"Minesweeper" is an old game, that always came standard with the Windows operating systems. Only recently i learned that there exists a Minesweeper "world" on internet (see http://minesweeper.info/).
I made a version of it on the iPad in order to play it right away with the iPad in my hands. The iPad version is somewhat simpler than the official version, but not less difficult. As a lot of iPad owners may not have a Windows PC, i will give a short explanation of this version of the game.

The game is played on a square board, divided in a odd number of little squares. The player is given a choice out of 3 boards (9x9, 15x15, and 21x21).
After selection of the size, a number of mines are placed at random on the board. Then the program inspects each square to count how many mines are neighbouring that square. This number is placed in the inspected square. However, all squares are covered with initially blanc buttons.
Hence, for each button (square) there are three possibilities:
- the button hides a mine
- The button hides a number,
- The button hides a zero (the square has no mines as neighbour)

By touching the buttons, the player unveils the content of the square under it.
The purpose of the game is to discover the positions of the mines wthout touching a button which hides a mine. In a number of cases this can be done entirely by reasoning, in other cases, one or more "blind" choices must be made.

Some examples of reasoning in this game:
- if you hit a square with number zero, then this square has no mines as neighbours. We call this a "white" square. The number zero is not shown, but the button is simply deleted. It is important to realize that you can hit all buttons directly around a white square without the possibility of hitting a mine. If one or more of these neighbours are white squares again, the same procedure can be repeated for each of these white squares and so on, and so on.... a white area appears, surrounded by visible fields with numbers 1 or higher. As this does not require any reasoning, the program does it for you (as does the original M'soft game). So, it is possible that hitting a button may start a running process of unveiling a white area. As a matter of fact, this is a necessary condition to be able to start the reasoning proces.
- If the board contains a square marked "1" and the square has only one hidden neighbour, then obviously that neighbour must be a mine. From that moment you can regard that square as unveiled, although it remains covered by a button.
- If the board contains a square marked "2" and the square has only 2 hidden neighbours left, then you know that both these neighbours must be mines. The same reasoning is valid for squares with higher marks.

The game ends if all squares, not containing a mine, have been revealed. This is a win.
If you hit a mine, that is a loosed game.
The scoreboard displayes the number of games played with each board size, and the number of wins and as percentage of the total.

Upon starting a game, you depend on pure luck for not hitting a mine. At least one white area is needed to be able to start reasoning. For that reason, i will extend the present version (which will no longer be the "final" version) with a facility that a game is not marked as a loosed game if a mine is hit before the first white square (and area) is unveiled (the original Minesweeper shows no mercy at that point).
I will also let the program check each round if mines exist with all squares around it unveiled. In that case the mine will be shown.

In the original game, the time needed to produce a winning game is a record item for the Minesweeper "community". Perhaps i will add that also to the upcoming "final" version

, and keep track of the shortest time for each board size in the scoreboard.

A new "final" version (31-02-2019)

Added:
- loosed games are not counted as such if a mine is hit before a white square was touched
- detected mines are shown
- the use time in seconds is shown in the score window

Code: Select all

Thank you Henko for the detailed explanation. As a mac user I didn't know the game.
I will definitely try it now, hoping it won't become an addiction.

Good plan for ongoing upgrading.
