Random Number

What is Random Number?

A random number is a number chosen from a pool of limited or unlimited numbers that has no discernible pattern for prediction. The pool of numbers is almost always independent from each other. However, the pool of numbers may follow a specific distribution. For example, the height of the students in a school tends to follow a normal distribution around the median height. If the height of a student is picked at random, the picked number has a higher chance to be closer to the median height than being classified as very tall or very short. The random number generators above assume that the numbers generated are independent of each other, and will be evenly spread across the whole range of possible values.

A random number generator, like the ones above, is a device that can generate one or many random numbers within a defined scope. Random number generators can be hardware based or pseudo-random number generators. Hardware based random-number generators can involve the use of a dice, a coin for flipping, or many other devices.

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.
