Colour some squares black, so as to meet the following conditions:
|
||
|
|
<ul>
|
||
|
|
<li>
|
||
|
|
No two black squares are orthogonally adjacent.
|
||
|
|
<li>
|
||
|
|
No group of white squares is separated from the rest of the grid by
|
||
|
|
black squares.
|
||
|
|
<li>
|
||
|
|
Each numbered cell can see precisely that many white squares in
|
||
|
|
total by looking in all four orthogonal directions, counting itself.
|
||
|
|
(Black squares block the view. So, for example, a 2 clue must be
|
||
|
|
adjacent to three black squares or grid edges, and in the fourth
|
||
|
|
direction there must be one white square and then a black one beyond
|
||
|
|
it.)
|
||
|
|
</ul>

|
with a dot, if you know it should not be black.
