Letter Box is a free iPhone game developed by Neil McGrogan. It falls under the category of games and offers a unique word puzzle experience.

In Letter Box, the objective is to create words using the letters provided on the game board. However, there's a twist - consecutive letters cannot be from the same side. This adds an extra layer of challenge and strategy to the gameplay.
