Replace the letters by digits 0-9. Same letters mean same digits, different letters mean different digits.
Then fill in black fields and digits 1-6 into the diagram. No digit may repeat in one row or column.
The numbers outside the grid give the sum of connected digits in correct order.
Solution code: Columns 3 and 6, S for blackened fields.
