Get 20 bucks in chips at the roulette. Bet 5 bucks on each 5-17-20-32. They are in the middle row. And next to each other in the wheel. If you win, let it roll once. Same bet. You will have to fill the non winning numbers. Either way, get up and go. No more than twice.
Blackjack and Craps take skills. But are fun, specially the Craps. Bet peanuts.
