Logic Masters Deutschland e.V.

There aren't enough puzzles taking advantage of products as a clue type, so here's a few I found, and one I made.

• Production Line by starwarigami
• Which is Which and Which is Which, Again by DJV - killer cages are either sums or products
• Region Sum/Product Lines by Migu
• X-Products by bigger - pure x-products

Did I miss your favorite? Suggest it below in the comments! And here's my addition to the collection:

The Rules:

1. Normal sudoku rules apply
2. [X-Sums/X-Products] Numbers on the outside of the grid are either the sum or product of the first X cells seen from the direction of the clue where X is the digit in the cell next to the clue. The solver must determine which clues represent sums and which ones are products.
