方形拼图

This Square Puzzle can only be put together 1 way by using all of the pieces. It is possible to make a square using 4 of the pieces, but all pieces must be used for the puzzle to be completed and correct. (See the images).

You have seen the solution. Those who have not, may find it very difficult to solve.

Give it to people to test them.

Printing time for the small version is around 1 hour.
