Just happened: In one game of triple dice poker i roll 34466. i reroll 344 and have 24466. I reroll 244 and get 34466 I enter and submit, going to the next game of the same type, and the dice are: 34466.

This is only a single case, but it is one example of many I have observed yet. More often than should happen by chance, the dice in a dice poker variant stay the same or almost the same when rerolled.

I only trust a PRNG when I have implemented it myself (but then not absolutely) or when it is based on a cryptographic method and checkable, as I have previously described here.
