One big advantage of the three tests I described is that I usually get very good binary outcome—yes or no. It’s not so with most other computer games, or other tests I tried. And they’re all quite pleasant activities—even if I wouldn’t necessarily want to spend an entire evening playing Quake 3 or doing go problems, I’m usually quite happy to spend 10 minutes on them.
