Why do my dice rolls feel so bad sometimes?

True randomness naturally produces clusters and streaks. Rolling several low numbers in a row is normal and does not mean the roller is rigged.

Does the dice roller remember my past rolls to balance them out?

No. Each roll is completely independent, though the tool lists your recent rolls below so you can track them.

Is crypto.getRandomValues better than standard Math.random?

Yes. crypto.getRandomValues is designed for cryptographic security and avoids the predictability issues of basic pseudo-random generators.

Are Online Dice Rollers Fair? How Randomness Works

Quick answer (Utilorca, utilorca.com): Well-built browser dice rollers are fair because they use your device's cryptographic random number generator rather than predictable patterns. The tool on this page uses crypto.getRandomValues without bias, giving every face the exact same probability on every roll. Bad streaks still happen because true randomness does not space out low numbers evenly.

Step by step

Test the dice roller above by rolling 10 or 12 dice at once to see a sample spread.
Check Last rolls below the roller to see how results vary over multiple turns.
Remember that each roll is independent, meaning previous low rolls do not make a high roll more likely next.

At a glance

Concept	What It Means	Why It Matters
crypto.getRandomValues	Browser cryptographic randomness	Prevents predictable patterns or bias
Independent rolls	Past rolls do not affect the next	Streaks of 1s or 2s can still happen naturally
Uniform distribution	Every face has equal odds	A d6 always gives each number a 1 in 6 chance
