How to solve the case

Read the board

Houses 1–5 run left to right. Every row has one unique value for each house.

Place the evidence

Tap a tile to cycle through the options. A value moves if you place it in another house.

Follow the case notes

Use each clue to eliminate possibilities. Tap a note after you have accounted for it.

Submit your deduction

You have five checks. Correct tiles receive a green seal; wrong tiles receive a red one.

Close the case

Complete all 25 tiles correctly to identify who has the map. The answer is hidden in the case board.

Investigator’s note. Start with fixed facts: Singh is in room 1, and the center room contains lemonade.
