The next round of the Puzzle GP takes place next weekend, with the Dutch round authored by Bram de Laat. The instructions are out; it turns out Maxi Loop is one of the types (see Puzzle 91 and Puzzle 109), so we’ve got that done. One of the less familiar types is Greater Wall, compare Bram’s set for the Polish championships. The presentation has been much improved, with explicit placeholders. Here’s one.

Rules Shade some cells to form a wall that is connected by edge and doesn’t contain any 2×2-square. Where given, clues outside indicate all connected blocks of shaded cells in the corresponding row or column, in the correct order. Relations between two placeholders apply to the lengths of the corresponding blocks.
