**<The m by n
Black-Out Game Simulator>**

**<How to
use>**

The Black-out game can be used easily and we give here simple instructions. The first step would be to input the size of the matrix and it depends on our choice. Let us assume that our choice is a
7x9 black-out game. - White Cells.
- Green Cells
- Black Cells
When the blackout game generates a singular block tridiagonal matrix (for example, 4x4, 5x5, 7x5 cases), this tool can't obtain any solutions. For this case, we had prepared another tool to find a solution in the blackout game for the singular case as below. http://matrix.skku.ac.kr/NewJAVA/BlackOut/Test.html [For the general blackout game] |

**<For the case of det(A)=0, try the following tool>**
