The rules vary with the type of online crap game you are playing. It depends whether you are playing in opposition to the house or in a tournament online.
The rules when playing in opposition to the house
The rules of playing Crap in opposition to the house are simple. It is a simple game of throwing a pair of dice. The progress of the game depends upon the outcome from the two dice at the first throw. The name of the first throw is “come.” If the summation of the first throw of the two dice is two, or three or twelve, then it would be called “Craps,” and if you made a bet of “pass” then you would be losing it. If the summation of the two dice at the first throw is seven or eleven, then it would be called a “natural” and if you made a bet of “pass” then you would be winning it.
If the summation of the two dice at the first throw is other than two, three, seven, eleven or twelve, then it would be called a “point.” Then the dice would be thrown once again as long as the number of point or the number of seven appears at that point the round would be considered as over and a new set of come role is demanded. This sort of bets are called “bet of pass line,” “bet of do not pass the line,” “bet of place,” “bet of come” and the “bet of do not come.” These sorts of bets are played in opposition to the house.
The rules of playing in the online tournament
Playing in opposite to other players is quite different than playing in opposition to the house. The rules differ from site to site. Therefore, you need to go through the terms and conditions of the site prior to signing up for the site and begin to play.
The details of the amount you would need to invest to get in the tournament, the number of games that you would need to play in the tournament and the amount of winning prize are all given in the terms and conditions of the site of the Crap game.
