Puzzle questions present a small set of people, objects, places, or events and ask you to arrange them using the given clues. This topic commonly includes grid puzzles, floor-based arrangements, and scheduling problems.

Common puzzle types

• Grid puzzles: match people with attributes such as colors, cities, or jobs.
• Floor-based puzzles: place people or objects on numbered floors.
• Scheduling puzzles: assign activities to days, times, or dates.
• Ordering puzzles: arrange items by rank, age, height, or sequence.
• Distribution puzzles: allocate objects or tasks according to conditions.

Start with a diagram

Draw a table, row of boxes, floor diagram, or calendar before solving. Write fixed information first, then add deductions from relative clues. A clear diagram prevents repeated reading and makes contradictions easy to spot.

Reading common clues

• Immediately before or after: the two positions are consecutive.
• Between: one item has a position on either side of another item.
• Not next to: adjacent positions are not allowed.
• More or fewer: use an ordered scale such as floors, days, or ranks.
• Either-or: keep both cases open until another clue eliminates one.

A reliable solving method

1. List every person, object, and available position.
2. Place direct facts and fixed positions first.
3. Link clues that share the same person or attribute.
4. Use elimination to fill remaining slots.
5. Test tentative cases only when a clue creates two possible arrangements.
6. Verify every clue against the completed arrangement.

Useful shortcuts

• Mark impossible pairs with a cross in grid puzzles.
• For a five-floor building, remember that top is floor 5 and bottom is floor 1.
• Use a short block for linked clues, such as A-B for “A immediately before B.”
• Do not assume a missing detail; leave it open until a clue fixes it.
• When two cases remain, test the more restricted case first.

Common mistakes

• Reading “before” as “immediately before.”
• Reversing top and bottom in floor questions.
• Forgetting that each person or object is used only once.
• Choosing an answer before checking every clue.
• Using real-world assumptions instead of the stated conditions.

Quick revision summary

• Use a diagram that matches the puzzle type.
• Start with fixed facts and the most restrictive clues.
• Use elimination and controlled casework.
• Confirm the final arrangement against every condition.
