Question:  What is the difference between Type A and Type B dice?

There are a few casinos that utilize different colors such as amber, green, purple, and even black. They also will use either "A" or "B" type dice, sometimes called "upside-down dice".

Every once in a while you will see a pair of red dice with something different about them, something that looks a little odd. Check out the pips (dots) on the dice. The answer is in which way are the 2 pip and the 3 pip are pointing.

If the 3 pip and the 2 pip are forming an arrow toward the 6 pip, these are called "type A dice." If the 2 pip and the 3 pip form an arrow toward the 1 pip, these are the "type B dice."

In the pictures below, picture #1 shows Type A on the left side. Notice the 3 and the 2 forming an arrow toward the 6. On the right is a Type B dice. On this die, the 2 and the 3 forming an arrow toward the 1.


In picture #2, you see the 3V set on an "A" type dice and a "B" type dice. Notice the dice on the left side form an arrow away from the shooter and the dice on the right side form an arrow toward the shooter.


Both sets of dice are on the same axis and that is why they are sometimes known as upside down dice. Most of the casinos in Las Vegas use "type A" dice. Occasionally you will find "type B" on certain shifts, but you should never see them mix together in the same bowl.

It is important that you are aware of these two types of dice. If you are setting the 3V set, and know that the V points away from you, but now you see the V pointing straight at you, it may take you out of your game.

Another 20 minute roll!  I think between that little modification and adopting your betting tactics, that this will work well in the long run.  Thanks again!  - Bill -
