I suspect that the dice in Dice Poker are broken: a couple of times I have observed that the re-rolled dice didn't change.
This is difficult to prove, however. Unfortunately the movelist only displays the numbers after the last roll. So one had to manually copy all re-rolls to do a statistical analysis.
