What is Super Detective?

Super Detective is a free murder mystery logic puzzle you play in the browser. Each case is a murder in a closed place: a mountain lodge, a night train, a museum. You get the floor plan, the people who were there and a clue or two about each of them. Place everyone on the plan and name the killer.

How do you play?

Every row and every column of the plan holds exactly one person. People stand on free floor or a rug, or sit on a seat, never on other furniture. The killer was the only other person in the victim's room. Use the clues to find each person's square, then point at the killer.

Is it free?

Yes. Five new cases come out every Monday, free and with no sign-up. Anyone who wants more can buy that week's pack of extra cases.

How hard are the cases?

They go from level 1, on a 4×4 plan, to level 5, on an 8×8 plan. Every case has a single solution you reach with logic alone, with no guessing. If you get stuck, a hint shows you the next deduction.

Do I need to install anything?

No. It works in any modern browser, on phone, tablet or computer, and your progress saves on the device. You can also install it as an app and get a notice when new cases come out.
