All games are artificial problems, so your question actually is, what motivates people to engage in pastimes?

Sudoku, crosswords, Simon Tatham's puzzles etc. are an excellent way to pass the time while keep training the mind. Sports are their equivalent for the body.

Finally, writing solvers for a problem, be it real or artificial, for many is just another variety of puzzle to engage in.
