Sudoku1 - Variante Naval Fight

Variant : Naval Fight

This variant is based on the famous naval battle game, in which several boats of different sizes are placed in the grid. Each boat can not touch another boat, even by angles.

Boats can be horizontal or vertical, and are therefore placed in a row or column.

At the beginning of each row and column, are indicated the total number of cells where there is a boat.

Your goal is to find the boats to solve Sudoku grid.
By pushing the button Found of the toolbar, the number of cells remaining in a row or column is reported in terms of the number of boats. For example: 6-2 indicates that there are 6 cells with a boat, with 2 remains to be found. Likewise, a boat is green if there is only one possible solution for its placement.

By pushing button "Variant-> Possible" of the toolbar, possible values are filtered using combinations available, if only one possible solution. In the resolution methode, select the method "Variant" to take into account these combinations.

You can specify in a cell that a boat awaits, that the box is empty or undetermined by clicking on the left button of the mouse. Warning, "Clears All Boats" set all grid cells in a status undetermined.

Here is an example of grid:
