Counting remaining mines

Level: Advanced

Use the total mine count to break through a stuck position.

When partial patterns alone leave you stuck, use the global information of the 'total remaining mines.' You compare the on-screen mines-remaining counter against the cells that are still closed.

For example, if 2 mines remain and a certain region along the border must contain exactly 2 mines, then every closed cell outside that region is safe. This is especially powerful in the late game.

By tallying the minimum and maximum mines each border region needs and matching it against the total, you can reveal confirmed cells that local logic couldn't see.
