Divide the grid along the grid lines into regions. Each region must contain one orthogonaly connected area of white cells and one area of shaded cells. The pair of areas must be of the same size, but different shapes. A number indicates how many cells of one color the region contains. A region may contain several numbers - in this case all numbers must be equal.
Grid control: To draw a cut click at the cell edge or move mouse along the line holding the button. You can also connect the centers of cells which belong to the same part with auxiliary line. In this case cut lines will be added automatically. More details about grid control are at the help page.

Shade some cells black and then draw a single non-intersecting loop through all white cells. Black cells should form a set of dominoes which cannot share an edge with each other, but can touch grey and arrow cells. Cells that contain clues or shaded grey are not part of the loop. Numbered arrows in such cells indicate the number of cells shaded black in that direction in the grid.
Grid control: To draw a line press the mouse button at a start cell and move mouse to another cell holding the button. Mouse click at a cell paint the cell black. More details about grid control are at the help page.
