Are the resin dice balanced?

What are resin dice?

Resin dice are formed by hand or machine by pouring materials such as epoxy resin and acrylic resin into specific resin dice molds. Compared with common plastic dice, resin dice tend to have higher transparency and more complex decorative features. During the production process, glitter powder, metal flakes, gradient colors, patterns, quicksand and other elements are often added to increase their visual appeal. Therefore, resin dice have become a favorite of many tabletop game players and collectors due to their unique aesthetic value and personalized design.

What is the balance of resin dice?

The balance of dice means that the probability of each side being thrown out each time is the same, and it will not be biased towards a specific side or number, that is, the center of gravity of the dice should be at the center of the dice.

Although rolling dice is a matter of luck, the balance of the dice is also a concern that cannot be ignored, especially when the dice directly affects the fairness of the game. Although resin dice are beautiful, do they always provide a completely fair dice-rolling experience? Is it possible that they are unbalanced due to problems with the manufacturing process or decorative design? This article will reveal how to evaluate the balance of resin dice to ensure that every dice roll is truly fair.

Factors Affecting the Balance of Resin Dice

  • Uneven resin mixing
The resin may not be fully mixed during the production process, causing some parts to be heavier than others, which in turn affects the center of gravity of the dice.
  • Distribution of decorations
The core of the liquid core resin dice will be filled with liquid, mica powder, metal flakes, glitter, color particles, quicksand and other decorations. The uneven distribution of decorations will also cause uneven mass of the dice, which will affect its balance.
  • Bubbles and defects
Bubbles may be generated during the resin curing process. These bubbles will cause uneven density inside the dice, which will affect its balance.
  • Mold precision

If the mold is not made accurately, it may cause the shape of the dice to be irregular, which will affect its balance. Molds with lower precision may cause one side of the dice to be heavier or lighter, which will affect the result of its roll.

How to check whether the resin dice is balanced?

1. Visual inspection method

The simplest evaluation method is to check the appearance of the dice with our eyes, check whether the dice has a regular shape, whether the surface is smooth, whether there are obvious bubbles or uneven color blocks. It is also important whether the decorations (such as metal pieces, glitter powder) are evenly distributed. Observing these details can help you make a preliminary judgment on the balance of the dice.

2. Multiple throw verification method

Through multiple dice throwing experiments, you can observe whether the randomness of the resin dice is sufficient. In the test, you need to use the same throwing method to throw repeatedly 100 times or more, and record each throw on paper, and then check whether the frequency of each side appears is roughly the same. If one side appears frequently, it may be because the center of gravity of the dice is offset, causing it to always lean towards the same side when it lands.
Tip: The deviation of the throwing test requires thousands of throwing attempts.

3. Salt water test

Salt water test is a simple and interesting way to test balance, which is more effective for testing the internal weight imbalance of dice.

Step 1: Prepare a transparent container, inject an appropriate amount of clean water, and then slowly add 2-3 spoons of salt and stir evenly until a saturated salt water solution is formed. Generally, the larger the container, the more clean water is added, and the more salt needs to be added.

Step 2: Gently place the resin dice in the salt water and observe its performance carefully. If the dice can remain relatively still in the salt water without obvious tilt or bias to one side, it means that its density distribution is relatively uniform and the balance is good. On the contrary, if the dice has obvious floating difference, one side continues to face up or there is unstable shaking, then it is likely that there is a slight imbalance in its internal structure or material distribution.


Step 3: Flip the dice by hand, and pay attention to the movement trajectory of the dice during the flipping process. The movement of a well-balanced resin dice should be relatively natural and random. It will roll in the direction of the water flow, with both sides facing up and down alternately, without obvious deviation.

Step 4: After gently stirring the salt water several times to make the dice flip, let the dice rest again. Observe how often each side faces up when the dice finally comes to rest. Ideally, after enough flips, each side should face up roughly the same number of times. If you find that one side faces up significantly more often than the others, this means that the dice may be unbalanced in density or shape, causing this side to be more likely to face up under the action of buoyancy and gravity.

How to choose a balanced resin dice?

1.Check before buying

Before buying a resin dice, try to check its appearance and center of gravity, understand its manufacturing process and materials, and ensure that it meets quality requirements. You can also refer to the merchant's product description and evaluation when purchasing.

2.Brand and quality control

Choose a well-known brand or a reputable manufacturer, which usually provides high-quality resin dice and undergoes strict quality control to ensure the balance of the dice.

3.Purpose of use

Choose the right dice according to your usage needs. If you are mainly using it for competition, it is recommended to choose highly balanced dice that have undergone strict quality control; if it is just for casual games, decoration or collection, the balance may not be too demanding.
