@puniko I'm a bit confused
Can I use the checker midway to make sure I'm right? Or does it have to be at the end?
I did this and now I'm stuck... and checker says it's wrong but idk if it means I'm wrong or if it's just too early to use it... (also I don't see a small clue in the top left corner so idk what the killer rule means)
Is there a tutorial somewhere? :neofox_confused:
EDIT1: looking back at the screenshot, I see the 12 at the top left of the right cell
So I guess that's the killer thing...
