Numerično-logične uganke 8699
The grid is partially divided by black cells into compartments.
Each compartment, vertically or horizontally, must contain a straight - a set of consecutive numbers, but in any order (for example: 2-1-3-4).
Each column and each row contain the digits only once.
Clues in black cells remove that digit from the row and column, and are not part of any straight.
