A MINESWEEPER puzzle consists of a square or rectangular grid in which a number of mines have been laid. Some of the cells contain a hazard flag which has a number indicating how many of the adjacent cells (horizontally, vertically and diagonally) contain a mine. To solve the puzzle, you must determine which of the un-flagged cells contain a mine. Each puzzle has a unique solution and no guessing is required to reach a correct solution.

WARNING!

You must use a Java enabled browser to solve this puzzle.

Enabling your browser is quite a simple matter, requiring only a few minutes to complete the following steps:-

Begin by downloading and installing the Java Runtime Environment. This is a small program which is available free from the ORACLE web-site at
http://www.java.com/en/download/manual.jsp
In most cases you will probably also need to change your browser Preferences to actually enable Java processing. The steps involved here will depend on the browser you are using. Details of the actual steps for most popular browsers are provide by the ORACLE web-site at

Solving a MINESWEEPER puzzle is a mouse only operation. A single click in any PENDING (gray) cell will convert that cell to a CLEAR cell (no MINE) which has a default color of white. A second click will convert it to a MINE cell, and one more click will convert it back to a PENDING cell.

If the going gets too hard, use the Request a Hint function. This will highlight one or more cells where further solving activity can take place. In addition a pop up Help screen will appear explaining the strategy to be used at that point. If you don't see this Help screen, you will need to reconfigure your web browser.
