What do you get when you combine a popular service spouting interesting/funny/out-of-the-ordinary  factoids on Twitter, and an iOS word puzzle game in which players have to guess the word/phrase/name based on the given clue? A win-win situation. The folks at Playscreen LLC, the creators behind the hit word puzzle game Crickler 2 have teamed up with Uberfacts to feature the latter’s content in the game.

Uberfacts was started by Kris Sanchez back in 2009 and has gained quite a following on Twitter (3 million and counting), while Crickler 2 has hit #1 for both Free Puzzle Game and Free Educational Game categories on the App Store. With Uberfacts’ factoids powering the game, players can find more than 30 such puzzles in-game, with more being added to it daily.

Remember when I said this is a win-win situation for both parties? Here’s how they do it: The UberFacts agreement illustrates how Crickler serves as an innovative channel for those interested in being featured in a top-rated iPhone app. Case in point: PlayScreen has already started to run special contests that reward players who have solved UberFacts-powered puzzles with $50 iTunes gift cards. To win, players need to share their achievements on Twitter and follow UberFacts’ account – “closing the loop” and ensuring a high level of user engagement for all parties.

“UberFacts provides some of the most amazing content out there, leading to some impressive Crickler puzzles. Trivia aficionados will find these puzzles challenging and totally addictive,” says William Volk, CCO, PlayScreen. “More so, this deal opens the door to a future where TV shows rely on Crickler to deepen the connection with their audience—and where charities use Crickler puzzles to raise awareness around important social and health issues. The possibilities are endless.”

Crickler 2: Daily Word Puzzle can be downloaded for free from the App Store. Players start with 30 credits, which are used every time a new puzzle is chosen. More credits can be purchased in-game—or earned by watching Tapjoy ads or bragging about their Crickler victories on Twitter and Facebook.
