Shadow Detective

Match an outlined geometric shape to its exact silhouette. Notice every edge, notch and allowed quarter-turn.

How to play

Choose the matching shadow. First the shapes point the same way; later you can Rotate preview to compare quarter-turns. Flipping a shape over is different. Use Describe shapes to hear its rows.

Follow the outline's edge. The right shadow has every filled space in the same place, or in an allowed quarter-turn. After matching, an orange outline shows how the edges fit. Undo and a little hint are always nearby.
