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.
All numbers are in a slide.Slides from left to right. Under number 4 is the free hole. A difficult puzzle, but it can be solved. Assignments on the back of the puzzle.Material acrylic.
