Blue Prince has a slew of little puzzle boxes all over the house, each with a different collection of colorful blocks. In order to win, you need to figure out what all those different colored blocks do and how to move them around to get them in the right places.

In the Solarium, you will find one of these Mora Jai boxes, and this one is a Nuance puzzle box. This means you will need to get green in each of the four corners before you can get it open.

How to Solve the Solarium Mora Jai Puzzle Box in Blue Prince

Like all the other Mora Jai boxes in Blue Prince, the Solarium box has different colors in each of the nine squares. Each color moves differently than the other colors, and there are three in this box. There are two gray boxes, several green boxes, and three yellow boxes.

  • Green boxes move to the opposing block when clicked.
    • Green boxes in slot 1 will exchange places with 9 and vice versa.
    • If a green box in slot 7 will change places with box 3 and vice versa.
    • 2 and 8 greens will also change places with each other.
    • 4 and 6 are also considered opposites.
    • If slot 5 is green, it will stay where it is when clicked.
  • Yellow boxes move up one when clicked.
  • Gray boxes do nothing.

Given all of these rules, you need to move the yellows to the middle in the right and left column. Here are the order you need to click the boxes in to get this to happen. It is not the only way to do this one, but it is an easy way to make sure you beat the box in the Solarium floorplan in Blue Prince.
