A number from the range 1~N must be entered in each white cell so that each number occurs exactly once in each row and each column. (N = number of white cells in the rows/columns).
The sum of the numbers in strips of horizontally or vertically neighbouring white cells is given (like the word definitions in a crossword puzzle).
If there is a circle between two cells, the difference between the numbers in these cells must be exactly 1.
Otherwise, the difference between the numbers in the two cells must not be 1.
