The performers on this stage line up in a very special way. Using logic, arrange the singers so that every column, every row, and every box of nine squares has nine different singers.

To test whether a full row or full column is correct, click on the judge's shirt found at the end of it.
  



Click on a singer and then on an open space in the grid.
If you make a mistake, use the EMPTY CELL to erase it.
