How to play
Fill all six slots with the unique monster assignment that reproduces every encoded direct and reflected visibility count.
- Six slots begin unknown, and immutable ray records state how many monsters each direct or mirror segment can see. The generated evidence identifies one assignment.
- Set an editable slot to ghost, vampire, or zombie, or clear it. Vampires count on direct sight, ghosts count in mirrors, and zombies count in both kinds of segment.
- Fill all six slots with the unique monster assignment that reproduces every encoded direct and reflected visibility count.
Strategy tips
- Compare a direct observation with its mirrored counterpart: a direct-only sighting indicates a vampire, mirror-only indicates a ghost, and both indicate a zombie.
- Counting a ghost on an unreflected segment or hiding a zombie from a mirror reverses the defining visibility rules and creates contradictions across paired rays.
- For the last unknown slots, total every ray they participate in rather than relying on monster counts alone; each remaining value must satisfy both viewing modes.

Rules, scoring, and strategy
Undead Puzzle is a complete browser implementation with its own versioned rules profile. Assign ghosts, vampires, and zombies to six hidden slots by reconciling direct and mirrored sight lines whose counts depend on which monsters are visible.
Legal moves and game flow
Set an editable slot to ghost, vampire, or zombie, or clear it. Vampires count on direct sight, ghosts count in mirrors, and zombies count in both kinds of segment.
Winning and terminal positions
Fill all six slots with the unique monster assignment that reproduces every encoded direct and reflected visibility count. For the last unknown slots, total every ray they participate in rather than relying on monster counts alone; each remaining value must satisfy both viewing modes.
Practical strategy
Compare a direct observation with its mirrored counterpart: a direct-only sighting indicates a vampire, mirror-only indicates a ghost, and both indicate a zombie. Counting a ghost on an unreflected segment or hiding a zombie from a mirror reverses the defining visibility rules and creates contradictions across paired rays.
