Logic Masters Deutschland e.V.

This may be a bit harder than average, maybe 3.5-4.

Standard sudoku rules apply: each row, column, and 3x3 cell must contain all the digits from 1 to 9.

Digits in cages must sum to the small number in the upper left corner of the cage, and must not repeat within the cage.

The blue lines are Equal-sum Entropic lines: three consecutive cells on a line must have a high digit (789), a medium digit (456), and a low digit (123). Additionally, the sum of the digits on a line segment within a box is the same for each box the line passes through. If a line enters a box more than once, each segment within the box is considered separately.

The dark blue line is separate from the light blue line.
