'Explainable Mine Sweeper' is a teaching material that forces you to play only logically by completely eliminating uncertain factors, and can improve your basic skills.

In ' Mine Sweeper ,' the player is asked to search for hidden mines by displaying a hint on the number of mines in adjacent squares in squares that do not contain mines. When playing, the player may have to click on a square by guesswork because the hints are insufficient, but a new minesweeper called ' Explainable Minesweeper' has been released that completely eliminates such uncertainties and requires players to play logically.

When playing Minesweeper, there are cases where there may be mines in both squares, but you cannot get any additional hints. This seems to be a bug caused by Minesweeper's map generation algorithm. In the original Minesweeper, you do not step on a mine with the first click. This is because the mines are placed after the first click. As a result, some squares do not have enough hints to determine whether there is a mine or not.

Therefore, Sublevel Games developed 'Explainable Minesweeper', a minesweeper that can be solved by inference alone. In developing Explainable Minesweeper, the AI plays minesweeper from the player's perspective, and only maps that can be cleared without guesswork are included in the game.

Specifically, the game board is first randomly generated and a candidate starting position for the game is selected. The starting position candidates are 'empty square', '1', and '2'. Once the starting position has been selected, the AI is actually made to play Minesweeper. If the inference gets stuck, the starting position is changed to another candidate and the AI is made to play again, searching for a board state that can be cleared by inference alone.

You can actually play 'Explainable Minesweeper' from the following page.

'Explainable Minesweeper' can be played on either itch.io or GamePix . This time, click 'Play at ▶️gamepix.com' to play on GamePix.

First, select the size of the board. There are five sizes available: 5x5, 6x6, 7x7, 8x8, and 9x9. For now, click on the smallest size, 5x5.

Then, the minesweeper will start with some of the squares revealed as shown below.

The following squares on the left side of the board are clearly mines based on the surrounding information. Right-click to place a flag on them.

If you continue to set flags in this manner, you will see squares that are confirmed to have no mines, as shown in the red frame below.

Left-click on such a square and a number will appear.

If you continue in this manner and flag all the mines, the game will be cleared.

Click 'Next' at the top of the screen to play a new board.

If you click on a square that contains a mine or place a flag on a square that does not contain a mine, the game is over.

The most difficult '9x9' board looks like this. If you don't know where the mines are, click 'Hint' at the top of the screen. Then a hint will be displayed at the bottom of the screen. In the following case, the hint is 'Analysis shows the common area must have exactly 1 mines. Therefore, the remaining area of number 2(B) is safe. (There can only be one mine in the common area (purple squares). Therefore, the remaining squares of 2(B) are safe (there are no mines))'.

The actual gameplay is as follows:
