Case 16: Murder Sudoku

A murder, a floor plan, and a clue from every suspect. Put each suspect on the square where they stood: one to a row, one to a column. The victim was alone with the killer, so whoever shares their room did it. No guessing, no luck — every case has exactly one answer, and you can reach it by reasoning alone. THE RULES FIT ON A CARD • One suspect to every row and every column. • "Beside" means left, right, above or below — never diagonal, never through a wall. • Nobody stands on furniture. Tables, plants and boxes are solid; chairs, beds and carpets are somewhere to be. • The victim was alone with the killer. Their room holds exactly two people. 80 CASES, EASIEST FIRST From a 5×5 warm-up to 12×12 boards that take a whole evening. Bars, ferries, hospitals, film sets, a reading of the will. Every difficulty is measured from the steps it takes to solve, not guessed, so the case number is the ladder. A NEW CAST EVERY CASE Suspects are dealt fresh for each case — different faces, clothes, hats and habits — so you are never solving the same five people twice. THE MONTHLY CASE Once a month, one big 12×12 case and one attempt. Fastest times go on the ranking. HINTS THAT TEACH Stuck? A hint shows the next step of the deduction and why it follows — never just the answer. FAIR ABOUT ADS Every case is free, and ads pay for them. A hint plays a short ad first; leaving a case you have just solved plays one. Opening a case may play one too, but an ad never interrupts a case in progress, and time spent on an ad never counts on your clock.
