Why Seven Sits at the Center of Craps
Two dice have 36 equally likely ways to land, but their totals are not equally likely. A seven can be made six ways: 1–6, 2–5, or 3–4, with either die able to show either number. By contrast, a two has only one combination, and a twelve has only one. That makes seven the most frequent total over many rolls, with a one-in-six chance on any single roll.
How That Shapes a Hand
In the common pass-line bet, the first roll is called the come-out roll. A seven or eleven wins immediately; a two, three, or twelve loses. If the shooter rolls 4, 5, 6, 8, 9, or 10, that number becomes the point. The shooter keeps rolling until either the point appears again, winning the bet, or a seven appears, ending the hand with a loss for pass-line bettors.
That second stage is where seven’s many combinations matter most. The point must be repeated before a seven arrives, and the dice give seven more chances to appear than any individual point number. Different point numbers have different odds because they, too, can be formed in different numbers of ways.
Likely Is Not Guaranteed
A one-in-six chance does not make a seven “due” after a run without one: each roll starts fresh. But over a long stretch of throws, sevens tend to accumulate more often than any other total. Craps turns that simple imbalance into the rhythm of the game: the same total that can settle a pass-line bet immediately on the opening roll can end it on a later one.
