Speed & Strategy

Getting faster at Minesweeper is not about clicking harder. It is about removing wasted actions: chording instead of opening cells one at a time, skipping flags that carry no information, keeping mouse travel short, and abandoning a bad board early rather than grinding it out. These guides cover the technique and the measurement, including 3BV and 3BV/s, the metrics competitive players use instead of raw finishing time.

The numbers speedrunners actually track

3BV
The minimum number of left clicks needed to clear a board with perfect play. Each opening counts as one click, plus every safe cell outside an opening.
3BV/s
3BV divided by your finishing time. This is what competitive players compare instead of raw seconds, because it removes the luck of the board.
Efficiency
3BV divided by the clicks you actually used, as a percentage. Exactly 3BV clicks is 100%; chording can push you above it.
Chording
Pressing both mouse buttons on a numbered cell whose mines are already flagged, opening every remaining neighbor at once. One chord can replace eight clicks.
Flagless
Clearing without placing flags at all. A flag costs a click and carries no information the numbers do not, so dropping them removes up to 99 clicks from an Expert board.

Once you have read enough, put it to work: measure a board with the 3BV calculator, check where you stand with Is My Time Good?, then set a ranked time on Expert.
