OK, fellow Boomers. I'm in the "Yellow Swimming Pool". I've been trying to aim the white ball into the chute, but without success so far. I know I have to move the "blocks" into the correct positions in order to deflect the ball to go into the chute, but so far, it's a no go. I just have to keep on trying. The WT shows a pic of the proper positions of the blocks, but I haven't gotten it right yet. I HAVE completed the puzzles in the other two rooms so far.
