Bill Darrah

Bill Darrah is a professional designer of puzzles who is best known in the CC community for designing approximately 1/3 of the original Chip's Challenge levels, as well as 7 levels that were included in Chip's Challenge 2.

Bill's level design style is often distinctly recognizable for its homogeneity, mathematical precision, and emphasis on sprawling mazes. His levels in many cases are known for being equal parts beautiful, tedious, and difficult (for example Doublemaze, Rink, and Force Field).

Trivia

Bill has an online shop called Yorkhouse Puzzles and Surprises where he designs and sells mechanical puzzles. The logo bears an obvious resemblance to the castles in the [CC1] levels Yorkhouse and Castle Moat.

According to Joshua Bone, there is a word-of-mouth story from Chuck Sommerville about the level Castle Moat. Bill Darrah reportedly designed the level, and then Chuck inserted the now-famous flippers without telling him.
