The Iowa Lottery plans to test-market machines that’ll offer a new spin on a familiar product in six cities early next year. Lottery spokeswoman Mary Neubauer says the pull-tab ticket vending machines have attached video monitors.They vend traditional tickets but the results of the ticket will be displayed on the monitor. Each ticket will cost between 25-cents and two-dollars. The top prize offered is 600-dollars. Neubauer says the machines will dispense the traditional pull-tab game tickets but with a new twist people should like. You can still play the ticket and get the results on the screen.Neubauer says the games will be installed only in places where people who are underage would -not- have access to them — businesses like taverns and V-F-W halls. The machines will be tested out, starting as soon as February, in Des Moines, Waterloo, Cedar Falls, Center Point, Vinton and Marion. After the six-month test run, Neubauer says lottery officials will weigh two main factors: how reliable the machines have been and how much revenue they generated.
