Logic Masters Deutschland e.V.

Normal 9x9 Sudoku rules apply.
Digits connected by a white Kropki Dot are consecutive.
Digits on a purple Renban line form a set of consecutive digits in any order and also work as indexers forming a connection with renban constraints:
Each digit on such line will point towards its row and column.
That digit and the targeting cell are in a white kropki dot relationship.
(E.g. A 2 on a line in r9c6 will indicate that it is consecutive with r2c6 and r9c2 )
The purple circle is a 1 cell ranban line meaning it only has the indexing property described before.
