===Line bets===
{{Unreferenced section|date=April 2018}}
The shooter is required to make either a Pass line bet or a Don't Pass bet if he wants to shoot. On the come out roll each player may only make one bet on the Pass or Don't Pass, but may bet both if desired. The Pass Line and Don't Pass bet is optional for any player not shooting. In rare cases, some casinos require all players to make a minimum Pass Line or Don't Pass bet (if they want to make any other bet), whether they are currently shooting or not.

====Pass line====
The basic bet in craps is the Pass line bet, which is a bet for the shooter to win.<ref name=Scarne74/>{{rp|110}} This bet must be at least the table minimum and at most the table maximum.
* If the come-out roll is 7 or 11, the bet wins.
* If the come-out roll is 2, 3 or 12, the bet loses (known as "crapping out").
* If the roll is any other value, it establishes a point.
** If, with a point established, that point is rolled again before a 7, the bet wins.
** If, with a point established, a 7 is rolled before the point is rolled again ("seven out"), the bet loses.
The Pass line bet pays even money.<ref name=Scarne74/>{{rp|110}}

The Pass line bet is a contract bet.  Once a Pass line bet is made, it is always working and cannot be turned "Off", taken down, or reduced until a decision is reached – the point is made, or the shooter sevens out.<ref name=Scarne74/>{{rp|110}} A player may increase any corresponding odds (up to the table limit) behind the Pass line at any time after a point is established. Players may only bet the Pass line on the come out roll when no point has been established, unless the casino allows put betting where the player can bet Pass line or increase an existing Pass line bet whenever desired and may take odds immediately if the point is already on.

====Don't Pass====
A Don't Pass bet is a bet for the shooter to lose ("seven out, line away") and is almost the opposite of the Pass line bet.<ref name=Scarne74/>{{rp|110–112}} Like the Pass bet, this bet must be at least the table minimum and at most the table maximum.
* If the come-out roll is 3, the bet wins.
* If the come-out roll is 7 or 11, the bet loses.
* If the game is being played under "Bar-12" or "Bar Sixes":
** If the come-out roll is 2, the bet wins.
** If the come-out roll is 12, the bet is a push (neither won nor lost).
* Alternatively, if the game instead is played under "Bar-2" or "Bar Aces":
** If the come-out roll is 2, the bet is a push.
** If the come-out roll is 12, the bet wins.
* If the roll is any other value, it establishes a point.
** If, with a point established, a 7 is rolled before the point is rolled again ("seven out"), the bet wins.
** If, with a point established, that point is rolled again before a 7, the bet loses.
The Don't Pass bet pays even money.

The Don't Pass bet is a no-contract bet. After a point is established, a player may take down or reduce a Don't Pass bet and any corresponding odds at any time because odds of rolling a 7 before the point is in the player's favor. Once taken down or reduced, however, the Don't Pass bet may not be restored or increased. Because the shooter must have a line bet the shooter generally may not reduce a Don't Pass bet below the table minimum. In [[Las Vegas]], a majority of casinos will allow the shooter to move the bet to the Pass line in lieu of taking it down; however, in other areas such as [[Pennsylvania]] and [[Atlantic City, New Jersey|Atlantic City]], this is not allowed. Even though players are allowed to remove the Don't Pass line bet after a point has been established, the bet cannot be turned "Off" without being removed.  Players choosing to remove the Don't Pass line bet can no longer lay odds behind the Don't Pass line. The player can, however, still make standard lay bets on any of the point numbers (4, 5, 6, 8, 9, 10).

The casino chooses either Bar-2 or Bar-12, but not both. The push on 12 or 2 is mathematically necessary to maintain the house edge over the player.<ref name=Scarne74/>{{rp|111}} Other casinos allow the player to choose to either push on 2 ("Bar Aces") or push on 12 ("Bar Sixes") depending on where it is placed on the layout. Some older bank crap games used Bar-3 ("Bar Ace-Deuce"), which increases the house edge.<ref name=Scarne74/>{{rp|112}}

There are two different ways to calculate the odds and house edge of this bet. The summary table gives the numbers considering that the game ends in a push when a 12 is rolled, rather than being undetermined. Betting on Don't Pass is often called "playing the dark side", and it is considered by some players to be in poor taste, or even taboo, because it goes directly against conventional play, winning when most of the players lose.

====Pass odds====
If a 4, 5, 6, 8, 9, or 10 is thrown on the come-out roll (i.e., when a point is established), most casinos allow Pass line players to take odds by placing up to some predetermined multiple of the Pass line bet, behind the Pass line.  This additional bet wins if the point is rolled again before a 7 is rolled (the point is made) and pays at the true odds:<ref name=Scarne74/>{{rp|113}}
* 2-to-1 if 4 or 10 is the point,
* 3-to-2 if 5 or 9 is the point, or
* 6-to-5 if 6 or 8 is the point.

