This puzzle type I created for "Contest for best logic innovation"
Place some mines in each diagram so that the numbers inside the grid indicate the amount of mines in the neighboring cells. Also draw a loop into the diagram, which does not touch or cross itself. A digit in a cell indicates the amount of its edges used by the loop. All the mines should be inside the loop. Blackened cells cannot contain any mine but its sides can be part of the loop. Some of the mines or part of the loop may be already given.
