Notes on this puzzle
10 mines, 71 safe cells and one 9×9 field: that is Mine Finder #5103. Every safe cell here can be decided by looking at one number at a time.
The board starts with 38 cells already uncovered, 54% of the safe ground, so the first deduction is waiting for you. Under the cover, 29 safe cells touch no mine at all, 32 show a 1 and 6 show a 2; 4 cells carry 3 or more, and the highest number in the field is 4. 5 of the mines lie along the border of the field.
Where to beginFlag only when you are sure; then use the chord tap on satisfied numbers to clear ground quickly.
