How to Get Hints

A copy of your puzzle's grid is shown on the left. Copy over your current grid state from the book into the grid on the left by clicking once in a square to make an 'X' or twice to make an 'O'. Once you have your current grid state represented here, you can click the 'Hint' button below the grid. This will (1) remove any errors in your current grid state and (2) offer a suggestion as to where the next logical deduction can be made. You can request unlimited hints.
