The link below is the maze that i have created out of my mine. I have been working on that level(6) for about 2+ months.
What i want to ask is, if there is a chance that the black tiles can be in the bluish areas. In previous levels, there were quite big and it was hard to miss them mining that way.
Thanks

Also, i would appreciate if someone can tell me about a better way on mining single tiles. My way is chaotic
