause or to enable a person to cause the release of free games or portions of games when designated as a potential award for use of the device.

  • An amusement device shall not be designed or adapted to enable a person using the device to increase the chances of winning free games or portions of games by paying more than is ordinarily required to play the game.


The Department has adopted two sets of rules dealing with the general provisions of amusement devices [481 IAC 104] and registered amusement devices [481 IAC 105]. Additionally, a copy of Iowa Code Chapter 99B is available from this web page.
