Shade some cells black to create a snake - a chain of blackened squares which doesn't touch itself even at a point. Begin and end of the snake are already given. Clues represent the total count of occupied neighbouring cells, including diagonally adjacent cells. Snake cannot pass through cells with numbers.
Grid control: Click the mouse button at the selected cell to change the color of the cell. Second click will put auxiliary cross sign, which doesn't affect correctness of the solution, but helps visually. You can also drag the content of one cell to another with the mouse. More details about grid control are at the help page.

Draw few rectangular loops through the centers of unshaded cell so that every unshaded cell is used. The sides of different rectangles may intersect each other, but not turn at their intersections or otherwise overlap. Numbers outside the grid show the length of the longest line in the corresponding row/column.
Grid control: To draw a line press the mouse button at a start cell and move mouse to another cell holding the button. More details about grid control are at the help page.
