Logic Masters Deutschland e.V.

This is the first puzzle I post here, I chose one with an original and innovative set of rules, I hope you enjoy solving it.

Normal sudoku rules apply.

There are 2 special sets of cells to be discovered by the solver, each consisting of one cell in each 3x3 box. Each set contains every digit from 1 to 9.

In both sets the cells are chained in a single loop with the following relation : if a cell is at position P within its box and has value V then the next cell is in box P at position V (positions are numbered left to right then top to bottom). For example, if there is an 8 in the top middle cell of a box, it points at the 8th cell of the top middle box.

Digits within a cage sum to the number in its topmost corner and cannot repeat. Additionally, if a cage is entirely contained in a box, then the cells from all special sets in that box will also sum to that number.
