Craps is a very popular dice game in casinos especially at US soil. In Europe it is not that popular. Online craps is available on all major online casino softwares. Unfortunately Craps is usually excluded from the games that count towards bonus wagering requirements because it has some low house edge bets and it is possible to bet simultaneously on opposite outcomes, greatly reducing risk. However, Craps can be used in “stickying up” the bonus which means trying to increase bankroll with the bonus before starting to complete wagering requirements.
Craps Rules and Gameplay
This presentation covers only the two betting options available on Craps with the lowest house edge. Craps has many other betting options in addition to them if player prefers more risky bets.
After placing your bets on certain area of the table, two dice are rolled and depending on the sum of the dice, your bet either wins, loses or remains unsolved. The following table shows the probability of having each total in Craps:
Pass bet: To make this bet you place the bet at the “pass line”–area of the table. If you roll 7 or 11, the bet wins and pays 1:1. If 2,3 or 12 is rolled, the bet loses. If anything else (4,5,6,8,9,10) is rolled, this number becomes “active” and it is called the point. For example if 8 is rolled, then the point is 8. After this the dice is rolled until either 7 or the point is rolled. This bet wins if the point is rolled before 7 and loses if 7 is rolled before the point.
Pass Odds bet: This is a no-house edge additional bet that the player should always take to reduce the total house edge of the game. After the point is made in previous bet, the player may stake additional bet, which will win if the point is rolled before 7. This bet pays out true odds, and has no house edge. You can usually bet only maximum 3 times the pass bet. If you take the maximum Pass Odds bet (results in lowest house edge), the combined house edge is only 0.47%.
Don’t Pass bet: If you are familiar with the Pass bet this bet it the opposite of that bet. You place the bet at Don’t pass area of the table. The bet wins if 2 or 3 is rolled, loses if 7 or 11 is rolled and the bet is returned if 12 is rolled. If anything else (4,5,6,8,9,10) is rolled, this number becomes the point and the bet wins if 7 is rolled before the point is rolled again, and loses if the point is rolled before 7.
Don’t Pass Odds bet: Like Pass Odds bet you can usually stake maximum 3 times Don’t pass bet on this bet. The bet pays true odds without house edge if 7 is rolled before the point. The combined house edge with Don’t pass bet + maximum Odds bet is 0.45%.
House Edge and Optimal Strategy
The lowest house edge bets are the bets mentioned above. The difference in house edge is small, but Pass bets + odds have higher variance than Don’t pass bets + odds so the choice depends on your target. The optimal strategy is to make the maximum Odds bet every time because it makes the combined house edge as small as possible.
Craps Introduction Video
Casino softwares have some differences with the maximum Odds bet you can make resulting in slight different house edges between different softwares.
The standard deviation of Pass bet & Don’t pass bet is 1.00 which is equal to a coin flip. With maximum 3x Odds bet the standard deviation for the combined bet is 3.84 for the Pass + Odds bet and 2.90 for the Don’t pass + Odds bet. It is important to not make too large Pass/Don’t pass bets so that you can always take the maximum Odds bet.
As there are virtually no Craps bonuses available, the tables for results over bonus wagering requirement are not listed here.
