make sidebets in the casino , it works.. no shit..
like bet on the betters..
Watch the big roller tables , and bet with someone else watching the person will lose.. start them off low with a few $200 bets betting they will win , and let him win a few then go for a grand to lose
p.s. if you lose refuse to pay , say "oh shit left the cash in the car" , the casino isnt going to enforce an illegal private side bet.
p.s.s. this could get you killed
