Knowing the rules and the classic patterns makes you a competent minesweeper player. Strategy is what turns competence into wins: where to open, when to flag, how to handle uncertainty, and how to close out a game without a fatal guess. This guide covers the full arc of a game, from first click to last cell.

1. Open in the Center

Your first click is always safe, so use it where it buys the most information. A click near the center of the board has eight directions to cascade into and produces numbers with the richest neighborhoods. Corner and edge openings reveal less and leave you working with thinner information.

If the opening yields only one or two numbers, click again in a nearby unrevealed region rather than grinding deductions from a single "1". Early game, expanding territory beats squeezing every drop of logic from a poor start.

2. Flag with Discipline

A flag is a commitment. Follow three rules:

• Only flag proven mines. A flag placed on a hunch poisons every deduction you build on top of it. If a number contradicts your flags, suspect the flags first.
• Re-read after every flag. Each flag effectively reduces the numbers around it (see reduction). New safe cells appear constantly.
• Flag less as you improve. Speed players flag only what enables a chord — or skip flags entirely. Fewer clicks, fewer errors.

3. Learn Chording

Chording means revealing all remaining neighbors of a number at once when its flag count already matches the number — on desktop, click (or press both buttons on) a satisfied number. It turns "flag twice, click six times" into a single action and is the foundation of fast times. In Bean Boom, a correctly flagged number lets you chord for instant clears.

4. Work the Walls

Walls and edges are where named patterns concentrate: 1-1, 1-2, 1-2-1, and 1-2-2-1 all live against walls. Mid-board clusters with high numbers are information-rich but slow to resolve. A practical rhythm: expand in the open, then clean the walls with patterns.

5. Defer Uncertainty

When you hit a region that offers no forced conclusion, do not guess immediately. Mark it mentally, move elsewhere, and continue extracting guaranteed cells. Two things happen when you defer:

1. New reveals around the region often resolve it without a guess.
2. You reach the endgame holding extra information — the mine counter — that shrinks or eliminates the guess.

6. Guess Smart When You Must

Classic minesweeper cannot be solved by pure logic 100% of the time. When a guess is unavoidable, improve the odds:

• Prefer corners of unknown regions that satisfy multiple numbers at once — a wrong guess still yields information.
• Compute rough probabilities: a cell that must be a mine in 7 of 10 remaining arrangements is 70% a mine — but the cell that is safe in 7 of 10 is where you should click.
• Take forced guesses early if losing costs little time, and late if you are protecting a good board. Decide based on how much you have invested.

7. Count the Endgame

The final phase is won with arithmetic. If the mine counter reads one and two unresolved regions remain, only one region can hold the mine. If a region requires a mine to satisfy its numbers, every cell outside it is instantly safe. Strong players often save an easy region for last precisely to use the counter this way.

8. Build a Routine

Consistent play beats brilliance. A routine that works: center opening → cascade outward → clean walls with patterns → reduce numbers after every flag → defer unresolved regions → close with counter arithmetic. Run the routine on Bean Boom's Easy board until it is automatic, then carry it to Medium and Hard.
