The G3ODE is a mind-bending software-based puzzle with a 3D graphical interface.
The puzzle is a polyhedron with tiles covering all facets but one. Each tile has two distinctively coloured sides. Any of the 3 tiles adjacent to the empty facet can be flipped into that space.
In colour-only mode, the puzzle is solved when all tiles are flipped such that the surface of the puzzle is all one colour. In decal mode, similar to a jigsaw, the puzzle is solved when all tiles are arranged such that the image is reconstituted on the surface of the puzzle.
Nothing. The G3ODE software is offered to you absolutely free of charge. Get a copy of the latest version from the download page.
Patience and a little deep thought should see you through.
The G3ODE puzzle software was developed by Nicholas Quaine in 2007. It sprang from a 1994 brainstorm between himself and Dominic Jaeger, motivated by a desire to find the next Rubik's Cube. It was originally envisaged as a physical hand-held puzzle, but after many years in the difficult-to-build folder, a software-based puzzle was created instead.
