How do you play Minesweeper Pure?

1
Tap any cell to start: Your first click triggers an opening cascade of safe tiles.
2
Read the revealed numbers: A number tells you how many mines touch that specific cell.
3
Place flags on obvious mines: If a 1 touches only one closed tile, that tile is a mine.
4
Chord to open safe neighbors: Click satisfied numbers to quickly uncover safe neighboring squares.
5
Clear all safe squares: You win when every non-mine tile on the board is opened.

Beginner Tips for Success

  • •Look for 1s in corners touching only one closed cell to find guaranteed mines.
  • •Use chording on satisfied numbers to open safe neighbors quickly.
  • •Do not guess prematurely; search the entire board for logical clues first.
  • •Monitor the remaining mine counter to assist endgame deductions.
  • •Flag suspected mines early to prevent accidental clicks.
  • •Compare overlapping neighbor sets between adjacent numbers.

Key Strategies & Advanced Techniques

1. The 1-2-1 Flat Wall Pattern

Definition: When numbers 1-2-1 appear in a straight line along an unrevealed flat wall.

Example: Mines are located under both 1s, and the cell touching the central 2 is 100% safe.

When to use: Whenever you encounter a straight boundary with a 1-2-1 sequence.
2. The 1-2-2-1 Boundary Sequence

Definition: A sequence of four numbers along a wall where outer numbers are 1s and inner numbers are 2s.

Example: Mines are located under both 2s, while the outer flanking cells are provably safe.

When to use: On Intermediate and Expert boards with long flat walls.
3. Corner 1 Deduction

Definition: A 1 in an outer corner touching exactly one unrevealed cell.

Example: If a corner cell has the number 1 and only one diagonal unrevealed neighbor, that neighbor is a mine.

When to use: During the opening phase after the first cascade.

A Short History of the Game

Minesweeper roots trace to early 1960s mainframe games like Cube and Relentless Logic. Curt Johnson and Robert Donner created the canonical version in [VERIFY: 1989], which was officially bundled into desktop operating systems in [VERIFY: 1990]. It remains one of the most widely played deductive logic puzzles in computing history.

Frequently Asked Questions

Can you lose on your first click in Atelier Minesweeper?
No. Atelier Minesweeper guarantees a 100% safe first click by dynamically repositioning mines away from the clicked cell and its eight neighbors before opening.
What is chording in Minesweeper?
Chording means clicking on an already revealed number whose required flags have been placed. This instantly reveals all remaining unflagged adjacent squares.
Is Minesweeper NP-complete?
Yes. Richard Kaye proved in [VERIFY: 2000] that determining whether a Minesweeper board has a valid mine configuration is mathematically NP-complete.
