Fair draws

Results are drawn by the system at random. Nobody enters or edits them, and you can check that yourself:

1. When a round opens, the system creates a secret random seed and shows its SHA-256 hash straight away. The hash pins the seed down without revealing it.
2. At draw time the result is worked out from that seed alone: HMAC-SHA256 of “game:round” keyed with the seed, first 13 hex digits as a number, then the remainder after dividing by 100 (2D) or 10 (Colour). In 2D the first ball is the tens digit and the second ball the ones digit.
3. After the draw the seed is published below. If it hashes to the value shown before the draw and gives the same result, the outcome was fixed before any bet was placed.
