Important
Check the result before relying on it
Review generated output before using it in production. Formatters and converters can validate structure, but they cannot understand every application-specific rule or guarantee that transformed content has the intended meaning.

Questions
About this tool
Is this suitable for regulated drawings?
No. It uses strong browser randomness, but Lucaden is not a certified lottery, gambling, audit, or regulated draw platform.
How are integers sampled?
The tool uses rejection sampling over browser cryptographic random bytes to avoid modulo bias.
Open-source foundations
