Check out the payout odds for each bet and free odds table for charts, house edge and odds percentages information. If you would like to calculate the odds of rolling a certain combination, just take the number of possible combinations of that roll and divide it by the total number of possible outcomes.
For example, rolling a 7 has six combinations. Therefore 6 divided by 36 would be a 1 in 6 chance of rolling a seven. Alas, the odds of rolling a 2 or 12 would be 1 in Another way of thinking about the craps game is thinking that since there is a 1 in 6 chance that a 7 will be rolled, there is a 5 in 6 chance that a 7 will not be rolled.
So betting on a point number in this case or betting for the shooter to not roll a 7 is a great bet as 5 out of 6 rolls will not be a lucky seven.
For example, when you roll a single six-sided die, you can get six total outcomes: 1, 2, 3, 4, 5, or 6.
Every time you add a die, the number of total outcomes is multiplied by 6. You can use the formula for probability to calculate the probability of each possible roll.
By contrast, in "street craps", there is no marked table and often the game is played with no back-stop against which the dice are to hit.
Despite the name "street craps", this game is often played in houses, usually on an un-carpeted garage or kitchen floor.
The wagers are made in cash, never in chips, and are usually thrown down onto the ground or floor by the players.
There are no attendants, and so the progress of the game, fairness of the throws, and the way that the payouts are made for winning bets are self-policed by the players.
Each casino may set which bets are offered and different payouts for them, though a core set of bets and payouts is typical.
Players take turns rolling two dice and whoever is throwing the dice is called the "shooter". Players can bet on the various options by placing chips directly on the appropriately-marked sections of the layout, or asking the base dealer or stickman to do so, depending on which bet is being made.
The game is played in rounds and these "Pass" and "Don't Pass" bets are betting on the outcome of a round. The shooter is presented with multiple dice typically five by the "stickman", and must choose two for the round.
The remaining dice are returned to the stickman's bowl and are not used. Each round has two phases: "come-out" and "point".
Dice are passed to the left. To start a round, the shooter makes one or more "come-out" rolls. The shooter must shoot toward the farther back wall and is generally required to hit the farther back wall with both dice.
Casinos may allow a few warnings before enforcing the dice to hit the back wall and are generally lenient if at least one die hits the back wall.
Both dice must be tossed in one throw. If only one die is thrown the shot is invalid. A come-out roll of 2, 3 or 12 is called "craps" or "crapping out", and anyone betting the Pass line loses.
On the other hand, anyone betting the Don't Pass line on come out wins with a roll of 2 or 3 and ties pushes if a 12 is rolled. Shooters may keep rolling after crapping out; the dice are only required to be passed if a shooter sevens out rolls a seven after a point has been established.
A come-out roll of 7 or 11 is a " natural "; the Pass line wins and Don't Pass loses. The other possible numbers are the point numbers: 4, 5, 6, 8, 9, and If the shooter rolls one of these numbers on the come-out roll, this establishes the "point" — to "pass" or "win", the point number must be rolled again before a seven.
The dealer flips a button to the "On" side and moves it to the point number signifying the second phase of the round.
If the shooter "hits" the point value again any value of the dice that sum to the point will do; the shooter doesn't have to exactly repeat the exact combination of the come-out roll before rolling a seven, the Pass line wins and a new round starts.
If the shooter rolls any seven before repeating the point number a "seven-out" , the Pass line loses, the Don't Pass line wins, and the dice pass clockwise to the next new shooter for the next round.
Any single roll bet is always affected win or lose by the outcome of any roll. While the come-out roll may specifically refer to the first roll of a new shooter, any roll where no point is established may be referred to as a come-out.
By this definition the start of any new round regardless if it is the shooter's first toss can be referred to as a come-out roll.
Any player can make a bet on pass or don't pass as long as a point has not been established, or come or don't come as long as a point is established.
All other bets, including an increase in odds behind the pass and don't pass lines, may be made at any time. All bets other than pass line and come may be removed or reduced any time before the bet loses.
This is known as "taking it down" in craps. The maximum bet for Place, Buy, Lay, Pass and Come bets are generally equal to table maximum. Lay bet maximum are equal to the table maximum win, so if a player wishes to lay the 4 or 10, he or she may bet twice at amount of the table maximum for the win to be table maximum.
Odds behind Pass, Come, Don't Pass and Don't Come may be however larger than the odds offered allows and can be greater than the table maximum in some casinos.
Don't odds are capped on the maximum allowed win some casino allow the odds bet itself to be larger than the maximum bet allowed as long as the win is capped at maximum odds.
Single rolls bets can be lower than the table minimum, but the maximum bet allowed is also lower than the table maximum. The maximum allowed single roll bet is based on the maximum allowed win from a single roll.
In all the above scenarios, whenever the Pass line wins, the Don't Pass line loses, and vice versa , with one exception: on the come-out roll, a roll of 12 will cause Pass Line bets to lose, but Don't Pass bets are pushed or "barred" , neither winning nor losing.
The same applies to "Come" and "Don't Come" bets, discussed below. A player wishing to play craps without being the shooter should approach the craps table and first check to see if the dealer's "On" button is on any of the point numbers.
In either case, all single or multi-roll proposition bets may be placed in either of the two rounds. Between dice rolls there is a period for dealers to make payouts and collect losing bets, after which players can place new bets.
The stickman monitors the action at a table and decides when to give the shooter the dice, after which no more betting is allowed.
When joining the game, one should place money on the table rather than passing it directly to a dealer. The dealer's exaggerated movements during the process of "making change" or "change only" converting currency to an equivalent in casino cheques are required so that any disputes can be later reviewed against security camera footage.
The dealers will insist that the shooter roll with one hand and that the dice bounce off the far wall surrounding the table.
