Sorry about the clickbait title (: It's still a usable go board it's just an unconventional size. My latest build video and dispite the mistake I'm pretty happy with how it turned out. Enjoy!
Thanks for sharing your work @AndrewJones.
More tiles for more fun?
Yep, will make a longer game. The standard go board size is 19x19, a 15x15 go board makes a shorter game. So 16x16 is in the middle.
