Roll Dice

What is a Dice?

A dice is typically a small, throwable object that has multiple faces (most commonly six) and possible positions that indicate a number (or something else), used for generating random numbers and events. They are typically used for tabletop games, which include a wide variety of games, as well as for gambling. Examples of tabletop games that involve the use of dice include games like backgammon, Boggle, and Yahtzee, where dice are a central component of the game. Some other well-known tabletop games include Monopoly, Risk, Dungeons and Dragons, and Settlers of Catan. There are however, numerous others.

The most commonly used dice shapes are:

• Tetrahedron: 4 faces - the blue dice.
• Cube: 6 faces - the orange, cubic dice.
• Octahedron: 8 faces - the green dice.
• Pentagonal trapezohedron: 10 faces - the orange, non-cubic dice.
• Dodecahedron: 12 faces - the yellow dice.
• Icosahedron: 20 faces - the purple dice.

Above are common dice shapes, there are many other polyhedral dice, or dice of other shapes. There are also non-numeric dice, dice that do not follow a counting sequence that begins at one, and spherical dice.

How random is a dice?

Based on probability, a dice should have an equal probability of landing on each of its faces. However, this is not necessarily the case with mass produced dice as they cannot be truly random, since it is difficult to mass produce dice that are uniform, and there may be differences in the symmetry of the dice. Each dice, particularly d20 (20-sided polyhedral dice) and d8 (8-sided polyhedral dice) is often unbalanced, and more likely to roll certain numbers.

For a well-balanced dice, you can expect a variety of numbers. If it is not well balanced, you will be more likely to notice certain numbers occurring more often. However, unless this test is performed numerous times, or the dice is heavily unbalanced, the user is not likely to notice a significant difference.

There are a number of companies that manufacture dice, and some more rigorous tests (than the one described above) have been performed on dice manufactured by different companies in an effort to determine how truly random the dice (mostly d20 dice) are. These studies confirmed that even dice manufactured within the same company under the same conditions could vary significantly from each other, and are not truly random. Some companies produced dice that were more random than others, but even then, they were not found to be truly random.

How we guarantee randomness

Our virtual Roll Dice is truly random. To ensure genuinely unpredictable results, this site does not use the standard Math.random() function. Instead, the wheel's physics are driven by the crypto.getRandomValues() function, a specialized, high-security API standard built into modern web browsers. It draws from your operating system's cryptographically secure random number generator (CSPRNG), which is designed to be unpredictable. This secure random number isn't just used to pick a winner from a list. It's used within the physics simulation of the wheel, ensuring the outcome is genuinely random and impossible to predict.
