I don't understand that sentence. Why would his puzzle game collection waste anybody's time ? How come people know about it or even care ?
Nowhere there does he claim authorship, merely possession of a collection. Without knowledge of his webpage or the games, there is more than 1 logical conclusion.
My current timewaster is 'patterns',a nonogram puzzle
I assume that the interest in games and the hostname of his webserver are very much related.
If you can think of a non-card solitaire game, it's probably implemented.
