Randomness from a physical source
Each drawing seeds its generator with randomness from the NIST Randomness Beacon, a public feed produced by quantum-physical processes, mixed with fresh entropy from the server. The source is printed on every result page.
Every entry counts the same
Winners are selected in a single pass with an algorithm that gives each entry the same chance, then shuffled before places are assigned, so a row near the top of your file is no more likely to take first place than one at the bottom.
Signed, checkable records
Each completed drawing is published with a digital signature covering the winners, the timing, and a fingerprint of your file. Anyone can confirm on the verification page that a record is genuine and unaltered.
The source list stays attached
The file the winners came from is published together with the result, so people can see the pool that was drawn from and not just the names that came out of it.
Everyday random generators
For the times a random result is just a random result. These run in your browser, so nothing you type reaches us and nothing is kept.
