Questions tagged [logic-grid]
Logic grid puzzles, first produced by Lewis Carroll, are puzzles in which correspondences must be drawn between multiple ways of describing the same list of objects, using a given set of clues about these correspondences. Such puzzles can be solved using a grid, but for pre-existing grids whose elements must be filled using logic, use the [grid-deduction] tag instead.
