Notes on this puzzle
Mine Finder #5310 hides 99 mines in a 30×16 field of 480 cells, a density of 20.6%. Some cells only give way when two neighbouring numbers are compared.
The board starts with 37 cells already uncovered, 10% of the safe ground, so the first deduction is waiting for you. Under the cover, 73 safe cells touch no mine at all, 123 show a 1 and 113 show a 2; 72 cells carry 3 or more, and the highest number in the field is 5. 18 of the mines lie along the border of the field.
Where to beginKeep an eye on the mine counter; on this field the final pocket is often settled by the total.
