Probably with some market downsizing. It’d essentially be an arcade but with slots. The appeal might be to use large denomination machines, like with the apps - lots of zeros
Not only can’t you cash out these apps but the apps are basically charging for zeros. They give players the option of buying and playing $10,000 chips for $3.99 or you can get “value” instead by buying $1,000,000,000 chips for $99. Gameplay is the same in both just with more zeros
