That's one of my favorite card games. I think using a pattern is clearer than using light and dark colors. The hints are very clever, nicely done.
Thanks for playing! I’m glad you enjoyed it. I’ve been wanting to make a variation of this game for years. This was a great excuse to do it. I ended up going with “light”, “dark”, and “empty” so I only had to make one of each shape. The same graphic is used on all of the cards, which are generated during game play.
