Solve Meijer's box

The first thing to do to solve Meijer's Box, is to get all parts in the box, so that the locking mechanism can be applied.

To fill the box

The solution

Place the box in front of you with the open side pointing up and the side with the hole pointing towards you. Place parts D, E, F and G on the bottom of the box as shown in the image. Join parts A, B and C together as indicated and place them in the box on top of the first parts. Everything now fits in the box, with only part A sticking out.

To lock the parts

To get part A in place, the following sequence is required. Part C moves forward, so that it fills the hole in the side of the box. This part now acts as a lock that prevents the other parts from falling out when the box is held upside down. Part D moves up, part G moves back and part F moves to the right, allowing part A to drop in place. To lock part A when the box is held upside down, part E then moves to the left.

  1. Start with the box in front of you, with the open side pointing up and the side with the hole pointing towards you.
  2. Rotate the box towards you over 360 degrees.
  3. Rotate the box to the right over 90 degrees.
  4. Rotate the box to the left over 180 degrees.
  5. Rotate the box to the left over 90 degrees, to hold it upside down without any parts sticking or falling out.

To unlock the parts

To unlock the parts the lock sequence should be reversed. Part E has to move to the right. Part A can then move up, so that parts F, G and D can be moved to their original position. Finally, part C can be moved back, unlocking the other parts.

  1. Start with the box in front of you, with the open side pointing up and the side with the hole pointing towards you.
  2. Rotate the box to the right over 270 degrees.
  3. Rotate the box towards you over 90 degrees.
  4. Rotate the box to the right over 180 degrees.
  5. Rotate the box to the right over 90 degrees, to hold it upside down so that the parts will drop out.
