## What is Case 16?

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.
