After you start Crossmines, the high score table displays.
Select New Game at the top-left.
New Game button
In the 'New Game' box, you choose the type of game you want to play.
New Game box
These options are covered in more detail on the new game options page, but for now, just:
Identify all the cells that contain mines, without activating any of them. Do this by testing cells, or marking them as containing a mine.
A newly-started game
Hover your mouse pointer over a cell - the cell under your pointer will pulse white. Left-click to test the cell.
One cell tested
One of two things will happen:
* Your first test is generous: if you trip a mine on your first test, it will not trip the minefield - instead, the cell will be marked.
With one cell tested, numbers are revealed (when you test a 'zero' cell, exploration happens automatically when it is safe to do so, and many numbers are revealed).
Right-click to mark a cell.
Obvious Cells Marked
In this example, the marked cells are those where a '1' implies that its only unexplored adjacent cell contains a mine.
Continue until all mines are identified.
