Wordsmith is a game similar to Bookworm. In fact it started out as a test to see if I could create a Bookworm-like game. The result is something a little different. Featuring a dictionary of 200,000 words, you can create words in a variety of ways and rack up bonuses with special tiles. You can also control the direction of the falling tiles.
This is perhaps one of my better games along with Whippy.
