Understanding and knowing the odds of the dice to get a certain outcome is the essence of Craps. If you are going to place real money wagers at a Craps table, it is essential for you to remember these odds. First of all, you will have a slight disadvantage when you place the Pass Line wager: the odds of winning are 970 out of 1980 times. Other bets that yield relatively good odds for craps players include the Pass Line and Don't Pass Line bets, where the house has only a 1.4% edge and less if you're playing with single or double odds. The Place Bet of 6 or 8 is also worthy of your chips because it only carries a 1.52% advantage for the casino.

Craps is a table game played with dice that is highly popular in land-based casinos. Although it can be played at online casinos, it is more fun and exciting at land-based casinos. Whenever you enter a land-based casino, you will find a table that has players around it screaming and yelling numbers — this is the Craps table. There are two types of Craps. One is casino craps. In this game, players at the Craps table are all betting against the house or the casino, which is why it is called Casino Craps. The second kind is called Street Craps, which is where players play against each other — it used to be played in the streets, hence the name.

Craps is a game of pure luck as it all depends on the dice and the numbers that are rolled. In this game, players will place wagers on the outcome of the two thrown dice. A player who throws the dice is referred to as the shooter. After the dice have been rolled, players will be paid according to the outcome. Some wagers need more than one roll, while other wagers can be settled after one roll. In this tutorial, we are going to discuss the payouts and the different wagers that can be placed at the Craps table as well as the rules players will have to follow while playing at the table.

Craps History

Evidence suggests Craps may have originated and evolved during the ancient Roman Empire. While in camp Roman soldiers used to carve the knuckles of pigs into cubes and would toss them over their shield. The term 'To Roll the Bones' originated from this game. Other theories claim Craps originated in the Middle Ages with the people in the Arabian deserts as they used to play a game that was quite similar to Craps called Hazard or Azzahr.

If you want to understand more about how odds work, see dice odds. You will be at a slight disadvantage with the Pass Line bet since the odds of the dice winning are only 970 times out of 1980. The edge against the dice passing works out as 1.414%. The craps payout chart below shows various payout statistics such as what kind of craps bets, true odds, payout odds and the total house edge after everything has been calculated through. Note that these payout odds in the chart listed below are not the same in every casino or on all craps tables. But unless you can influence the dice, the odds are always stacked against you in craps. The Pass Line bet is the most common wager on the table. When you bet a Pass Line, the natural house edge is around 1.42%. If the Pass Line bet wins, it is paid even-money – a ten dollar bet wins ten dollars.

The definitive rules of this game were founded in the early 1700′s by Montmort. The roll that had the lowest value was referred to as crabs. While many believe this is where Craps got its name from, others believe the word evolved from Crapeaud, which is the French word for toad. Other theories claim the French were trying to reclaim the game as their own and they took the English word Crabs and spelled it in French as Crabes. In the 1700′s, the game succeeded in crossing the Atlantic Ocean and reached Acadia, the French Colony.

In 1755, the French lost their colony and the people of Acadia relocated to Louisiana. They brought the French game Crabes to Louisiana, but the game had changed to Creps or Crebs. By the year 1842, Craps started to be the dominant term and is still the name that is prevalent to this day.

During World War II, the Street version of the game became very popular and was played by the soldiers who used their blankets as the gaming surface. There was no wall to stop the dice from rolling out so they used blanket rolls to prevent it.

It is also important to note that the Craps version in modern America was brought by in Bernard Xavier Philippe, who was not only a politician but a gambler too. His version of Craps had a flaw that allowed players to exploit the game by taking advantage of the wagering system or by using fixed dice. This problem was fixed by John H Winn who introduced a new wagering option: 'Do Not Pass'. This wagering option is used to this day at any casino that offers craps to its players around the world.

How to Play Craps

As mentioned before, there are two types of Craps, we are going to discuss the gaming procedure of the most commonly played Craps version, Casino or Bank Craps. This version is played at casinos, this is why in this game, players will place wagers against the casino. The payoffs of the game may differ from one casino to the next.

