What does unique mode do?

It ensures no number repeats in the results. The count can't exceed the size of the range.

How random are the numbers?

The generator uses your browser's built-in randomness source, which is suitable for everyday uses like giveaways, games, and test data — not intended for cryptographic security purposes.

Can I generate negative numbers?

Yes — set your minimum value below zero and the generator will include negative numbers within your specified range.

What happens if I ask for more unique numbers than the range allows?

It's mathematically impossible to generate more unique values than exist in the range, so the tool will flag this rather than produce duplicate values in unique mode.

Can I use this to simulate dice rolls?

Yes — set the range to match your dice (1 to 6 for a standard die, for example) and generate as many rolls as you need at once.

How many numbers can I generate in one go?

Up to 1000 numbers per generation, which comfortably covers most practical use cases from a single random pick to a large batch of test values.
