none of the bets verify
If the server seed was changed at a particular nonce, the bets after that nonce should all verify using the latest server seed. If this set includes the losing streak, and unibtc was playing pretty unpredictably it's unlikely any foul play was involved.
I don't think there was any foul play involved, but here are some things that is a little suspcious:
1. The previous server seed is unknown. and so bets cannot be verified.
2. It is possible to change the seed to something that would statistically result in more losses to unibtc. Like rolls in the 48-52 range.
On the other hand, if PD had changed the server seed of hufflepuff/robinhood they wouldn't have lost a few hundred bitcoins.
