To create custom dice for your tabletop game using the making dice technique, you will need to design a mold for the dice shape, pour a liquid material like resin or silicone into the mold, and let it set and harden. Once the dice are fully cured, you can remove them from the mold and customize them further with colors, numbers, or symbols.
The answer depends on what you are rolling: three or more ordinary dice, or fewer dice with non-standard numbers on them, or a die with some other shape.
