So, I met up with a friend at the casino the other week and talked him into playing roulette with me. He's a slots player, and has never played roulette before. So, he has no system and probably didn't know anything about the odds, etc.
Anyway, the minimum bet was $5 total. He played the minimum bet the entire time, betting only $1 on 5 different numbers. Started out with $20, and left with over $400!
While watching him play, I noticed if he didn't get a hit in severa spins, he would change out one of his numbers for a "hotter" number. Proof that it's best to play hot numbers. While this is a basic strategy, he didn't use progressions and never stuck with the same numbers that weren't hitting. Simple but effective. Pretty sure he's gonna be hooked now ;)
