As a weekend project I built this simple game. It become a funny project to play.
PS. Be careful, do not "try" to make sets, find by your eyes.
Not color blind friendly. I mean not everything must be usable with full color blindness, but even a small game would be nice to be usable with slight color blindness. The green/pink, relatively thin borders are indistinguishable.
Oops, I didn't think about it. I'm going to fix this as soon as possible!
