Fair draws · LESSON 1
The 6 fairness principles — what is fair
These are the 6 principles any draw must keep to be fair. Break even one and it is not fair.
1
Even
Give everyone the same win probability.
2
Commit ahead
Seal and disclose the method and list before the draw.
3
Unpredictable
With safe random, nobody can guess the result.
4
Unchangeable
Once sealed, no one can change the result.
5
Verifiable
Anyone can recompute and verify the result.
6
All recorded
Every step is kept, viewable again later.
