Logical Puzzles

What logical puzzle questions look like

Logical puzzle questions give you a set of constraints — usually about people, positions, or attributes — and ask what must be true, what cannot be true, or who occupies a specific position. Three main formats: 1. Grid/attribute puzzles: assign attributes (specialties, hospitals, shifts) to people based on clues 2. Sequencing puzzles: order people or events using relative position clues 3. Truth and lies puzzles: determine who is lying when a fixed number of statements are false
