Recently, I have seen that many players often encounter some minor problems. Here I would like to share with you a mine-clearing technique and a line of reasoning. Before continuing to read the post, I hope everyone can have a clear mind, and I will try to explain it to you as concisely as possible.

The text is very long, so you can just use the bold conclusion, but I personally recommend that you have a thinking process and enjoy the joy of thinking.

For example: This is a very common situation where 1 and 2 are tied. ①The 1 in the white box indicates that there is a mine in the three squares to the right of it; furthermore, there is only one mine in the two squares in the white box at most.

② If there is no mine in the white box, then the 2 in the white box cannot be satisfied; therefore, there must be and only one mine in the two cells of the white box.

③Since there is a mine in two squares in the white frame, and 1 in the white frame is satisfied, the square under the white frame is safe; similarly, there must be a mine in the square above the white frame.

This solution is what I personally call "advance results". It does not focus on details, but refers to Doge Youlei's inference as a whole, and uses uncertainty to obtain other certain results, and then in turn solves the answer. The common 121 formula can be derived from this reasoning.

For another example, this time, from the two 3s in the middle and right, we got the positions of the four mines. Using "advance results", the following reasoning can be made:

①The 3 on the left indicates that there must be a mine in the two squares in the red box.

② A mine in the two cells of the red box and a mine on the right side of the number 2 meet the requirements of the number, then all three cells in the green box are safe.

I hope you can use this skill and enjoy the game
