Watching these videos, I’m going to think twice before resigning. Great content.

Thank you 🙏

Great video mang! I setup a few of these on my board at home and it was really fun to sit and try to solve.

[@BalkanDadChess]

They’re so mind bending, I’m glad you attempted them it makes it so much more interesting when attempting to solve it first. Thank you as always 🙏

Wasn't the last game from anime Classroon of The Elite Season 3? Or maybe they just copied it...

[@BalkanDadChess]

I have no idea what that is

[@demtyyy4213]

Oh, then ok
