Think Tetris, but upside-down, with letters. That's the best way I can think to describe KERN (App Store), a new game for the iPhone. From the site:

KERN is a minimalist typography experience challenging you to precisely place a missing letter into a falling word while avoiding any unnecessary ligatures!  Practice and prove your typographical acumen with a score that gives new meaning to point-size!

The design is beautifully minimal and well thought out. It's also easy to pick up and well worth the $0.99, even if your not into typography. I think this might be my new go-to game.

Video of the game play available after the break.
