3D-PROBLEMS SPIDER AND FLY RUBIKS CUBE
Here is an interactive version of the famous Rubik cube. You can twist or rotate the cube by pointing and dragging on the cube with your mouse.
The objective is to have only one colour on each side, after scrambling it.
Press s on the keyboard to scramble and r to restore (while positioning the mouse cursor somewhere in the cube – and note that s and r are case-sensitive!).
