Logic Masters Deutschland e.V.

Rules:

• Normal sudoku rules apply.
• There are cages in the grid, digits can not repeat within cages.
• Black cages are normal killer cages, digits in these cages must sum to the value in the top left corner of the cage.
• Brown cages are hunter cages. Digits placed in hunter cages point to that box in the grid, and the cell in the same position in that box. The digits in the top left corner of a hunter cage must be pointed to by the digits in the cage; digit order does not matter.

A rule that exists for hunter cages, but is not relevant for this puzzle.

• Cages with more cells than given digits may point to any digits with the other cells.

I have gone through many drafts of the wording of these rules, and spoken to several people about them. This is the best we have so far, but are still working on finding improvements.

Rules Example

This is a solvable example.

In this the 22 cage in box 1 must have two cells pointing to two 2s. The 4 points to box 4, and the 2 is in the same cell location in that box; the 3 points to box 3 and the 2 is in the same location in that box. The 2 cage in row 4 must point to a 2 from one of the cells, the 3 points to a 2 in box 3 in the same cell location, and because there is one cell that points to a 2, the 4 can point to anything.

Solve Video

Because this is a new ruleset I have created a solve video for this puzzle where I demonstrate how the ruleset works and show how I solve this puzzle to demonstrate the logic used.

The video is in English

People who do not want any help should just ignore the video. Though if you want to see me make a mistake with my own puzzle, this is a video where I do that; I do have the correct step detailed in the video description.
