Does it Pay? No, it doesn't. Cash Slots is not giving away real prizes, so you won't get paid even if you meet the conditions. It's important to mention the developer's goal is to hook the player on the game for as long as possible.
Every time you use actual money to bet on the games, you will also receive real winnings. Moreover, you can even win money by playing online slots with bonuses and extra spins awarded by the casino.
