Ooh, now here's something special! Six independent iPhone developers have joined together to offer seven word games for just 99¢ each! From speed-based spelling games to quirky word/picture combinations, there's no shortage of iPhone wordery to be had. The sale lasts through May 31, so get grabbin' while the grabbin's cheap.

Imangi - An imposingly large grid of letters fills the screen, with a few red bonus tiles dotting the landscape. Slide the rows and columns to create words vertically or horizontally, but the goal is to spell as many words as you can... simultaneously. Keep experimenting with letter positions to get the grid as green as possible. Sort of a combination of a sliding-based matching game, a word game, and a Rubik's cube. And yes, it might break your brain.

Moxie - A slow, strategic word game that challenges your vocabulary and creativity with letter placement. An empty 5x3 grid sits at the bottom of the screen, and at the top sits one letter taken from your queue. The object is to spell words using these letters, but to gain real points, you need to keep a chain of words going by replacing letters with new ones or adding on to existing words to make them longer. Moxie - Free Edition is also available.

Stitch'em Words - Similar to a rebus puzzle, Stitch'em Words challenges you to create words using both pictures (which represent words) and letters. After guessing what each image is, look at the empty spaces above to determine which words the game is looking for. Have a picture of a pea along with the letters C and E? You've got the word peace! It also bears a striking resemblance to the previously-reviewed Mac/Windows game PictoWords. A free Stitch'em Words Lite is also available.

Word Squares - Similar to Imangi above, Word Squares takes things to a smaller scale and tasks you with manipulating individual letters on a grid so the entire board spells words. Black letters can be moved as you please, but white letters are there to stay. No sliding here, just careful, head-scratching letter placement. A free Word Squares Lite is also available.

Also try out Wordology, an attractive tile-based spelling game, the previously-featured Textropolis, and Wurdle, a slick Boggle-type spelling game, all on sale just like the above games!
