Rules of Four Cells:
- The grid is to be divided along the grid lines into areas containing exactly four cells.
- A number in a cell indicates how many of its four sides are segments of area boundaries. Note that this also includes the border of the grid.
- Line segments of area boundaries should not be left dangling. (See below for an example)
- An area may contain any multiple number cells (including none).
An example grid is shown below for greater clarity.
