Unlink

Unlink is a logic puzzle game about removing shapes from the cells of a main board by picking one shape at the time from a shape board.
Beware! Shapes can be picked only from the top row of the shape board, and they remove only the matching shapes from the lower row of the main board. Empty cells disappear.
Only shapes that have at least one active match on the main board can be picked.
What is the right sequence of moves to clear both boards?

Also check the Unlink Factor version of the game, which uses numbers instead of shapes and it is even more challenging.
