The most difficult puzzle I have designed. The puzzle consists of 15 pieces. Some pieces can be slid under the edge. Goal: Make the numbers 1 to 9 from left to right in the frame There are different possibilities. But there is only one possibility to slide to a magic square. The numbers are engraved in the pieces. Material acrylic.
If you carefully open the puzzle (press the bottom of the title square piece) you will see a 4. Remember that.
The original puzzle is called "Question du Lapin" made by WATILLIAUX around 1900. The puzzle was republished in cardboard in 1985 by a Dutch magazine "Margriet". They changed the flower and the flowerpot into a whale and a chicken.I made this on transparent overhead sheet. In 1993 you were still allowed to come with a copy. Nowadays you have to participate with your own design.
