Dr. Lune: Murder Sudoku Game

Who did it? Dr. Lune turns sudoku into a murder mystery: a murder sudoku game where you read the clues, place the suspects on the floor plan and find the killer hiding in the grid.

If you love Murdoku, murder sudoku or logic puzzles with a crime story, grab your notebook, partner: 400 cases are waiting in Paris, Amsterdam, London and Munich.

WHAT IS A MURDER SUDOKU?
A murder sudoku is a logic puzzle with a crime story. Like a classic sudoku, each row and each column holds one person. Unlike a classic sudoku, there are no numbers: only suspects, rooms and clues. Solve the grid and the killer appears.

HOW TO PLAY
1. Read each suspect's clue.
2. Place every suspect on the grid: one per row, one per column.
3. Place the victim last.
4. The only suspect in the victim's room is the killer.
No luck, no guessing: every case is solved by pure deduction.

A DETECTIVE GAME WITH A REAL DETECTIVE
Dr. Lune is an English gentleman detective with a tweed coat and a well-used notebook. You are his partner. He opens every case file, cheers your deductions and helps when you are stuck.

HINTS THAT EXPLAIN, NOT JUST SOLVE
In many murder mystery games, a hint simply places a suspect for you. Dr. Lune shows you why: he points to the clue, highlights the cells that matter and explains the next logical step. You learn the trick and crack the next murder sudoku on your own.
