QUITTING
--------
To quit, left-click on the close box in the top left corner, or select
"Quit" from the Game menu.
PLAY
----
Use the game menu to select a board size. (Only 25x14 games are scored;
see the SCORING section, below.) The game shows a grid of concealed
cells, each of which is either mined, or safe. Just above, there are two
numbers; the left number shows the time taken during play; the other is
the number of unexposed safe cells. Also, when the game ends, "You win"
or "You lose" is displayed above the grid.
To win, you must expose all safe cells. If you win, your score is
the amount of time taken; if you lose, your score is infinity. Low
scores are good. (In traditional minesweeper, you must mark all mined
cells. This game is different, and in more than this way.)
Use the left mouse button to expose a cell. To mark or unmark a cell,
use the right mouse button, or hold down a shift key and use either
mouse button. A marked cell cannot be exposed. Marked cells contain a
colon.
When an empty cell is exposed, it shows how many neighbouring cells are
mined. But if there are no neighbouring mined cells, the neighbouring
cells are exposed. The numbers can be used to deduce the locations of
safe and mined cells.
When a mined cell is exposed, you will probably lose. But if it is
impossible to deduce that the cell is mined, and impossible to deduce
the location of a safe cell, the mine is exposed, and the game
continues. (There is a brief pause while the program studies the
displayed position; during the pause, the player's clock is stopped.)
Exposed mines appear as an asterisk.
If the player clicks on a mine and loses, the program shows all mines,
and shows all cells that it could deduce from the exposed information.
This table specifies the appearances of cells after the deduction.
unexposed cell background character
----------------- ---------- -----------------
safe, unknown gray none or colon
safe, known green none or colon
mine, unknown purple asterisk or colon
mine, known yellow asterisk or colon
mine, known, clicked red asterisk or colon
SCORING
-------
The scoreboard may be displayed with the "Show scores" menu selection,
but not while a game is in progress.
The scoreboard shows statistics for the 25x14 games.
in red: the top ten scores of all time
in yellow: the top ten scores of this week
in green: the top ten player averages
A player average is actually the harmonic mean of the player's scores,
where a loss scores as infinity. A player's scores are weighted; recent
ones count more than old ones.
CONFIGURATION
-------------
The player may specify various parameters of the game in the
minesweeper.config file with lines like these:
djr.minesweeper.scorefile=minesweeper.score
djr.minesweeper.name=me
The `scorefile' parameter specifies the score file.
The `name' parameter indicates the name to appear on the scoreboard,
when the player scores well enough. The first seven characters are used.
Use a text editor to create or alter the minesweeper.config file. The
lines must appear exactly as shown up to the first equal sign. The
parameter values shown above are also the defaults.
COMMAND LINE PARAMETERS
-----------------------
For CLI users, all of the configuration parameters may be entered on the
command line. For example:
run minesweeper scorefile=df0:scores name=Fred
starts the game; "Fred" will appear on the scoreboard "df0:scores" if a
good score is achieved. Command line parameters take precedence over
configuration file parameters.
Workbench users must use IconX, if this feature is needed.