Unlike the Pass line bet itself, the Pass line odds bet can be turned "Off" (not working), removed or reduced anytime before it loses. In Las Vegas, generally odds bets are required to be the table minimum. In Atlantic City and Pennsylvania, the combine odds and Pass bet must be table minimum so players can bet the minimum single unit on odds depending on the point. If the point is a 4 or 10, players can bet as little as $1 on odds if the table minimum is low such as is $5, $10 or $15. If the player requests the Pass odds be not working ("Off") and the shooter sevens-out or hits the point, the Pass line bet will be lost or doubled and the Pass odds returned.

Individual casinos (and sometimes tables within a casino) vary greatly in the maximum odds they offer, from single or double odds (one or two times the Pass line bet) up to 100× or even unlimited odds.  A variation often seen is "3-4-5× Odds", where the maximum allowed odds bet depends on the point: three times if the point is 4 or 10; four times on points of 5 or 9; or five times on points of 6 or 8. This rule simplifies the calculation of winnings: a maximum Pass odds bet on a 3–4–5× table will always be paid at six times the Pass line bet regardless of the point.

As odds bets are paid at true odds, in contrast with the Pass line which is always even money, taking odds on a minimum Pass line bet lessens the house advantage compared with betting the same total amount on the Pass line only. A maximum odds bet on a minimum Pass line bet often gives the lowest house edge available in any game in the casino.<ref name=Scarne74/>{{rp|114}} However, the odds bet cannot be made independently, so the house retains an edge on the Pass line bet itself.

====Don't Pass odds====
If a player is playing Don't Pass instead of pass, they also may lay odds by placing chips behind the Don't Pass line. If a 7 comes before the point is rolled, the Don't Pass odds pay at true odds:<ref name=Scarne74/>{{rp|114}}
* 1-to-2 if 4 or 10 is the point,
* 2-to-3 if 5 or 9 is the point, or
* 5-to-6 if 6 or 8 is the point.

Typically the maximum lay bet will be expressed such that a player may win up to an amount equal to the maximum odds multiple at the table. If a player lays maximum odds with a point of 4 or 10 on a table offering five-times odds, he would be able to lay a maximum of ten times the amount of his Don't Pass bet.  At 5× odds table, the maximum amount the combined bet can win will always be 6× the amount of the Don't Pass bet. Players can bet table minimum odds if desired and win less than table minimum.

Like the Don't Pass bet the odds can be removed or reduced. Unlike the Don't Pass bet itself, the Don't Pass odds can be turned "Off" (not working). In Las Vegas generally odds bets are required to be the table minimum. In Atlantic City and Pennsylvania, the combine lay odds and Don't Pass bet must be table minimum so players may bet as little as the minimum two units on odds depending on the point. If the point is a 4 or 10 players can bet as little as $2 if the table minimum is low such as $5, $10 or $15 tables. If the player requests the Don't Pass odds to be not working ("Off") and the shooter hits the point or sevens-out, the Don't Pass bet will be lost or doubled and the Don't Pass odds returned. Unlike a standard lay bet on a point, lay odds behind the Don't Pass line does not charge commission (vig).

====Come bet====
A player making a Come bet is wagering on the first number that "comes" from the shooter's next roll, regardless of the table's phase. In other words, a Come bet can be considered as starting an entirely new Pass line bet, unique to that player.<ref name=Scarne74/>{{rp|112}} 
* If a 7 or 11 is rolled on the shooter's next roll, the Come bet wins.
* If a 2, 3, or 12 is rolled on the shooter's next roll, the Come bet loses.
* If a 4, 5, 6, 8, 9, or 10 is rolled on the shooter's next roll, the number becomes the "come-bet point".
** The Come bet will be moved by the base dealer onto a box representing the same "come-bet point" number the shooter threw.
** If, with the Come-bet point established, that number is rolled during this second phase, the Come bet wins.
** If, with the Come-bet point established, a 7 is rolled during this second phase, the Come bet loses.
** The player is allowed to take odds on the Come-bet point, just like a Pass line bet.

The Come bet pays off at even money, like the Pass line bet.<ref name=Scarne74/>{{rp|113}}

Come bets can only be made after a point has been established since, on the come-out roll, a Come bet would be the same as a Pass line bet. Like the Pass line bet, each player may only make one Come bet per roll; this does not exclude a player from betting odds on an already established come-bet point. The Come bet must be at least the table minimum and at most the table maximum. Players may bet both the Come and Don't Come on the same roll if desired.

Also like a Pass line bet, the come bet is a contract bet and is always working, and cannot be turned "Off", removed or reduced until it wins or loses. However, the odds taken behind a Come bet can be turned "Off" (not working), removed or reduced anytime before the bet loses. In Las Vegas generally odds bets are required to be the table minimum. In Atlantic City and Pennsylvania, the combine odds and Pass bet must be table minimum so players can bet the minimum single unit depending on the point. If the point is a 4 or 10, players can bet as little as $1 if the table minimum is low such as $5, $10, or $15 minimums. If the player requests the Come odds to be not working ("Off") and the shooter sevens-out or hits the Come bet point, the Come bet will be lost or doubled and the Come odds returned. If the casino allows put betting a player may increase a Come bet after a point has been established and bet larger odds behind if desired. Put betting also allows a player to bet on a Come and take odds immediately on a point number without a Come bet point being established.

