Deductive logic · Missing shapes
Aon gapChallenge practice
Find the one shape that must replace the question mark. Build speed through a continuous six-minute run, or work through six untimed puzzles with clear deductions after each answer.
Before you start
- Each shape appears exactly once in every row and every column. There are no smaller box rules or diagonal rules.
- Find the shape for the ? cell. Other empty cells may help your deductions, but you only answer the question mark.
- Selecting an answer shape submits it immediately. The next puzzle opens straight away, and you cannot return or skip.
- The six-minute clock runs continuously, including background tabs and reloads. There is no pause or question limit.
Use the optional pencil marks to work through other empty cells. Pencil marks never count as answers and are cleared when you reload.
Original 4 × 4 and 5 × 5 practice puzzles. Their difficulty progression is designed for preparation and has not been calibrated against Aon’s assessment or employer pass marks.
