A simple but addictive time-wasting card game involving perception. Great for training the brain, staying sharp. The idea is to spot groups of three cards that are the same or different in each of four attributes. I didn't invent this game; I just wanted a nice version that I could play on my computer, and this is it.
What's new in this version:
Revised for Leopard (Mac OS X 10.5) and Snow Leopard (Mac OS X 10.6); universal binary, including 64-bit. [The earlier PPC-only version, compatible with earlier systems and including source code, is still available.] Thorough code revision, many miscellaneous bug fixes. Much nicer "card" display. Animated card replacement. Help documentation now included.
