I'd like for my sudoku to have five straight lines (and nothing else): - A horizontal Arrow pointing east (with a one-cell circle) - A horizontal Thermometer - A horizontal German Whispers line - A vertical German Whispers line - A vertical Zipper line Each should be as long as it is possible to make orthogonal straight lines of that variety in a sudoku. Put them wherever, just not in the cells with my signature please. I'd also like some sort of anti-chess constraint: anti-knight, anti-king, or anti-bishop (up to you, whichever works). Oh, and make sure the solution has a 3 in the corner, won't you?
