How Minesweeper works
The expert board runs 22 by 16 with 80 mines, a density around 23 percent. At that concentration cascades are rare, most of the board is worked one square at a time, and you will face several positions with no logical answer.
Efficiency is what separates good expert players from slow ones. Flagging every mine you identify is far too slow at this size; flag only where a flag unlocks a counting rule and leave everything else covered. Working multiple fronts in parallel rather than exhausting one region also saves substantial time.
Five to twelve minutes is typical. Losing roughly a third of expert boards to a forced guess is normal even for strong players, because at this density the endgame frequently comes down to a genuine coin flip.

How to get faster on expert
- Flag almost nothing. At this size flagging every mine you identify is far too slow. Place a flag only where it immediately unlocks a counting rule, and leave the rest covered.
- Open in a corner. Corners give the highest chance of a usable cascade and the fewest unknown neighbours per number. A central opening on a board this dense frequently leaves you with nothing to work from.
- Work the perimeter inward. Edge squares have five neighbours instead of eight, so edge numbers constrain far more tightly. Most expert boards unravel from the outside.
- Guess early rather than late. If a region has no logical answer, take the guess while the rest of the board is still intact. Guessing at the end means losing several minutes of correct work instead of a few seconds.
- Use the remaining mine counter in the endgame. With 80 mines placed, the global count often resolves positions that are locally ambiguous, and it is the technique most players neglect entirely.
Frequently asked questions
How big is the expert Minesweeper board?
22 × 16 with 80 mines, a density of about 23%.
What is a good expert Minesweeper time?
Around 5 – 12 minutes is typical for this board. Consistently beating the lower end of that range means your pattern recognition is doing the work rather than counting.
Will I be forced to guess on expert?
Sometimes, yes. At this mine density the endgame can present two squares with identical information, and no amount of logic separates them.
Why do I lose so many expert boards to guessing?
Because at around 23 percent density some positions genuinely have no logical answer. Losing roughly a third of expert boards to a forced guess is normal even for strong players, and it is not a sign you played badly.
Should I flag mines on expert?
Only where a flag lets you apply a counting rule. Flagging all 80 mines costs 80 clicks, which is a large fraction of a good expert time for no additional information.
What is a good expert Minesweeper time?
Five to twelve minutes is typical. Consistently finishing under three minutes is strong, and that comes from efficiency (minimal flagging, parallel fronts, early guessing) rather than from faster clicking.
