What kind of research do you do to make these games? I'm positive that some of these "facts" - not many, but a handful - are either urban legends, or otherwise myths that people accept as facts without researching. And that's usually because they read it on some "random fact" page online, or from games such as this.
I love these games, but I can only rate 8/10 because not all the "facts" are factual, and the typos get really annoying, especially since the facts cycle through randomly and it's possible to keep seeing the same misspellings over and over again.
