Separate the 2 parts and slide back to start!
After completion of this puzzle, by dutch designer Oskar, the words “Key” and “Ring” should be properly lined up with each other. If you try to put the pieces back together without lining up the words correctly, you will have failed even after achieving what appears at first to be a successful matching. It should read “Key Ring” even when upside down.
