House edge does not factor on PD. If for instance, you chance of loosing is 1/10000, then on PD you will lose within 1000 bets ALWAYS. Then, it will be revealed that the bet you lost on -YOU actually won -BUT Primedice's developer cannot obtain the bet ID's to PROVE anything. BEWARE of PD... this is what happened to Lain33 of PD2, who gambled loads until PD screwed me.
