Two ways to compare shapes
Choose a mode and focus on the object's spatial structure.
See how the blocks connect
Shapes remain clear so block positions and connections are easy to inspect.
Find the single matching object
Study the target and select the one option that can overlap it after rotation.
Decide same or different
Compare two views and decide whether rotation alone can make them overlap.
One clear answer per question
Reflections and structural changes appear only as distractors, so each question has one correct answer.
Move naturally to the next question
After each answer, the correct choice appears briefly before the next question.
Separate records for each mode
See your latest result, personal best, and change from the previous test for each mode.
Frequently asked questions
The difference between the modes
Match asks you to find one matching option. Pair asks whether two shapes are the same or different.
How two shapes count as the same
Two shapes are the same when rotation alone can make them overlap. A reflection or structural change does not count.
Why some shapes look similar
Some shapes are reflections or connect differently. They may look close, but rotation cannot make them overlap.
Starting and answering
