Do Not Try This At Home...
While these games might seem like simple dares or tests of bravery - chanting in front of a mirror, riding an elevator alone, taking pictures in the dark - you may be joined by unexpected playmates. They may promise otherworldly knowledge or contact with the other side, but nothing is without its cost.
If you choose to ignore this advice and play the games locked in this book, just remember: What you summon may not want the game to end.
