About this game

Minesweeper is a classic deduction puzzle bundled with Windows for decades and still loved worldwide. You face a grid of hidden cells; some contain mines. Revealing a safe cell shows a number telling how many mines touch that cell orthogonally and diagonally. You win by opening every non-mine cell. Flag cells you believe contain mines. One wrong click on a mine ends the game. The blend of logic, probability, and tension makes Minesweeper timeless. PuzlPlay offers free online Minesweeper with beginner to master board sizes, timers, win tracking, and the familiar Windows-style feel in your browser.

Steps to play

  1. 1. Reveal cells — Tap a hidden cell to reveal it. If it is a mine, you lose. Safe empty cells open a whole region automatically. The first click is always safe.
  2. 2. Number clues — A revealed number is the count of mines in the eight surrounding cells. Use that count with flags to deduce which neighbors are mines or safe.
  3. 3. Flag mines — Switch to Flag mode to mark suspected mines (and Maybe/? if available). Flag carefully — wrong flags block chord clears. Switch back to Reveal to continue opening cells.
  4. 4. Chord & peek — On numbered cells, a normal tap chords (opens neighbors when flags match the number). Double-tap a number to peek adjacent tiles when peek charges remain — mines and safe cells flash briefly.

Tips & Strategies

When a revealed 1 touches exactly one hidden cell, that cell must be a mine—flag it. A 0 clears its neighbors safely; use these openings to expand. Count mines around larger numbers before clicking uncertain cells. If two patterns overlap, solve the overlap first. When guessing is unavoidable, pick the cell with the lowest mine probability—usually an edge or corner away from dense numbers. Chord-click (clicking a satisfied number with correct flags) speeds clearing on desktop. Finish faster by solving obvious flags first, then work inward.
