If a game is turned off outside of your normal business hours, that costs you money. Knowing when a machine is on or off, how much it is earning and at what time, can be a major boost in plays and revenue. For example, wouldn’t it be great to know how often a bartender turns off a game because a ball is stuck? How about when a coin slot is jammed? Knowing when machines stop working — when it happens — can make a huge difference in your time and bottom line.
