Let’s say you place $ 10 on the pass line and roll the dice, if you roll a 7 or 11 you win $ 10 and if you roll 2, 3 or 12 you lose $ 10. But what happens when the player gets any of the other numbers that can be rolled on a dice roll? Well, as mentioned above, that number becomes your point and you have to roll that number again before a 7 is rolled in order to win your pass line bet. Once the point is established, the dealer at each end of the table will move a marker in the square corresponding to their point number to let the players at the table know what their point is. You will notice that the marker being used has two different faces, one is black with the word “off” and the other is white with the word “on”. Before any point is established, the marker is held in the “No Come” box with the black side up until its point number is rolled, at which point the dealer will flip it over showing the white face and move the illuminated button within the area of the mat that contains your stitch number.
Therefore, if on his opening roll he rolls for example a 4, the dealer will simply change the indicator with the white side up where it can be read “on” and place it in the box of number 4. This indicates that the 4 is the point number and you will continue to roll the dice, no matter how long it takes, until you get a 4, which will make you the winner of the bet, or a 7, which will make you lose the bet. Remember that once your point number is established, you will not be able to withdraw your pass line bet until you either win (by rolling your point) or lose (by rolling a 7). The reason for this is that on the come-out roll the pass line bettor has the advantage because there are eight ways to win (which are equivalent to the different combinations of the dice values to roll a 7 or an 11), that is : 1-6, 6-1, 2-5, 5-2, 3-4 or 4-3 for a seven and 5-6 or 6-5 for an eleven; and only 4 ways to lose (the different combinations that exist to get a 2, 3 or a 12), which are: 1-1 for a two, 1-2 or 2-1 for a three, and 6-6 for a twelve. In case a point number is rolled, no matter what number it is, then there is more chance of losing than winning and this is the reason why such a bet is not allowed to be withdrawn.
Now, imagine if you were allowed to withdraw your bet, it would be enough for all the players to wait for the initial roll of the dice and if they don’t win, they would simply retract their bet, which of course would give them a great advantage over the house and this it is something that, as we already know, will never happen and that is why you cannot withdraw your bet.
