A challenging combination of Rubix cube logic and Portal cubes of every variety found in the games. The six colours make the cube fully playable as you puzzle to align the coloured bars with their matching centerpieces. All cornerstones are identical, but this does not make things less difficult, as I quickly discovered before I spent hours trying to get it back into shape for these product shots.

Each face features a different cube from the Portal games:

• Gray: Standard Storage Cube
  
• Blue: Inactive Storage Cube
  
• Yellow: Activated Storage Cube
  
• Pink: Companion Cube
  
• Green: Discouragement Redirection Cube
  
• Red: Laserbeaming Discouragement Redirection Cube
