One line. Every square. Drag a single unbroken path that fills every square on the board and passes through the numbers in order. Simple to learn. It does not stay simple. Every board carries a real difficulty rating, measured from the reasoning it actually takes to solve. So do you. The better you get, the harder they come. There is no ceiling, and you will never see the same board twice. A new puzzle for the whole world every day. Solve it fast. Keep your streak. Daru walks the route you draw.
