Why does my book have so many pages, or so few?

The count is the front pages, a title page per level, the maze pages (one or two mazes each), the "Solutions" page, the solution pages (1 to 6 each) and the thank-you page, made even. For example, the "Kids 4 to 6" starting point (60 mazes) makes 76 pages, and 100 adult mazes one a page with four solutions a page make 134 pages. Two mazes a page, more solutions per page or fewer front pages make the book shorter. KDP needs at least 24 pages, so give a short book enough mazes.
