Archimedes game.
The most difficult and probably the most interesting puzzle, the so-called Archimedes game. It can be made of thick cardboard, cardboard or plastic plate. The rectangle should be divided and cut into 14 different parts. The sides of the rectangle should be in relation 1:2. From the obtained elements, you can do this, as in the first given puzzle, make all sorts of silhouettes, what fantasy will suggest. The same principle applies here: all elements must be used and should not be overlapped.
The drawings show some exemplary figures, although of course you can arrange much more. It is good to sketch each arranged figure on a piece of paper, so that it can be easily reassembled after some time.
