Cube Crisis (hard)
This is a 3D version of a link maze in which you alternate between matching shape and colour.
Start at the pink sphere in the top back corner, and find a route to the blue sphere in the bottom front corner.
For your first step you can move horizontally or vertically (but not diagonally) to another symbol with the same shape, so the only possible move is from the pink sphere at the starting position to the blue sphere to its left.
For your next step you must move horizontally or vertically to a symbol with the same colour. So now the only possible move is to the blue cross vertically above.
Continue in this way, alternating between matching shapes and matching colours, until you find a route to the goal.
To solve this maze you'll need to use a pencil and paper; you can't solve it interactively.
Drag to rotate the maze.
