Why puzzles


	We may express following views:

		1.    Arcade games do use and train "finger muscles" and "eye muscles" ...
		10.   "Find an object" build "eye muscles" and little "brain muscles" ...
		1000. Puzzles do "brain muscles" ...
		
	Numbers on the left: usefullness for cognition and mental creativness.

	Of course, not all puzzles are born equal.
	For example, one can sort Sokoban-clone puzzles by "creativity index".
