Logical Puzzles

Logical puzzles are one of the most common question types in the UCAT Decision Making subtest. These questions present a set of constraints (rules or conditions) and ask you to determine what must be true, what could be true, or what arrangement is valid. This lesson teaches you a systematic approach to solving them efficiently under time pressure.

What Are Logical Puzzles in the UCAT?

Logical puzzles in the DM subtest typically involve:

• Scheduling problems — arranging events, appointments, or activities in a sequence
• Seating arrangements — placing people around a table or in a row according to rules
• Ordering problems — determining the correct sequence of items based on comparative clues
• Allocation problems — assigning people to teams, rooms, or tasks based on constraints
• Matching problems — pairing items from two or more categories (e.g., matching people to hobbies and locations)

These questions usually provide 4-6 constraints and ask you to determine which arrangement satisfies all of them, or to identify which single statement must be true.
