MineSweeper

Step 1 — Choose Your Difficulty Select the board size and mine count that matches your skill level: Beginner — 9×9 grid with 10 mines. The perfect starting point to learn the rules and develop core strategies Intermediate — 16×16 grid with 40 mines. A bigger board with more complex patterns that rewards faster and sharper thinking Expert — 30×16 grid with 99 mines. The ultimate challenge — demanding pattern recognition, edge logic, and nerves of steel Step 2 — Make Your First Click (Always Safe) Click any square to begin. Your first click is always guaranteed to be safe — mines are placed after your first move, so you will never blow up on the opening click. Most first clicks open up a large area of the board automatically, giving you numbered clues to start reasoning from. Step 3 — Read the Numbers Every number revealed on the board tells you how many mines are hidden in the eight squares directly surrounding it — including diagonals. This is the core logic of the entire game: A 1 means exactly one of its neighboring squares contains a mine A 2 means two of its neighbors are mines A 3 means three neighbors are mines — and so on Use these numbers together to deduce exactly which squares are safe and which are dangerous. Step 4 — Flag Suspected Mines When you are confident a square contains a mine, right-click it (or long-press on mobile) to place a flag. Flagging mines serves two purposes: it prevents you from accidentally clicking that square later, and it helps you visually track which mines are accounted for as you work through the board. The mine counter in the corner shows how many unflagged mines remain. Step 5 — Reveal Safe Squares Left-click any square you are certain is safe to reveal it. If your deduction is correct, the square opens and shows either a number (telling you about neighboring mines) or a blank space (meaning no mines are nearby), which automatically opens all adjacent safe squares in a chain reaction. Step 6 — Clear the Entire Board to Win The game is won when every square that does not contain a mine has been revealed. You do not need to flag every mine to win — just uncover all the safe squares. The timer tracks your completion time, giving you a personal record to beat with every game. Step 7 — Avoid the Mines Click a mine and the game ends immediately — all mine locations are revealed on the board. No undos. Start a fresh game and apply what you learned from the layout. Controls Desktop: Left-click to reveal a square, right-click to place or remove a flag Mobile: Tap to reveal, long-press to flag Tips to Clear the Board Faster Always start by scanning for squares whose number equals the exact count of remaining covered neighbors — those neighbors are guaranteed mines, so flag them immediately When a numbered square already has all its mines flagged, left-click it to safely reveal all remaining neighbors at once — this is called chording and it dramatically speeds up your clears Never guess when logic is still available — work outward from numbered clues and only consider probability when the board offers no certain deductions On Beginner, practice memorizing the most common number patterns — a 1-2-1 pattern along an edge is one of the most reliable indicators of mine placement in the game
