I'm either at the end of Returner77 (Part 1) or the beginning of Returner77 (Part 2). It is a beautiful and entertaining game and simple enough that I have completed it it, thus far, without help. HOWEVER; there is now a fairly common puzzle which has been my nemesis since forever. It consists of three blue things in a row on the left side; an empty space in the center; and three red things lined up on the right. The object is to move all the reds to the left and the blues to the right, but I can only move, or jump, one space at a time. It's an old puzzle that I've seen a dozen times and can never complete. Ant idea where on the web there's a picture. I'd look myself, of course, but I have no idea what to call it.. Any help would make me a happy old curmudgeon.
