Problem solving game, Qubrix, requires excellent sense of orientation in 3D space and can be used as a tool to train or test that sense. The game exploits advantage of 3D software technology to present a problem similar to the one found in Rubik's Cube. Basic level consists of a set of nine cubes enclosed in a frame, each cube is geared to adjacents so when the player rotates chosen one particular near by cubes are rotating, also. Cubes are texturized with six different images, a slice for each side of the cube. At the beginning of the game, in a random manner, enclosing frame is also textured with one of those images and cubes were given a random orientation. Point of the game is to put required image together, as fast as possible, by rotating cubes. Qubrix is based on ISO standard Web3D technology and uses Bitmanagement's Contact, Web3D player (plug-in), that makes it available for various OS/Browser platforms, including mobile. Game can be embeded into a Web page or used inside a virtual world, as an addition for 3D chat places. Qubrix http://www.vrinternal.com/qubrix/index.html
