The shooter establishes a point and then rolls that number again before rolling a seven. These are bets that a specific number will come up before a seven is rolled. The Field bet in Craps looks better than it is. If you bet the field, you win if the shooter rolls two, three, four, nine, ten, eleven and twelve. That seems like a lot of numbers, but there is a catch-they are the numbers least likely to be rolled according to the mathematics of probability.
Most casinos pay double on twos and twelves.
This is one of the rare bets in the casino that is paid at true odds with no edge to the house. Once a shooter makes a point, the player can take what is known as free odds. This bet is paid at the true odds of making the point, which means that the overall house edge on Pass, Don't Pass, Come, and Don't Come bets are lowered when you take odds. Many casinos allow you to take double or triple your bet on free odds, which lowers the edge even more. Sometimes, you'll even see 100 times odds.
