This even-money wager is the same as the Pass Line and can be made any time after the Come Out Roll.
After the point is established, the wager wins if a 7 is rolled and loses if the point is rolled again. If a 12 is rolled, the wager on the Don't Pass is a tie (bar). Any other number becomes the 'point.' You win if the shooter rolls the point again before rolling a 7 and lose if he rolls a 7 first.
