shade

The goal of shade is to draw the right boxes to clear the board.

Trace a box by dragging from one corner to another.

The parts of boxes that overlap will be darker.

Tip: every move you make will have to overlap the darkest area on the board.

====================

Try changing the focus mode and your moves must be split between different highlighted squares for an added level of strategy.

They must include one and only one of these squares each time.
