LEV  PUZ 
     

Kurotto literally means "black units" and is a logical puzzle published by Nikoli. The task consists of a grid with circles in some cells. A circle can contain a number or not. The task is to blacken cells according to the following rules:

  • Make cells black so that each circled digit represents the total number of black cells in connected groups that share a border with that circled digit.
  • Cells with circles cannot be black.
  • Cells with circles without a number: you don't know the total of number of cells in connected groups.
