In my country playing those games you need to exchange for special slot coins then a little bit late with fiat coins about the cost 1peso I think US was around 0.25cents. So in the end kids in those days or you become super pro at that game an only spend one coin or ended spending the money of the groceries 🤣 or in the case of my country for the tortillas 😂 between 10 to 20 pesos, around 1usd of today's.
