Notes on this puzzle
Mine Finder #5102 hides 10 mines in a 9×9 field of 81 cells, a density of 12.3%. Every safe cell here can be decided by looking at one number at a time.
The board starts with 48 cells already uncovered, 68% of the safe ground, so the first deduction is waiting for you. Under the cover, 30 safe cells touch no mine at all, 29 show a 1 and 8 show a 2; 4 cells carry 3 or more, and the highest number in the field is 3. 5 of the mines lie along the border of the field. Corners hold 2 of them; a corner cell has only three neighbours.
Where to beginFlag only when you are sure; then use the chord tap on satisfied numbers to clear ground quickly.
