I am currently researching on Recreational Mathematics - Mathematical Tricks and I have come across this article: Ten Amazing Mathematical Tricks .

This article is of free style and does not follows the pattern/format I have seen in all the other articles/research paper so far.

My question is: Is this a research paper? Is it a paper? If not, what is it? Can such a paper be cited as a reference? I want to know more about these freestyle articles.

I can't see the actual article, but if it's an MAA article by Martin Gardner, it's probably a list of interesting puzzles. Peter Winkler also writes a column of this kind.

These might not be "research papers" in the sense of proving new theorems on a topic, but they're interesting communications. You can of course cite such a paper as a reference if you use some material from it (and you should!)
