Place each suspect exactly once in every row and every column.
Use the Witness Statements to figure out which room each suspect was in.
Squares containing furniture are blocked — no suspect can stand there.
The victim icon marks the crime scene. The culprit is the one suspect in a cell directly beside it (up, down, left, or right).
Select a suspect from the tray, then tap a cell to place them. Tap a placed suspect to pick them back up.
Tap the ✕ button in the tray to enter mark mode — then tap any empty cell to cross it out as a reminder that no suspect belongs there. Tap again to remove the mark.
