| In this example we start with a beginner difficulty level. The number of remaining mines is on the digital display in the top-left corner of the minesweeper board. Let’s start by left-clicking on the randomly selected square. In this example we choose the square marked on the picture with a red circle. |
| After the initial click, a number of squares are uncovered. Some of the uncovered squares have numbers in them, some of them are empty. The numbers indicate how many mines are hidden beneath the surrounding covered squares. Notice the square with 1 in it, market by a red circle. There is only one uncovered square adjacent to it (marked with a brown circle). And since there is only one adjacent mine, the mine must be beneath this covered square. Let’s plant a flag on this square by right-clicking on it. |
| Now that we planted our first flag, we can uncover more squares. Take look at the square with the 1 in it, marked with the red circle. We know that there is only one mine in all three adjacent squares above it. But we have already found this mine and marked it with a flag. This means that in the two remaining squares (marked with brown circles) there is no mine. We can safely uncover them by left-clicking on them. |
| Now we are ready to plant our second flag. As before, we can find a square with 1 in it (marked with a red circle), which has only one covered square around it (marked with a brown circle). The mine must be there and so we can safely plant a flag by right-clicking on this uncovered square. |
| After planting the second flag, we again notice squares with 1s in them, which already has flags in their neighborhood. Two of such squares are marked with red circles. Since both of them already has one flag close by, thus there cannot be a mine in the other uncovered squares adjacent to them (marked with brown circles). We can left-click on these fields to uncover them. |
| Again, there is a square with a 1 in it for which the adjacent mine has already been found. Let’s left-click on the only remaining uncovered square (marked with a brown circle). |
| After uncovering the two squares mentioned above, we noticed that the square above the flag on the right also has 1 in it, and so we can uncover the square to the left of it, which reveals number 2. Now let’s pay attention to the 3 marked with a red circle. There are three mines in the adjacent squares. And there are three uncovered adjacent squares in total: one on the left has already been marked with a flag and the remaining two up top are still uncovered. There is no other way – the two uncovered squares must contain mines so that there are three mines in the squares adjacent to the digit 3. Let’s plant flags in these two squares. |
| Now let’s pay attention to the two squares containing digit 2, marked with red circles. Both these squares have only two adjacent uncovered squares, marked with brown circles. These two adjacent squares must therefore contain mines. Let’s plant our flags there. |
| Now we can identify some squares which already has appropriate number of mines flagged around them. The two examples are marked with red circles. Since the number of mines in adjacent squares matches these digits, it means that remaining uncovered squares cannot contain mines. We can thus uncover them by left-clicking on them. |
| One of the newly uncovered squares (marked with a red circle) contains digit 2 and has only two uncovered squares around it, one of which is already marked with a flag. We can mark the other square with a flag. |
| In the next step, we see three squares with digit 1, all of which already have a mine in one of their adjacent squares. All other adjacent squares can be than safely uncovered. These squares are marked with brown circles. |
| Now let’s focus on the digit 2 market with a red circle. As before, it has only two uncovered squares around it, one of whom has already been marked with a flag. We can thus plant the flag in the other one (marked with a brown circle). Notice that as we do it, our mine counter in the top-left part of the minesweeper board indicates that the remaining number of mines drops from one to zero. This means that we can safely uncover all remaining squares as they surely do not hide mines beneath them – all mines have been already found! |
| The game is won! The time counter in the top-right corner of the minesweeper board indicates that it took us exactly three minutes to complete the game. |
