Center and Symmetry

Pick a mode, then click Start. You'll see 8 shapes, one at a time, in a random size, position, and rotation each round.

Find the Center: click where you think the middle of the shape is. You're scored 100% for an exact hit, falling off the closer you get to the shape's own edge.

Draw the Line of Symmetry: click and drag across the shape to draw a line. You're scored on both how well its angle matches a real symmetry line and how closely it passes through the center (a circle has infinitely many symmetry lines, so any angle counts there). After each shape, the true answer is revealed alongside yours. Your final score is your average accuracy across all 8 shapes.
