What This Game Is
Undead is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.
Place ghosts, vampires and zombies so that the right numbers of them can be seen in mirrors.
How to Play
Undead has a similar control system to Solo, Unequal and Keen. To play Undead, click the mouse in any empty square and then type a letter or number on the keyboard indicating the type of monster: ‘G’ or ‘1’ for a ghost, ‘V’ or ‘2’ for a vampire, or ‘Z’ or ‘3’ for a zombie. You can also click on a monster in the counts at the top to place it in the highlighted square. If you make a mistake, click the mouse in the incorrect square and press Space to clear it again (or use the Undo feature).
Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.
Beginner Tips
- Start with the area that has the strongest clue or the fewest legal options.
- Use marks, notes, or temporary indicators if the puzzle supports them.
- Try to preserve flexibility instead of committing too early when multiple moves look possible.
- If the board gets messy, restart a fresh puzzle and apply what you learned from the first run.
