Logic Masters Deutschland e.V.

For another of Scojo's prompts, this time using Half-Modifier, Region Sum Lines and Clones.

• Normal sudoku rules apply.
• Shade nine cells so there is exactly one shaded cell in each row, column and 3x3 region. Shaded cells cannot contain repeated digits. If D is a digit in a shaded cell the value of that shaded cell is D/2. Values of non-shaded cells are the same as the digit they contain.
• Region borders split blue lines into connected components with the same value sum. That same sum may differ between different lines.
• Cages of the same shape and orientation are clones: their contents are equal in values and their placement. Digits and/or values may repeat in cages.
