While I was seeking for the theme of my game, the nine-node maze lock of an Android phone reminded me the shape of magic circle. Connecting with my experience before that my friends and I made jokes by locking others' phone with complex patterns, I thought it has potential to be a new mechanism of a competitive game. As the result, I set the background to a magic age that wizads will use magic to link the mega diamonds and create magic circles to seal competitors.
