Distribution of hexadecimal characters in 100 transaction ID hashes. The important part is that the 7 occurred 7 of 100 times, or 7%, which is slightly higher than the game promise of 1/16 or 6.25%. That would explain why they are at a slight loss right now. The non-uniform range between 4 and 11 is interesting and suggests truly random results. If everything was between 6 and 8 I'd be a lot more suspicious. Edit: or 99 times, close enough.
