After playing the Lunar Phase Game today, I realized that I need to provide an reference document or answer sheet because both people playing the game with me did not know whether the lunar phase picture and name were a match or not when I placed my "pair" on the table.
Secondly, the lunar phase picture card looks the same for the first and third quarters depending on how you turn the card. I decided that's okay, but I just didn't realize it when I made the game.
Perhaps that why you should PLAY THE GAME, and not just visualize it in your head. I'll design a reference document (labeled pictures of the moon phases) and post it soon.
