Pure craps : only play the pass line and come bets with 10 x odds.
After the come out, every toss of the dice roll gets a fresh come bet, and then you take 10x odds. No props bets/horn bets. No hardways either.
It might be a boring way to play, but you can make a lot of money if the dice don't roll too funny.
Watched a guy win $150,000 in twenty minutes at the Wynn using a similar system with 5x odds. Anyone else play strictly this way? It's almost a sure thing.
