You can tell what it is from the title. Super Mario is a popular video game character and has been for over 30 years. This is clearly a video game. Good job on being facetious though.
I just replied to one of your other comments where I argued that the title was enough to tell you everything you need to know. But I guess I can see how other people wouldn't see it that way.
For me, the fact that it is a game named Super Mario Run, made by Nintendo, for the iphone, instantly tells me that it will be a side scrolling runner-style game featuring Mario in Super Mario Bros style levels, with basic touch controls. In fact it occurred to me that I hadn't verified these assumptions and I just checked out the about page and found that it looks exactly like I expected.
I guess some people make the exact same assumptions I do, and this is totally not obvious to others, hence all of the miscommunication and arguing in this thread.
I replied to your other comment, and my stance is unchanged.
You got lucky in assuming what the game would be about. If you had done the same thing with other games (e.g. Pokemon Go) you would have completely missed the opportunity to discover a new kind of game.
I advise not judging things by their cover, unless you want to risk not discovering something new.
