xjig

Finally I know how to work on with xjig, the jigsaw puzzle game! I've been browsing /usr/share/doc/xjig with no clue until I read posting about the manual. The guy mentioned he didn't get it, but I just do

$ man xjig

And, yes! I play xjig now! re's some of the key  resume (try on and see what happen):

Zooming: Home, End, Pageup and Pagedown

Moving: arrow keys

Mouse: left (rotate), middle (flip), right (move).

Good game!
