Start by dragging one of the chromosomes to an allowed position on the metaphase plate (P1 to P4). When you drop the chromosome on an allowed position, you should see the box underneath the chromosome turn green as well as receive a congratulatory popup-box message. If you try dropping a chromosome on an incorrect position, the box will stay yellow and you will be given another chance to place the chromosome.
Please try to explain why only some arrangements of chromosomes are possible due to the process of independent assortment that happens during meiosis.
