Inch Worm on Mac.

Inch Worm is now available on Macs. Thanks to Apple's Catalyst library, only a few minor changes were needed to port it from the iPad/iPhone to Mac.

Kids develop problem-solving skills by facing challenges, getting stuck, struggling a bit, then finding the solution. A little giggling always helps.

Rings 1.1

We’ve just released Rings 1.1. The graphics are now PDFs, which are both smaller and crisper, especially on larger devices.

Rings is an addictive collection of 32 puzzles that will challenge your skills in problem solving sequencing, and pattern matching. It looks easy. Just slide the rings to the matching positions. It gets hard. Here’s level 2. Can you figure it out?

Inch Worm 4.2

I've just released Inch Worm 4.2. It looks great on the new iPhones, without any tweaking.

Inch Worm is a collection of strategy puzzles for kids. They lead Inch home, past various characters including cherries, acorns, snails, ladybugs, and dragonflies. The characters are introduced gradually, and each provides a new challenge. Inch Worm provides plenty of fun, along with tons of practice in planning, problem solving, logic and spatial relationships.

Happy 2nd Anniversary!

It’s been exactly two years since Inch Worm 1.0 hit the app store. Since then the quality and sophistication has improved, and the White Pixels collection has grown to four puzzle games.

Building the Audience

My satisfaction comes from kids playing these games and deepening their critical thinking skills. I’m spending some time this fall trying to build the audience.

These apps have a surprising international market, with downloads from 30+ different countries. All four apps occasionally break into the top 100, and even the top 10 in several categories (Kids 9-11, Educational Games, Family Games, and Puzzle Games) – in the Czech Republic, thanks to Mensa ČR. It’s a lot tougher in the bigger markets, where I’m still waiting for my big break.

Ways to Help

App Store star ratings and reviews are essential. If you and your kids have enjoyed these games, head back to the App Store and let others know. You can also help spread the word on social media. Thanks for your help!

Inch Worm in the Czech Republic

I've been puzzled by several Inch Worm sales in the Czech Republic. Then I discovered this site:

The iTunes App Store description of Pegs is now available in Spanish. This makes lots of sense, since there are no words in Pegs. I'd love to help everyone discover it!

As you can see, Inch has grown a bit older and a lot cuter. You can now solve all 72 puzzles in any order. I’ve also fixed a couple of gnarly bugs.

Make Problem Solving Fun

Inch Worm by White Pixels is an addictive collection of maze puzzles for ages 6 to adult. Students lead Inch home, interacting along the way with cherries (eat them), acorns (push them out of the way), leaves (make bridges), snails (push them home), ladybugs (push and pull them), and dragonflies (herd them home). 

Success requires skills in planning, problem solving, logic and spacial relationships. Some students will plan Inch’s entire route. Others will look for the next step that does no harm. Appropriate subgoals help kids solve the advanced puzzles. Their solutions reveal differing thought processes. Everyone will make some mistakes, and learn from them! It’s all good.

App Name:  Inch Worm by White Pixels

Platforms:  iPad, iPhone, iPod touch, $0.99, no ads, no in-app purchases

Who knew?

Who knew what it would take to get a simple game for kids released in the App Store? Engineering - my speciality - was just a small fraction of the work. But we’re getting close…

Inch Worm is scheduled for release on September 6th. Whew!

Playing and Learning

"Play is a big part of how kids learn."

"For kids, especially kids under the age of 12, playing is learning and learning is playing.… So when we think about playing and we think about learning, the distinction between the two is very blurry and I think that as an organization, as an industry, we need to be a little bit more aware of that…

Favorite Kids' Books

In designing educational games for kids, some of my inspiration comes from children’s books. Here’s four of my all-time favorites:

by Sandra Boynton
The Very Hungry Caterpillar
by Eric Carle
Mouse Paint
by Ellen Stoll Walsh
Make Way For Ducklings
by Robert McCloskey

I’ll never match this level of quality or appeal, but it’s nice to at least know where I’m aiming.

What are your favorites?

Aplia Values


It's been a couple of years since I retired from Aplia. Before I forget, here's some of the values that helped make Aplia a great place to work.

Hire people that are smart and nice.
    They can learn everything else.

Get to know your users.
    Figure out what would make life better for them.

Design the best product for students and instructors.
    Everything else (sales, profits, ..) will follow.

Keep the design simple.
    White pixels are free!

Build a little. Test it with users.
    Then build some more. Then test it again.

Measure it. Fix it.
    Then measure again to see if you fixed it.

Give bugs top priority.
    Don’t build more if you have bugs.

Avoid add options for this and that.
    Add an option, go to jail.

GigaOM Infographic

A beautiful infographic prepared by GigaOM outlines the size of the iPhone App economy. Go check it out. We'll wait.

iPhone Apps

$250 million revenue in December 2009
$175 million (70%) goes to developers
$75 million (30%) goes to Apple

iPhone Sales

Apple sold 8.7 million iPhones in Q4 2009 (not counting Touch)
Guessing $150 / phone, that's $1.3 billion, plus carrier subsidies

iPhone Contracts

Users spend an average of $4.37 per month on apps
Users spend (my guess) $80 per month on connectivity


App Development is Big.
iPhone sales are Bigger.
Data plans are Biggest.
