What I don't do
Crossword puzzles, jigsaw puzzles, trivia games, action games. I do design multi-player games, but single-player puzzles are my specialty.

What I can do for you

• Design puzzles for your console or computer game.
• Consult on improving puzzles, or recommending puzzle directions for your project.
• Write monthy puzzles for your magazine, tuned to the interests of your readers.
• Build weekly puzzles for your web site that will help you attract repeat customers.
• Tailor puzzles to your marketing or ad campaign that deliver your message in an entertaining way.
• Create teaching games for education or corporate training.

How I work
I start by understanding your business goals and practical concerns. Who is your audience? What result should your game accomplish? What are your budget and technical constraints?
     I then produce mockups of several possible games. Once we have chosen a direction, I write a detailed game design document specifying how the game is to be built. I can work either with your in-house production staff, or provide complete production services through my network of associates. Sometimes I build games from scratch; often it is easier and less expensive to customize one of my existing games.
     Throughout the production process I work closely with programmers and artists to monitor progress and resolve questions. I participate in testing sessions. For web games, I participate in ongoing fine-tuning and maintenance.

My background
My background includes work in graphic design, user interface design, programming and mathematics education. My colleagues include leading puzzle designers around the world, computer puzzle game designers, and mathematics educators. I talk frequently at game design and mathematics education conferences. I have written two books: Inversions, and The NewMedia Puzzle Workout. I have a BA in music and a PhD in Computers and Graphic Design from Stanford University.
