Go to the roulette table and keep betting on the same number.
If you lose all your money, restart the game. Repeat this until you win on the same number. Do not take out a loan. It takes some time to get on the number that you want. When you have won on the number that you have been betting on constantly you should end up with about $180,000. You will then have a choice to either bet on black or red. Use the money that you just won and bet huge sums on one of those colors. Sometimes it is wise to bet a little bit and other times it is wise to bet a huge lump sum. Once you have the desired amount of money, you can go to the tournaments in the back of the game. Once you are back there, there is not much to worry about until you are getting low on casino cash.
If you feel that you are about to run out then repeat the steps.
