Casino dice are usually required to be precision dice, which means that they must be manufactured to very tight specifications and tolerances. The casino dice size is also required to be consistent from die to die, so that one die does not roll any better than any other die.
There are several different ways to make precision dice, but the most common method is to start with a block of material that is precisely cut to size, and then each face is milled smooth. The next step is to drill a small hole in each corner of the block, and then insert dowels into the holes.
The dowels are used to align the block during the milling process, and they also create slots for the placement of the pins that will be used to mount the faces onto the block.
Once the slots have been milled, the faces can be glued into place. After the glue has dried, the pins can be inserted into the slots and the entire assembly can be given a final coating of lacquer or paint.
The finished casino dice will have sharp edges and flat faces, and they will all be exactly the same size. The size of casino dice is usually specified in millimeters, so it is important to know how many millimeters are in an inch before ordering them.
Most casinos use six-sided dice, but there are some that use four-sided or eight-sided dice as well. The size of the casino dice will depend on what game you are playing, so it is important to ask your dealer or croupier what size you need before you place your bet.
In conclusion, casino dice come in a variety of sizes that are all created equal in order to provide fairness during gameplay. Casino dice size is typically specified in millimeters, with six-sided dice being the most popular type used in casinos worldwide.
