I asked for Eights to be added, saying it was like Six by Six but with two packs and laid out 8 by 8. I have just tried it. I find the deal puts all the aces straight onto the foundations. The deal ought to leave the aces where they were, as digging for them is half the challenge. If that is what Six by Six does then the mistake is mine, my apologies. Othewise, it seems to work.
Apologies for the long reaction time. I could not get PySolFC to run on my Mac, and forgot about it. That problem is solved in v3.6.1.
