Now in 3D

The tag can bring a nice twist to a variety of puzzle types. We've seen paper folding, grid deduction, crosswords, mazes and even pencil-and-paper game puzzles use the extra dimension to great effect. While presenting 3D things in a 2D environment brings some challenges to both setters and solvers, the added dimension offers a nice opportunity to produce some real mind benders when done right. Creativity is encouraged – the only requirement here is that the puzzle somehow make use of three-dimensional space.
