Super Mario's 30th anniversary took place on the 13th of this month (2015) to honor the anniversary, Google planted a ? Block right beside the Super Mario Bros game description in their search results. just search "Super Mario Bros" and at the far right of the search results you can click the ? Block and eventually even gain over 100 coins and a free 1 up. I know this news is a tad old but news is slow today 9/16/2015 and this is kind of neat of Google to have done this in honor of this game's history and how it has impacted our culture.
