Outward Chain #1 diagram

Explanation

This small area might be able to have its amount of mines determined, let’s try it out.

Red cells contain one mine

Orange cells contain two mines

Yellow cells contain one mine

Blue cells contain one mine

The purple cells contain 0,1,2 mines.

Purple cannot have 0 mines, as that would end up in the 3 having 4 mines.

Thus purple must have 1 or 2 mines, giving the total area 6 or 7 mines, let’s try minecount in both cases.

After some logic...

(6), Red cells contain three mines

Orange cells contain one mine

Yellow cells contain one mine

Green cells contain one mine

There are 6 mines, so the lime crossed cells are safe

After some logic...

(7), Red cells contain one mine

Orange cells contain two mines

Yellow cells contain one mine

Green cells contain one mine

There are 7 mines, so the red crossed cells are the only place where the last mines go

Seems to be the only outward chain documented, box logic not included
