Logic Masters Deutschland e.V.

Rules:

Quattroquadri: Normal Quattroquadri rules apply for the 6x6 grid. Place a digit from 1-9 in each empty cell in the grid such that digits do not repeat in any row, column, or 3x3 box.

Dynamic Fog:The grid is covered in fog. Placing a correct digit in a cell lifts fog from that cell and possibly other clues outside the grid.

Toroidal X-Sums: Clues outside the grid indicate the sum of the first X digits in the corresponding direction, where X is the digit placed in the first cell in that direction. Rows and columns are toroidal, so if X is bigger than 6, the next cell after the 6th cell will be the first cell in the row/column again.
