I have not released the 2024 version yet. This is an old version

One interesting thing is that first player losses on 4x15 but wins on 4x16

This is one of the many reasons why I love the swap rule so much.

SigmoidHzy, are you claiming that these board sizes have been solved?
I don't think so. What is your proof?
I think these resuts are emperical.

Almost impossible to actually solve them. But these results are very likely to be true. Most of them with a winrate of >95%

But 7x7 and lower has been 100% solved already, this is why it isn't an arena mode.
