Well, that depends on whether you’re talking about the Caesars Slots app by Playtika or a Caesars Slots machine from a software provider like RTG.
In the case of the former — no, you can’t. The Caesars Slots app is a simulated gambling game, and it offers only their virtual currency.
However, if you’re thinking about the latter, then yes. Like most other slot games, all you have to do is deposit some money and play.
