The dev calls the original boardgame “semi-obscure” and I feel like that might be understating it a bit. Mechanically, it's basically the more-sophisticated cousin of noughts and crosses, probably just as solvable, and presented in as simple a package as the old Microsoft games suite. Hell, when I won against the AI, the big squares bouncing around in the background came out Solitaire-style to squiggle all over the screen.
My progress: beat the AI at a full match
