Place the digits 1-7 exactly once each in every row, column, and region.

Regions are identified by bold outlines. Some cells belong to 2 regions at once, in which case the outline of those two regions passes through the cell instead of being on the border of 2 cells.

Digits on an arrow sum to the digit inside of the attached circle.
