Casino dice are one of the most vital pieces of equipment in a casino, and they are used for a huge number of games, with craps being the most popular. Casino dice are some of the most evolved pieces of equipment in a casino, having been made of bone and ivory originally, and in a number of shapes. With loaded dice being a large problem when it comes to casino games, and the number of different types of die available, we’ve put together a list of how casino dice are made and tested.
Modern gaming dice are generally maybe through a plastic injection moulding process, and the plastics that they are made from have to be hard in order to cope with the impact of regularly being thrown. They also need to be easily coloured as many different games require different types and colours of dice. Most dice tend to be made from thermoset plastic polymers, which are perfectly colourless – allowing pigments and dyes to be added. Other properties such as plasticizer are added to alter the physical properties of the dice. The pips/numbering system on the dice are a part of the mold itself which end up indenting the ice as they are made.
Casino dice are actually made very differently. They are actually machined, rather than molded, due to the incredibly tight federal mandates relating to how the casino dice are made. This is done in order to distribute the dice, and computer machines can do this far more precisely than a regular machine which uses a mould. The holes for the pips/numbers are actually drilled into each and every die, and then this hole is filled in with a coloured substance that is the exact same density as the plastic of the dice. This is done to ensure that there is no difference in either side of the dice, as with indents this would mean that the ‘6’ side would inevitably be lighter than the side with ‘1’.
In order to ensure that a die meets specified quality standards, quality control procedures generally take place. Prior to manufacturing certain physical and chemical properties of the incoming plastic raw materials are checked such as molecular weight determinations, chemical composition studies, stress-strain testing and impact tests. If any defective dice are found, they are removed from the production line and set aside for reforming. This ensures that no defective/loaded dice are taken into casinos or made for board games.
Casino Security Measures
Despite the various quality controls that are taken by manufacturers, some people can still create their own loaded dice. However, various casinos have their own security measures to help guarantee that loaded dice are not used at their tables. For example, in craps, players are not supposed to handle the dice with more than one hand, and the only way to change hands when throwing dice is to set the dice on the table, let go and then take them with the other hand. This reduces/eliminates the possibility of the shooter switching dice by sleight-of-hand.
Typically players are asked not to throw the dice higher than the eye level of the dealers, and there are various rules with how shooter can throw the dice in order to eliminate the possibility of people using loaded dice. In addition to this, the casino can switch dice from a table whenever they see fit in order to remove any suspected loaded dice, and to make sure that there are none on the table.
