1) If you are a newbie to this game, or you do not do jigsaw puzzles much, start out on the easy level, just to get used to where things are. However, as soon as you get good at it, go to the hard level. The most I ever got on easy was around 300 points. There is an upper limit of 1000 points on hard, and I go over that every time I play.
2) For hard level 1, the pieces are set up really well. The puzzle is a rectangle, with 5 columns of 3 pieces each. Going from right to left, each of the columns are right where they should be, just the rows are wrong, and all you have to do is fix them. Almost no moving around of any piece you don’t want to place is needed.
