The plugin is interesting, different from others with GUIs, which is why I chose it!
The problem are the illegal wins (e.g. with the blocks in “<” and “>” position, it doesn't make sense), the fact that every time you restart the server the board is removed, and you need to re set it, and the fact that you can't talk to the developer (I tried with the previous review, no answer. I tried on Discord, no response).

Nice and fun plugin! Is there a way to disable the "<" and ">" tris? I mean, make it that only vertical, horizontal and diagonal lines can win?

This is a fantastic plugin! no more of those boring GUI based ones. literally works as its meant to.
just 1 issue with the boards deleting on a server restart. the boards file also clears maybe im missing something? running 1.16.5
