From the developer:
It’s just a game. A really simple game. A really simple time-wasting curiously absorbing card game. I didn’t even make it up. Someone else made up the game; I downloaded it, it behaved in ways I didn’t like, so I wrote my own version, and this is it. The goal is simply to spot groups of three “cards” that are the same or different in all four of their “attributes”. No stopwatch, no scoring (I don’t like that sort of thing).
