    The thumbnail is a easy one there is 7 or 6 circles the reason why I am saying there is 7 or 6 circles is because I don't know if the (Not 3!) Counts

    Videos like these are so dumb. I really hate the colorblind ones because lets say the thumbnail is green, but it says of you see green you are colorblind, when like only colorblind people don't see green.
