What should you confirm before using a randomized result?
Microlearning guide
Random does not mean balanced
Small samples can look uneven. Fair random processes still produce streaks, clusters, and repeated-looking patterns.
Define replacement
Removing winners creates sampling without replacement; keeping entries allows the same option to appear again later.
Use the right tool for stakes
These browser tools are for everyday selection and games, not audited lotteries, legal draws, or security-critical randomness.

Frequently asked questions
What does 2d6 mean?
It means roll two six-sided dice and add their results.
How does the modifier work?
The modifier is added to the sum after all dice are rolled. It can be positive, zero, or negative.
Can I roll a d20?
Yes. d20 is included along with d4, d6, d8, d10, d12, and d100.
What randomness source is used?
The roller prefers browser crypto randomness when available and otherwise uses Math.random for ordinary game use.
Is this a physics simulation of real dice?
No. It is a digital random-number model for standard dice faces, not a physical motion simulation.
