Logic Masters Deutschland e.V.

Fillmat: Divide the grid into 1xN rectangular regions of 1 to 4 cells. Regions of the same size cannot touch orthogonally, and region borders cannot form any 4-way intersections.

Nuri-Maze: Shade some cells such that each region is fully shaded or fully unshaded, and the unshaded cells form a single orthogonally connected area with no loops. No 2x2 area can be fully shaded or fully unshaded.
All clues must be unshaded. There is exactly one path through unshaded cells from the S (start) to the G (goal) without backtracking; circles must lie on this path, and triangles must not.
