A puzzle from 1898.  Copy of "Le Fermier Avisé" from "The book of ingenious & diabolical puzzles", Jerry Slocum and Jack Botermans Place the 9 cardboard pieces in a square of 3 x 3 pieces. Where 2 numbers lie against each other, the sum must always be the same. So: In each square cage the same number of chicks. To make the puzzle more beautiful I made adjustments,

16 cardboard pieces,Make a magic square.

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. If you carefully open the puzzle you will see a 4. Remember that.

Put the strings in order.

Try to open the puzzle by removing the 4 cylinders with the numbers. (2014 is year of design) If you have problems to open it, use the green tool.But try to find out why this tool is  in the BOX!!!GOOD LUCK!
