Goal

Place all pieces on the board to exactly fill the target silhouette.

Rules

Select a piece from the tray and drag it onto the board to place it.
Pieces can only be placed within the silhouette area and cannot overlap each other.
Use rotate/flip buttons to adjust piece orientation. Drag placed pieces to reposition them.

Tip

Start from corners and protruding parts of the silhouette to clarify remaining spaces.

Spatial composition puzzles like Tangram train visual analysis and synthesis abilities. They improve geometric understanding and act as protective factors against cognitive aging.
