The basic game of craps is very simple. The most fundamental bet is the "pass line" wager, which almost everyone on a given game may make. On the first roll of the two dice (the come-out roll), the pass line bettors, or "right" bettors win by rolling either a 7 or 11 (a natural). If the shooter, or any other player, has a bet on the pass-line, he would win on the natural. Rolling craps (2, 3, or 12) loses immediately for the pass line bettor. Any other number (4, 5, 6, 8, 9, or 10) is called the point. To win, the pass-line bettor must roll the point number again before rolling a 7. If a 7 comes up before the point number, the shooter has sevened-out and the dice fail to pass. The shooter relinquishes the right to shoot when he or she sevens out, and the player to the left shoots next, beginning a new come-out sequence.
On any come-out roll, the shooter or any other player may also choose to place a don't pass wager, betting against the dice. This method, called "betting wrong," is by no means morally inferior to "right betting." In fact, the don't pass offers a lower house edge than pass line betting, and features the same free odds bet after a point is established. The bet works exactly like the opposite of the pass line wager, with the don't-pass bettor losing on the come-out when a natural is rolled. The don't bettor wins when a craps is rolled on the come-out, except on the roll of a barred craps, where the bet is a stand-off or push. Usually casinos bar the 2 or 12 craps, but beware a house which bars the 3 craps, as this practice doubles the house edge on the don't pass wager. The barred number is where the house derives its advantage by not paying the designated craps roll. Converse to pass-line betting, the wrong bettor wins on 7-outs and loses when a point is made.
