賭 Once again I've found a kanji that is "written" in different way in the book and the normal typeface here. If I look it up it's supposed to have 15 strokes, which means that little drop shouldn't be there. I guess it's an issue of printing fonts vs. handwriting but does anyone really know what's right or wrong here?

On my computer (a Mac), if I copy-paste your kanji 賭 in a text editor, I see the font "Hiragino Kaku Pro N" and I think the N is important here because it could mean it's a chinese variant of your kanji. If I change the font to "Hiragino Kaku Pro", the drop disappears.

賭, like 箸, is outside the Joyo kanji (until next year). See this post.

Edit:
@mypapa12: The "N" font is a Newer version of the font, but still Japanese.
