Puzzle (Brain Teaser) game

Minesweeper

Minesweeper is a classic puzzle and brain teaser game built around careful clue reading. Reveal safe squares, use the number clues to reason about nearby hidden mines, place flags when a square is risky, and clear the board without guessing too quickly.

A puzzle game about reading clues

Minesweeper fits the Puzzle (Brain Teaser) section because every move depends on evidence. A number tells how many hidden mines touch that square. If a revealed 1 already has one flagged neighbor, the other nearby covered squares are safe. If a revealed 3 touches exactly three covered squares, those covered squares are likely mines.

How to play Minesweeper

Choose a difficulty, then tap or click a covered square to reveal it. Safe empty areas open automatically. Numbered squares show how many mines are touching that square horizontally, vertically, or diagonally. Use flag mode to mark squares that you believe contain mines. The goal is to reveal every safe square while leaving the mines covered.

Why it works as a brain teaser

Good Minesweeper play is not about speed at first. It is about comparing several clues at the same time. Players look for squares that are forced by the numbers, make a flag only when the clue supports it, and avoid opening random squares until there are no clear deductions left. That kind of patient reasoning is useful in math, logic, coding, and everyday problem solving.

Built for desktop and touch screens

This version supports normal clicking, right-click flagging, long-press flagging on touch screens, and a flag mode button for phones and tablets. The board resizes inside the game frame so the puzzle remains playable from small practice rounds to larger advanced boards.