These requirements are meant to keep the game fair preventing switching the dice or making a "controlled shot". If a die leaves the table, the shooter will usually be asked to select another die from the remaining three but can request permission to use the same die if it passes the boxman's inspection.
This requirement exists to keep the game fair and reduce the chance of loaded dice. There are many local variants of the calls made by the stickman for rolls during a craps game.
These frequently incorporate a reminder to the dealers as to which bets to pay or collect. Rolls of 4, 6, 8, and 10 are called "hard" or "easy" e.
Hard way rolls are so named because there is only one way to roll them i. Consequently, it is more likely to roll the number in combinations easy rather than as a double hard.
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.
The fundamental bet in craps is the pass line bet, which is a bet for the shooter to win. This bet must be at least the table minimum and at most the table maximum.
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.
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.
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.
Like the Pass bet, this bet must be at least the table minimum and at most the table maximum. 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 , 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.
If a player chooses to remove the don't pass line bet, he or she 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, There are two different ways to calculate the odds and house edge of this bet.
The table below 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.
If a 4, 5, 6, 8, 9, or 10 is thrown on the come-out roll i. 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 of 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 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 x or even unlimited odds.
A variation often seen is "X 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.
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. However, the odds bet cannot be made independently, so the house retains an edge on the pass line bet itself.
If a player is playing don't pass instead of pass, they may also lay odds by placing chips behind the don't pass line. If a 7 comes before the point is rolled, the odds pay at true odds of 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 5x odds table, the maximum amount the combined bet can win will always be 6x 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 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. A Come bet can be visualized as starting an entirely new pass line bet, unique to that player.
Like the Pass Line each player may only make one Come bet per roll, this does not exclude a player from betting odds on an already established Come point.
Players may bet both the Come and Don't Come on the same roll if desired. 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 thing as a pass line bet.
A player making a Come bet will bet on the first point number that "comes" from the shooter's next roll, regardless of the table's round. If a 7 or 11 is rolled on the first round, it wins.
If a 2, 3, or 12 is rolled, it loses. If instead the roll is 4, 5, 6, 8, 9, or 10, the Come bet will be moved by the base dealer onto a box representing the number the shooter threw.
Thanks for your kind words. Here are my answers. Assuming the player keeps his odds on during a come out roll then the overall house edge does not change if the player adds come bets, backed up with the odds.
However if the player keeps the odds off, which is the default rule, then the overall house edge will actually go up slightly by adding come bets.
That is a good question. It is obviously more fun to go with the crowd than against it. The question is why does the crowd favor the pass line?
Perhaps it is just tradition. Good question. You will always have a bet on the pass or come. This is the probability that by looking back at old rolls you will find a 4 before a 7.
This average will not true at the beginning, while you are getting in to the game. It will only apply after all point numbers and the 7 have already been rolled at least once.
So if the player rolls a seven on a come out roll any come bets will lose and odds on come bets will be returned. The answer depends on how we define the house edge.
If we define it as expected loss to total bets made then turning the odds off would not matter. This is because the player is still betting the odds and it still counts as a bet even if it is returned as a push.
However if you define the house edge as expected loss to bets resolved then turning the odds off on a come out roll does indeed increase the house edge.
I wrote a computer simulation to determine this effect. Assuming the player takes fives times odds then turning the odds off on come out rolls increases the ratio of losses to total bets resolved from 0.
So if you want to maximize your return on bets resolved then leave those come odds turned on. Just a coincidence I assure you.
In fact I would argue the house edge in all casino games must be a rational number because there are a limited number of possible outcomes in all games, resulting in a house edge of a perfect fraction.
Therefore the two numbers can not be equal. The square root of 2 is 1. Thanks for the compliment. I recommend taking the match play. That match play is worth about 48 cents on the dollar.
The reason I favor that over blackjack is that blackjack has a lower probability of winning, thus reducing the value of the match play.
For further explanation please see my October 30 column. To confirm their math I made the following table, based on a field bet paying 3 to 1 on a So the house edge is indeed.
Mensa Anything but Seven Combo Number Probability Field Place 5 Place 6 Place 8 Win Return 2 0. However, in this case the player is only keeping the place bets up for one roll.
This significantly reduces the house edge on the place bets from 4. For you purists who think I am inconsistent in measuring the house edge on place bets as per bet resolved or ignoring ties then I invite you to visit my craps appendix 2 where all craps bets are measured per roll including ties.
Let's call x the expected number of rolls per shooter. Likewise If the player rolls a 5 or 9 on the come out roll the expected number of additional rolls is 3.
The probability that player will not seven out is 1 - 0. As I argue in my sports betting section betting NFL underdogs at home against the point spread also has resulted in a historical advantage.
So x odds in craps is still one of the best bets out there, but not the very best. Yes, 0. I agree that this is a very bad decision and poor advice from the dealers.
Taking "no action" is the same as trading it for a bet with a 1. So this decision costs the player To any dealers encouraging this I say shame on you.
Low Bet Total Combinations Probability Pays Return Hard 6,8 2 0. The fewer the sevens the greater the odds favor the pass line bet.
The following table shows the house edge according to the percentage of sevens, assuming the probability of all other numbers is proportional to the fair probability.
I get a lot of questions about combinations of craps bets. Your mistake is that both bets are not resolved all of the time. When you win either the 6 or 8 you are taking the other bet down, which brings down the expected loss because you are betting less.
So your math is right but you are comparing apples to oranges. There are various ways of using cards in place of dice and still have the odds exactly the same.
One way is to use two separate decks, thus there is no effect of removal. Another way is to have a 7-card deck, featuring the numbers 1 to 6, plus a seventh "double" card.
