Place all pieces on the board to exactly fill the target silhouette.
How to Play
Tap a piece in the tray below to select it
Drag the selected piece onto the board to place it where you want
Use rotate/flip buttons to adjust piece orientation
Core Rule: Place Inside the Silhouette
All pieces must be placed inside the silhouette (gray area). Pieces cannot extend beyond the silhouette boundary!
Core Rule: No Overlapping
Pieces cannot overlap each other. Each cell can hold only one piece at a time.
Completed Example
Use all pieces to fill the silhouette completely with no gaps
Pieces can only be placed within the silhouette area and cannot overlap
Drag placed pieces to reposition them on the board
Tip
Start from corners and protruding parts of the silhouette to clarify remaining spaces
Place larger pieces first — it's easier to fit smaller ones into leftover gaps
Stuck? Tap the hint button to reveal the correct position of one piece
Spatial composition puzzles like Tangram train visual analysis and synthesis abilities. They improve geometric understanding and act as protective factors against cognitive aging.
