Yes, Alex, there’s no real need to win; just convert one type of chip into another, constantly betting on the same thing, like an even number, for example. If you want to buy something specific, that’s fine.
If you want to be slightly in the positive, you can try gradually increasing your bet after losing several times in a row, but then you risk losing your money faster than you win.
If you don’t have a goal to buy something in the casino shop, I wouldn’t play at all.
