This is what im getting but stuck like every one else. iv found this on wiki not sure if its any use and im sure others have allready tryed or looked at it.
Contradictions[edit]
Some more difficult puzzles may also require advanced reasoning. When all simple methods above are exhausted, searching for contradictions may help. It is wise to use a pencil (or other color) for that to facilitate corrections. The procedure includes:
Trying an empty cell to be a box (or then a space).
Using all available methods to solve as much as possible.
If an error is found, the tried cell will not be a box for sure. It will be a space (or a box, if space was tried).

In this example a box is tried in the first row, which leads to a space at the beginning of that row. The space then forces a box in the first column, which glues to a block of three boxes in the fourth row. However, that is wrong because the third column does not allow any boxes there, which leads to a conclusion that the tried cell must not be a box, so it must be a space.
The problem of this method is that there is no quick way to tell which empty cell to try first. Usually only a few cells lead to any progress, and the other cells lead to dead ends. Most worthy cells to start with may be:
cells that have many non-empty neighbors;
cells that are close to the borders or close to the blocks of spaces;
cells that are within rows that consist of more non-empty cells.
Deeper recursion[edit]
Some puzzles may require to go deeper with searching for the contradictions. This is, however, not possible simply by a pen and pencil, because of the many possibilities that must be searched. This method is practical for a computer to use.
Multiple rows[edit]
In some cases, reasoning over a set of rows may also lead to the next step of the solution even without contradictions and deeper recursion. However, finding such sets is usually as difficult as finding contradictions.
Multiple solutions[edit]
There are puzzles that have several feasible solutions (one such is a picture of a simple chessboard). In these puzzles, all solutions are correct by the definition, but not all must give a reasonable picture.