The dealer will place the odds on top of the come bet, but slightly off center in order to differentiate between the original bet and the odds.  The second round wins if the shooter rolls the come bet point again before a seven. Winning come bets are paid the same as winning Pass line bets: even money for the original bet and true odds for the odds bet.  If, instead, the seven is rolled before the come-bet point, the come bet (and any odds bet) loses.

Because of the come bet, if the shooter makes their point, a player can find themselves in the situation where they still have a come bet (possibly with odds on it) and the next roll is a come-out roll. In this situation, odds bets on the come wagers are usually presumed to be not working for the come-out roll. That means that if the shooter rolls a 7 on the come-out roll, any players with active come bets waiting for a come-bet point lose their initial wager but will have their odds bets returned to them.

If the come-bet point is rolled on the come-out roll, the odds do not win but the come bet does and the odds bet is returned (along with the come bet and its payoff). The player can tell the dealer that they want their odds working, such that if the shooter rolls a number that matches the come point, the odds bet will win along with the come bet, and if a seven is rolled, both lose.

Many players will use a come bet as "insurance" against sevening out: if the shooter rolls a seven, the come bet pays 1:1, offsetting the loss of the Pass line bet.  The risk in this strategy is the situation where the shooter does not hit a seven for several rolls, leading to multiple come bets that will be lost if the shooter eventually sevens out.

====Don't Come bet====
In the same way that a Come bet is similar to a Pass line bet, a Don't Come bet is similar to a Don't Pass bet.<ref name=Scarne74/>{{rp|113}} Like the Come, the Don't Come can only be bet after a point has already been established as it is the same as a Don't Pass line bet when no point is established. This bet must be at least the table minimum and at most the table maximum. A Don't Come bet is played in two phases, just like the Don't Pass line bet.
* If a 2 or 3 is rolled in the first phase, it wins.
* If a 7 or 11 is rolled, it loses.
* If a 12 is rolled, it is a push, assuming that Bar-12 is being followed; if Bar-2 is being followed, 2 instead is a push and 12 wins, in the same way as described above for the variants of the Don't Pass bet.
* If, instead, the roll is 4, 5, 6, 8, 9, or 10, this sets the Don't Come point.
** The base dealer will move the Don't Come bet onto a box representing the Don't Come point, i.e., the number the shooter threw.
** The second phase wins if the shooter rolls a seven before the Don't Come point.

Like the Don't Pass each player may only make one Don't Come bet per roll, this does not exclude a player from laying odds on an already established Don't Come points. Players may bet both the Don't Come and Come on the same roll if desired.

The player may lay odds on a Don't Come bet, just like a Don't Pass bet; in this case, the dealer (not the player) places the odds bet on top of the bet in the box, because of limited space, slightly offset to signify that it is an odds bet and not part of the original Don't Come bet. Lay odds behind a Don't Come are subject to the same rules as Don't Pass lay odds. Unlike a standard lay bet on a point, lay odds behind a Don't Come point does not charge commission (vig) and gives the player true odds. Like the Don't Pass line bet, Don't Come bets are no-contract, and can be removed or reduced after a Don't Come point has been established, but cannot be turned off ("not working") without being removed.  A player may also call, "No Action" when a point is established, and the bet will not be moved to its point.  This play is not to the player's advantage.  If the bet is removed, the player can no longer lay odds behind the Don't Come point and cannot restore or increase the same Don't Come bet. Players must wait until next roll as long as a Pass line point has been established (players cannot bet Don't Come on come out rolls) before they can make a new Don't Come bet. Las Vegas casinos which allow put betting allows players to move the Don't Come directly to any Come point as a put; however, this is not allowed in Atlantic City or Pennsylvania. Unlike the Don't Come bet itself, the Don't Come odds can be turned "Off" (not working), removed, or reduced if desired. In Las Vegas, players generally must lay at least table minimum on odds if desired and win less than table minimum; in Atlantic City and Pennsylvania a player's combined bet must be at least table minimum, so depending on the point number players may lay as little as 2 minimum units (e.g. if the point is 4 or 10). If the player requests the Don't Come odds be not working ("Off") and the shooter hits the Don't Come point or sevens-out, the Don't Come bet will be lost or doubled and the Don't Come odds returned.

Winning Don't Come bets are paid the same as winning Don't Pass bets: even money for the original bet and true odds for the odds lay. Unlike come bets, the odds laid behind points established by Don't Come bets are always working including come out rolls unless the player specifies otherwise.
