Rules

• Normal Fillomino Rules:
  Divide the grid into some regions and fill in each cell with a digit that indicates the size of its region. No two regions of the same size may be orthogonally adjacent.
• Variant Yajilin Rules:
  Shade some cells such that each region must be fully shaded or fully unshaded. No two shaded regions may be orthogonally adjacent. Draw a single closed loop that orthogonally passes through the middle of all unshaded cells. The loop may not branch or intersect itself. The loop may not pass through a region twice or more. The digit in the cell with arrow(s) indicates the combined number of shaded cells in all corresponding direction(s). The cell with arrow(s) itself is not counted.
