Apprentice Minesweeper: 12×12, 22 mines

A size the classic set lacks: between Beginner 9×9 and Intermediate 16×16. 22 mines on 144 cells, about 15%: a little denser than Beginner and with more room.

Here you meet the first real patterns. About half of these boards need two numbers compared at least once, most often 1-1 or 1-2: when one number alone says nothing, look at its neighbour. If you are stuck, the hint shows the step and highlights the numbers it comes from.
