There are now 4 free jigsaw puzzles ready for download. They differ from the purchaseable puzzles in that they do not have stick figures and starry backgrounds. The pieces are simply coloured differently. Their function is identical to that of the puzzles that need to be bought.
Try them out. If you don't like them - too bad. If you think they do help memorise the sky, well that is just great.
