There is only one guaranteed way to win back $18,000. Assuming you go to the Casinos two days a week, each time you pay a $100 for entry. In one year, you would have spent $10,000 just on entrance fee. So for the next two years you stop going to the casinos, you would have saved $20,000, more than recover your losses. And if you have used the membership pass to go in, sorry you have to stay away for a much longer period.
