The very first official release of Adobe Photoshop was in February of 1990. This year is the 25th anniversary of our favorite photo manipulation suite and Adobe is celebrating with a classic party game.

Real or Photoshopped is a landing page recently set up on Adobe’s website. This online webapp runs like a typical game where you go round-after-round guessing the legitimacy of individual photographs.

Some of them are just blatantly obvious, but others definitely threw me for a loop. It’s a fun little game and also an interesting way to recognize the cultural significance of Photoshop since first hitting shelves in the early 90s.

The game is obviously free and it’s a fun way to improve your keen sense of ‘shoops.

If you have some free time why not take a swing and play a coule rounds? If you’re really into it be sure to share this on Twitter and all your favorite social networks – and give Adobe some thanks, too!
