![]() Since this functionality is provided by the Java standard library, I cannot meaningfully speed up this part of the code. The program uses quite a bit of CPU time to capture a screenshot. The page at Minesweeper Wiki provides a decent introductory explanation of the pair strategy. It was supported by UCARE grants from the University of. ![]() The pair strategy is more complicated, and it basically considers what happens when all the unopened neighbors of a numbered cell A are also neighbors of a numbered cell B. This work was conducted in the Constraint Systems Laboratory and supervised by Berthe Y. If N = F, then all the unopened neighbors can be opened. Clear the board without detonating any mines. This board is guaranteed to be solvable by using logic alone to find all the mines. If N = F + U, then all the unopened neighbors need to be flagged. Play Minesweeper Detonate, where the goal is to detonate all the mines. There are two strategies for looking at each single cell: Suppose a cell has the number N, has F flagged neighbors, and has U unopened neighbors. The random strategy is used only if the safe options are exhausted. The first two strategies are analytical and safe. The solver algorithm has 3 different strategies: single, pair, and random. (You can copy the old Minesweeper EXE file to the newer Windows systems, of course.) It will not work for the version included with Vista and 7, nor can it be adapted easily. This program only works on the classic Windows Minesweeper (95, 98, Me, 2000, XP), with its simple graphics and lack of animations. ![]() The program will exit if you move the mouse. Source code only: MinesweeperAutosolver.javaĬomplete package: MinesweeperAutosolver.zip (source code, compiled classes, bitmaps)Īfter unzipping, run on the command line with: java MinesweeperAutosolverĮnsure that a Minesweeper window is visible on the screen before running the autosolver. This was one of my motivations for writing the solver bot, and it finally did solve the expert level. I am not sure if you are familiar with AI reasoning & logic inference - If not, you might want to have a look at the book 'Artificial Intelligence - A. With something as simple as propositional logic, you can implement a very efficient solver for minesweeper. But all this time, I was never able to solve the expert difficulty level, either because my logic was insufficient or there were too many ambiguities. Minesweeper is a good example where backtracking algorithms such as DPLL is useful. Iâve wasted my fair share of time on the classic Minesweeper game thatâs bundled with Microsoft Windows. However, with some unique skills as a programmer, I can design computer programs to play games for me with incredible efficiency. The Beginner size was changed in Windows XP from 8x8 to 9x9 to make it easier to win. Microsoft released 'Windows Minesweeper' in October 1990 before including it as part of Windows 3.1, 95, 98, ME and 2000. I donât think I have the time or talent to bring myself to the top of the rankings. This page lists minesweeper cheats, codes, bugs, scripts and solvers for Microsoft Minesweeper. Although Iâm not too bad of a gamer, for every game I played, Iâve seen plenty of players who are much better than myself. I wrote a Java program that plays the Windows Minesweeper game automatically â it reads the screen, computes the moves to make, and performs the mouse movements, all at superhuman speed and accuracy.Įveryone has been exposed to video games at some point in their lives. You can either try the square marked with '?', or make your own guess.Conceding that Iâm not going to be the fastest or best gamer, I instead chose to exercise my programming skills. For your next move, you will have to make a guess. It will then mark one square that has the highest chance of being safe with a green '?' symbol. If the solver cannot find a definite solution, it will calculate for all the remaining squares the probability of being safe.If a mine is found it will be marked with a red flag.If a safe square is found it will be marked on the board with a green flag.Each cell is a boolean state: mine or clear. How does it work A minesweeper board is essentially a set of logical constraints. It achieves this through advanced combinatorial and probability analysis. Click on 'Find next move' or 'Find all moves' and the solver will check for possible moves It's a minesweeper solver It can solve any board, with any topology, and exactly compute every cell's chance of being a mine.Then click the square on the board to set it. Then, fill the board with numbers for the squares you know.First, select the required board size and the number of mines.