In this game, players will take turns in rolling the dice. As previously mentioned the player throwing the dice is called 'The Shooter'. Before the shooter throws the dice, players will place their chips on the bets they want. They will find the different bets on a piece of green cloth; this piece of cloth has different available bets printed on it. Players can therefore easily place their chips on the bets they want to wager on. Players can usually go ahead and place their chips but there are some wagers that require players to ask the croupiers before putting them.

In order for a Craps player to get the chance to throw the dice as the shooter, he has to be active at the table by placing bets on either the Pass line or the Do Not Pass line wagers. These bets are also sometimes referred to as Right & Wrong or Win and Don't Win bets.

Players will roll the dice and keep passing it on in a clockwise direction. The player who is throwing the dice, the shooter, will roll his dice until he loses by getting a 7 or until his round is completed. The dealer in this game, also known as the Stickman is the person who represents the casino. He is called a Stickman because he uses a stick to collect the chips and move the dice around. The Stickman will present the shooter with 5 different dice and the shooter chooses 2 of them. The remaining dice will be placed in a bowl.

There are numerous bet types that can be placed at the Craps table; we are going to discuss the most common one below, the Line Wager. The line wager contains two bets; they are called the Pass Line and the Do Not Pass line wagers. The first one is a bet that the shooter could win.

If the first roll which is also referred to as the come out dice roll lands on either a 7 or an eleven, then the dice shooter will win. If the dice is equal to 2, three, or 12, then shooter will lose. On the other hand, if the dice has any other outcome than the ones mentioned, this value will be called 'Point'. In this case, the shooter will have to throw the dice again.

If he succeeds in rolling the point value before rolling a 7, he will win but if he rolls a 7 before he rolls the Point value, he will lose. The other bet is called the Do Not Pass wager, it is the exact opposite. Both bets pay 1:1.

Craps Rules

The rules at the Craps table include the wagers and the payouts. Apart from these basic rules, there are also some other unwritten rules that casinos implement at the Craps table.

3. Players should toss the dice on the table. Not slide them.

4. If the thrown dice by some chance hits other players or the hand of the dealer and still lands on the table, it can be counted provided that the players have not interfered with the rolled dice. Some casinos may deem these as no rolls and request the player re-roll the dice.

5. At some casinos, players will be able to call bets. Calling bets means they can start placing bets while they are waiting for their chips — they will call the bet and place it when they get the chips. Casinos that don't allow such bets will have the words 'No Call Bets' printed on the table of the game.

6. Casinos have the right to ask Craps players to leave the table at any given time without having to give any specific reason.

7. Do no toss chips on the craps table. Place them slowly.

8. Whenever players are offered to be the shooter, they are allowed to hand it to any other players at the table.

Pro's Perspective: Craps Strategies and Tips

With John Grochowski

Players who take the house edge seriously will quickly come to the conclusion that only a few bets are worth taking. Pass or do not pass and come or do not come are the basics, and some players also like place bets on 6 or 8 despite a slightly higher house edge just so that they can get the most frequently rolled non-7s working for them.

One-roll Bets and House Edge

One roll bets aren't worth a second look. Why settle for an 11.1 percent house edge on any craps when you can bet pass at 1.41 percent? Given that a player is sticking with the best bets, the next question to arise often is, 'Should I take the odds?' The answer depends on your bankroll and bet size.

There is no house edge on the odds. Paying at true odds, they're a rare example of even bets in a casino. To take the odds, however, you must bet pass or come, or don't pass or don't come, and those bets do carry an edge. If you're a table minimum bettor, it's between you and your bankroll as to whether you take the odds.

The Reality of Craps Odds

Let's say you're at a table with a $5 minimum bet, and you bet that minimum on the pass line 100 times. You have $500 at risk. The 1.414 percent house edge means that at the end of the trial, the average house take from your $500 is $7.07.

