Minesweeper

💣 Minesweeper: The Foundation of Algorithmic Logic

Minesweeper is arguably the most important logic puzzle in the history of computer gaming. It is not a game of luck; it is a rigorous exercise in deductive reasoning and binary state analysis. In 2026, it remains a primary tool for training cognitive discipline. The goal is simple: clear a rectangular board containing hidden "mines" or bombs without detonating any of them, with help from clues about the number of neighboring mines in each field.

This HTML5 iteration preserves the pure, distraction-free interface of the 1990s classic while adding modern responsiveness. It strips away the graphics to focus entirely on the logic grid.

🧠 Cognitive Training: The "If-Then" Loop

Minesweeper is essentially a visual programming language for the brain:

• Deduction: "If this square is a '1' and touches only one covered square, that covered square must be a mine." This is the fundamental unit of logic.
• Exclusion: "If this square is a mine, then the neighbor cannot be a mine." This trains negation logic.
• Probability Assessment: In the famous "50/50" scenarios where logic fails, players must calculate the statistical probability of a mine location based on the density of the remaining board.

🎮 Mechanics & Techniques

The game operates on a fixed grid system:

• The Grid: Each cell has 8 neighbors (vertical, horizontal, diagonal). The number on a cell indicates exactly how many mines are in those 8 neighbors.
• Chording: This is an advanced mechanic. If an uncovered cell with a number has the correct number of flags around it, clicking the number itself (or clicking both mouse buttons) reveals all remaining neighbors instantly. This increases speed by 300%.
• First Click Safety: The modern algorithm ensures the first click is never a mine, and usually opens a "zero" area to give the player a starting foothold.

🏆 Solving Strategies

1. The "1-2-1" Pattern

Recognizing patterns is key. If you see a 1-2-1 sequence against a straight wall of covered tiles, the two 1s always have mines next to them, and the 2 does not. Memorizing these standard patterns reduces mental fatigue.

2. Working from the Edges

Start solving from the corners or edges. Cells in the middle of the board have 8 unknown neighbors, while corner cells only have 3. Reducing the variables makes the logic easier to parse.

🛡️ Technical & History

A timeless piece of software:

• Load Time: Instant. The code is incredibly lightweight, requiring virtually no resources.
• Input: Supports right-click to flag (on desktop) and long-press to flag (on touchscreens).
