Type any seed word or number — or press the dice to get a random one — set the range and count, then press Generate. Share the seed so others can reproduce the exact draw.
The seed sets the starting state of the pseudo-random algorithm. From the same starting state the algorithm walks the same path every time, so the same seed reliably produces the same sequence of numbers.
So a draw can be audited. Publish the seed before a giveaway, or note it in a simulation, and anyone can rerun the tool and confirm they get identical results — something a normal random generator cannot offer.
No. It uses the mulberry32 pseudo-random algorithm, which is fast and evenly distributed but predictable once the seed is known. Use it for fairness and reproducibility, never for passwords or keys.
