If you love online craps, then you need to know the odds of rolling the dice. For you to comprehend how good your chances of winning are, it is of crucial importance for you to understand how often each dice roll is bound to show up on the table.

The reason the game of online craps is centred around the number 7 is that this is the number that rolls out the most. You can trust that online casinos have calculated the odds for each and every single roll of the dice, and knows its edge over the player for each bet.

How odds are calculated mathematically in online craps

Each die has six sides with six different values. In a game of online craps, two dice are rolled each time. Since there are six different numbers on the die, there could be a total of 12 different possible outcomes when they’re rolled out.

However, upon closer inspection, there are actually 36 different outcomes of the dice roll. Since there are two dice, one number can be rolled out in different ways. Similar to trying to calculate the odds of playing in a lottery, all various number combinations should be taken into consideration.

The one way to go about calculating the combinations is by starting at the low end of the rolls with the lowest number on the dice being one.

If two dice are rolled as one, the outcome would be two. That is just one possible roll. The next number would be three. In order to establish how many times this can be rolled out, we need to use a simple mathematical equation. This equation would produce this result: 2 +1 = 3. So the outcomes would be as possible:

Die 1 = 1, Die 2 = 2 or Die 1 = 2, Die 2 = 1

For a better example, let’s use the number 7 as an outcome. For us to get the number 7, we have three ways: 2 + 5, 3 + 4 and 1 + 6. To further calculate the number of times the outcomes can be rolled out, multiply it by two and you have six possible outcomes for the number 7 to be rolled out with two dice.

Knowing how to calculate the odds is important for you to know especially when it comes to the payouts for each given bet. Although winning a bet depends on what is rolled out, it does not mean that the odds are all the same for each point.

Being aware of this will play a part in your choice of increasing your stake on a bet. To calculate the percentage of your chance of rolling a specific number, just divide the number of outcomes by the total dice outcomes. For example, for the number 6, you would divide 6 by 36 x 100% = 16.6%

Although calculating odds and probabilities can seem a little daunting, it’s quite an easy task once you know how to break it down. You need to remember to first look at the number of potential outcomes, which is 36 and then to calculate the odds.

How to calculate probabilities and the house edge

The house edge in the game of online craps is essentially the difference between the payout on the bet and the odds. If a casino is paying €30 for a €1 bet that a player will roll a 2, it is making a profit, because the odds stand at 35:1.

In order for the online casino to break even, the casino would need to pay €35 on that bet. If the casino had only break even bets, it would make no profit and it would be out of business.

It is also good to know how the probabilities and the odds are calculated since not all bets have a high house edge attached to them. If you comprehend the simple maths behind these odds, you should be able to place better bets, ones with a lower house edge.
