A beautiful card game for iPhone and iPod touch.

I did all software development, graphic design, audio design, and marketing for Threeo and built it within approximately 9 months. This was my first time ever building a publicly-released software application on the App Store.

Teach myself iOS application development by moving rectangles around a screen in a delightful way.

I had come up with the idea for Threeo as a two-person card game the same time I was looking to teach myself software application development (and not just scripting).

Through many iterations while learning how to code, I refined the Threeo concept into a one-person card game that can be played in roughly 1–3 minute intervals.

Threeo launched for free on the App Store in 2013 with support for iPhone 4 and iPhone 5 devices and was within days one of the top-downloaded new card games with hundreds of downloads.