Craps Dice Odds Chart

Now let's say you bet the $5 minimum on a pass and $10 in double odds. Per 100 trials, you risk $500 on a pass and $1,000 double odds. The odds are a break-even bet, so on average, the house take is zero, while the house take on your pass bets remains $7.07. When results deviate from average, you can have much larger wins when you take the odds, and also much larger losses. Your average loss comes back to that same $7.07 with or without odds.

Now let's say you increase your pass bet to $15 without taking odds. Your risk per 100 trials increases to $150, and your average loss increase to $21.21.

Advantages to Taking Odds

Craps Dice Odds Chart

Here's where it's to your advantage to take the odds. Instead of increasing your pass bet to $15, leave it at the table minimum of $5, then use the rest of your intended bet increase to take the odds. That leaves your average loss at $7.07 while opening the door to larger wins.
Many modern casinos offer more than double odds. Some offer up to 100x odds, and it's become increasingly common for American casinos to offer 3x, 4x, 5x odds, meaning you can make an odds bet of three times your pass or come bet if the point number is 4 or 10, four times on 5 or 9 or five times on 6 or 8.

Regardless of what odds the casino permits, the most advantageous play is to use the odds bet to keep your pass or come bet low, then to put more of your money on the higher-paying odds.

Craps Odds and Probabilities - Calculating Craps Combinations

Calculating craps odds and probability seems hard, but it's not as complicated as one might think. When calculating the probabilities of any gambling activity, the first thing one looks at is the number of potential outcomes. When rolling two six-sided dice, like you in a game of craps, there are 36 possible outcomes. (There are only 11 possible totals, 2 through 12, but there are 36 combinations that can result in those totals.)

There is only one way to roll a 2 (or a 12). Roll a 1 on each die (or a 6 on each die.) Since there are 36 possible combinations, and only 1 of those combinations can total 2, the probability of getting a 2 on a roll is 1 out of 36, or 35 to 1, as stated in odds terms. There are 2 ways to roll a 3 though - you can roll a 1 and a 2, or roll a 2 and a 1, so the probability of rolling a 3 is 2 out of 36. 2 out of 36 is the same as 1 out of 18, which stated in odds terms is 17 to 1.

Here's a chart outlining the possible combinations, how many ways each total can be rolled, and what the odds are for each total.

Since there are 36 possible combinations, and only 1 of those combinations can total 2, the probability of getting a 2 on a roll is 1 out of 36, or 35 to 1, as stated in odds terms. There are 2 ways to roll a 3 though - you can roll a 1 and a 2, or roll a 2 and a 1, so the probability of rolling a 3 is 2 out of 36. 2 out of 36 is the same as 1 out of 18, which stated in odds terms is 17 to 1.

Here's a chart outlining the possible combinations, how many ways each total can be rolled, and what the odds are for each total.

Calculating the Odds in Craps

The formula used to calculate the odds of rolling a specific total in craps is actually pretty simple. Divide 36 by the number of combinations that will make that total. Since there are 6 combinations which will total 7, the probability is 36 divide by 6, or 1 in 6 chance of rolling a 7.

Converting this to odds is easy to. Odds are always stated as the number of possibilities of something not happening versus the number of possibilities of something happening. For every roll of 7 there will be 5 rolls that aren't 7.

Craps Probabilities and the House Edge

The house edge is the difference between what the house pays out on a bet and it's true odds. For example, if a casino pays $30 for a $1 bet that someone will roll a 2, it's making a profit, because the true odds are 35 to 1. To be a break even bet, the casino would need to pay out $35 on that bet. (And return the $1 bet.) But if a casino had nothing but break even bets, it wouldn't make a profit. Without a profit, they'd have no reason to exist, and one wouldn't get to play craps.

It's good to understand how probabilities and odds are calculated because not all bets have as high a house edge as other bets. If one understands the math behind the odds, one can then choose the better bets, the ones with the lowest house edge. Choosing the bets with the lowest house edge is just good craps strategy.
