Minesweeper Openings: Where to Click First
Every Minesweeper guide tells you how to finish a board — patterns, counting, probability. Almost none tell you how to start one. Yet the opening is the one moment where you have no numbers to reason from, so the only edge available is choosing where that first blind click lands. It turns out the choice matters, and the logic behind it is simple.
Your first click is always safe — use that
On our Minesweeper, as on most modern versions, the board is only generated after your first click, and it's generated so that your click never lands on a mine. That's a free, guaranteed reveal anywhere on the board. The question is where it buys you the most.
What you're hoping for is not just a safe cell but a zero — a cell with no adjacent mines. Zeros are the jackpot of the opening: the game auto-reveals all their neighbours, and any of those that are also zeros cascade in turn, flooding open a whole region and handing you a border of numbers to work with. A first click that reveals a lonely "3" is safe but nearly useless; a first click that hits a zero can open a third of the board.
Corners open more often — centers open bigger
A cell is a zero only if every one of its neighbours is mine-free. That's where geometry comes in: a corner cell has just 3 neighbours, an edge cell has 5, and a central cell has 8. Fewer neighbours means fewer chances for a mine to sit next to you — so corners are the most likely spots to produce a zero, edges next, centers last.
There is a counterweight: when a central click does open, the flood can spread in all directions, and the numbers on its frontier constrain more covered cells — central openings carry more information. So the practical advice splits by difficulty. On Expert (99 mines), where any opening at all is precious, start in a corner; if it doesn't cascade, click the opposite corner next. On Beginner and Intermediate, mine density is low enough that openings come easily — clicking near the center is fine and gives you a richer frontier to work from.
The flood stops. Now what?
The moment your opening cascades, resist the urge to click somewhere else at random. The frontier of the flood — that line of numbers wrapped around the revealed region — almost always contains forced moves, and they cost nothing to collect.
- covered cell
- revealed number
- safe
- mine
Work the frontier in this order. First, look for numbers whose covered neighbours are all accounted for — every remaining neighbour of a satisfied number is a free safe click. Second, look for overlapping numbers where subtraction forces a mine or a safe cell, as in the diagram above. Third, scan for ready-made shapes like the 1-2-1. Only when the frontier is truly exhausted should you open a new region — and when you must, apply the same opening logic again: pick a corner or edge far from the mess you already know about.
The opening in one sentence
Click a corner (or center on easy boards), let the flood hand you a frontier, and squeeze that frontier dry before you ever guess again — from there on it's standard technique, and on the rare board that forces a true guess, guess smart.
