From Lucas Learning:
Pit Droids is a challenging, fast-paced Star Wars: Episode I puzzle game. The surly junk trader Watto beckons players to confront over 300 puzzles featuring endless rows of pit droids in six realistic environments on Tatooine, including Watto's shop, the open desert, a Podracer hangar, and the interior of a transport ship. The relentless droids come in a variety of colors and models, and march under their own power. Without the player's guidance, they march straight off the edge of the world. By directing them towards appropriate goals, players advance from location to location, working their way to the Podrace Arena at Mos Espa.
Players can compete for a high score, play random puzzles one at a time, or get a guided tour from C-3PO. Puzzle Maker is a powerful tool that allows players to create their own puzzles--and send them as an email attachment--to challenge their friends.
