If it is not difficult for us to assemble a puzzle of several dozen elements, then puzzles of a thousand or more pieces turn into a real difficult puzzle. Although this makes it even more interesting.
Ideally, take a large piece of paper and draw the boundaries of your puzzle on it. Its dimensions are usually written on the box.
Start laying out the puzzle from the frame. These puzzle pieces are always distinguished from the rest by their straight sides. Select these pieces from the total mass. First, put elements with two straight sides in the corners, and then lay out the remaining frame.
To make the puzzle easier to assemble, pay attention to the location of the bumps on the puzzle pieces. These bulges are either straight at the ends or beveled. Let's say the beveled ends end up at the top and bottom of the picture all the time. And if you are not sure how to unfold this or that piece in the puzzle, remember that elements with beveled bulges should be vertical, and elements with straight ones should be horizontal. And vice versa.
Some smooth bumps may be slightly flattened. Flattened flat and regular flat elements can only be found in one row / column, but not in different ones.
Finally, if the picture has explicit objects, put aside the elements associated with it. They are easier to collect. And leave the most difficult (the sky, for example) for last.
