Normally, you need three items for the device to be a gambling device, chance, consideration, and reward. There must be payment for consideration to win, and you need a chance to win. Since the device has controls for the rention percentage, that leans towards these are not gambling devices, since jurisdictions can differ. However, it is not exactly a skill device, either. There is an option to convert it to skill based, but I doubt an operator anywhere used that option. That is also why the manufacturer put the effort for that on the operator to install, so that it likely wouldn't get installed.
