Place a number into some cells so that all cells with numbers form one orthogonally connected area. Numbers represent how many of the four orthogonally adjacent cells contain numbers. No two orthogonally adjacent cells may contain the same number.
Grid control: Click at a cell reveals the value chooser. Click at the selected value changes the state of the cell. More details about grid control are at the help page.
