# Undead – Place Ghosts, Vampires and Zombies – Puzzle Game

In Undead, you are presented with a grid of squares, some containing diagonal mirrors. Every square which is not a mirror must be filled with one of three types of undead monster: a ghost, a vampire, or a zombie.

Vampires can be seen directly, but are invisible when reflected in mirrors. Ghosts are the opposite way round: they can be seen in mirrors, but are invisible when looked at directly. Zombies are visible by any means.

The rules of this puzzle are:

• Place the given numbers of ghosts, vampires and zombies into the empty cells of the diagram
• Ghosts can only be seen in mirrors, vampires can only be seen directly (not in mirrors) and zombies can be seen directly and in mirrors
• The numbers on the edges of the diagram denote how many ghosts, vampires and zombies can be seen looking into the corresponding row resp. column
