I'm always on the lookout for applications to keep me entertained when I have little snatches of time that need filling: Waiting in a long line at the post office or for a movie to start, or being caught out at lunch without a book to read while eating.

Word Flow is an interesting puzzle game that allows you to slide letters around a board to create words. Once your word is ready, tap the beginning and last letter of the word you've created. It's like Boggle with the ability to control where letters go. You have three timed versions you can play: One minute, three minutes and 10 minutes. Three minutes is the sweet spot for me. With the one minute version, you barely have time to string some words together before time is up. With the 10-minute version, I lost interest after about five minutes.

Overall, Word Flow is a fairly decent game, but definitely not my favorite of available word games on the iPhone. The graphic response is not as smooth as other programs, and two versions of the game are either too short or too long.

Word Flow (link opens iTunes) is currently available for $.99USD.
