Questions & Answers

Is this online dice roller truly random?

Yes. Our tool relies on robust pseudorandom number generators built into modern web browsers, ensuring a fair distribution that matches the behavior of physical dice precisely — with no hidden weights or biased outcomes.

Can I roll multiple dice at once (like 4d6)?

Absolutely. Simply change the 'Number of Dice' field to whatever quantity you require. The simulator will cast all of them simultaneously and automatically calculate the sum total for your convenience.

What does the 'Modifier' field do?

In RPGs, you often need to attach a flat bonus or penalty to your roll (like 1d20 + 4). By adding a value to the Modifier field, the engine automatically considers this math operation in the final 'Total' output.
