Your goal is to mark positions of all mines on the board. At the beginning all fields are covered, you can uncover them by pressing 5. There are three types of fields you may uncover:
1 - a bomb (bad luck, you lose)
2 - empty field (this means there are no bombs around, automaticly all neighbouring fields will be uncovered)
3 - empty field with number on it, telling how many bombs are around (on 8 neighbouring fields)
The clue of the game is deducing bomb's positions basing on information about numbers of bombs around uncovered empty fields. When you are sure that there is a bomb on a specific field, you can mark it by pressing 0 (you can unmark it later by pressing 0 again). You win if you mark all bombs correctly without marking any non-bomb fields. You don't need to mark all bombs, sometimes it's enough if you leave bomb-field unmarked and uncover or correctly mark all neighbouring fields.
Your skills will be measured by time you need to mark all bombs - the faster the better.
Controls:
Keys: 1 - up/left; 2 - up ;3 - up/right; 4 - left; 6 - right; 7 - down/left; 8 - down; 9 - down/right; 5 - uncover field; 0 - mark/unmark field

Have fun, and remember: minesweeper makes mistake only once in a lifetime!!! :)
