I just picked the last one to verify.

Again the only wins are where skipping one win takes him to another winning number - it seems the code never skips two rolls in a row, but also never skips a loss:



Edit:

http://privatepaste.com/80a5e48d6c has a list of the rolled numbers for nonces 4800 through 5200 if you want to check any of the other screenshots for skipped rolls. Or you can generate your own using rgbkey's verifier (which verifies one roll at a time):

or my modified version of it (which verifies a range of rolls):
