Casinos are spending more and more money on “free play” promotional credits, which lure players into the casino only to lose all the money from the credit plus some of their own cash. Casinos figure that if they send you a $25 free play credit and you come in to the casino and cash it in, by the time you leave you’ll have given back well over that $25. That is part of the reason why, according to this Press of Atlantic City story, casinos are now spending 40 cents of every dollar in profit on these promotional credits, to lure you in and take their money back.
