Columbia, SC (WLTX) -- If you're familiar with the games you can play on Facebook - you already know Derry's App of the day - it's just as addicting on your mobile device too.

In 2008 the company PopCap Games introduced Bejeweled Blitz on Facebook - and immediately millions of people were addicted to playing the game. Productivity dropped. Sales of headache meds went through the roof. And it was all thanks to playing this puzzle game.

If you've played online, you know just how much fun this one is. Your goal is to match as many gems in line as you can, in the one minute time limit. You can compete against your friends for the highest score, you'll be sucked in really fast.

When you're playing this app, you can play off-line or online, and there are different items you can use to boost your scores. In the online version you can use three of those at the same time to get higher scores, and they'll refill over a period of time.

What's the point of this one?

Well believe it or not research has been done around this game. One Massachusetts university did a study and adults over 50 playing this game reported felling sharper mentally. The psychology researcher said Bejeweled Blitz is a plausible platform for improving cognitive skills in adults.

So if you play this game, you'll build your mental skills and speed.
