A: Inserting your slot club card into the machine enables the casino to track how many coins you run through the machines and that determines how many points you collect. Those points can be redeemed for meals, merchandise and other freebies. Therefore it is smart to accumulate points while you’re playing, but never play just to get points. Casinos operate slot clubs for only one reason, they want to entice players to wager more, play longer and lose more. Don’t fall into that trap.
