## Oskar's four dimensional maze

Consider this ... what would a four-dimensional maze look like if prototyped as a three-dimensional mechanical puzzle or rendered as a two-dimensional virtual puzzle? Well, here is the answer. Can you manouvre the four-dimensional runner to its four-dimensional goal?

The four red runners must reach the blue targets. Notice that the four runners are coupled and always form a rectangle. A move is only possible if the coupled runners can move simultaneously. Learn the operation by first playing the 'trainer' challenge a few times.

**Sample puzzle**

#### Aim

Manouvre the red runners onto the blue target.

#### Controls

Use **select maze** to select a puzzle

Use **reset** to restart the current puzzle

#### Movement

Move a pair of red dots by dragging one with the mouse

Or use tab and cursor keys

The photo on the right shows a mechanical realisation of Oskar's
4D Maze. The red disc contains two mazes, there is a second disc
on the reverse that contains another two mazes. The 'runners'
are the clear spheres, there are two more on the reverse. The
runners are locked in pairs (back and front) and also locked
to the green and yellow semi-circles which can be slid apart
in a controlled manner to effect the *always form a rectangle*
rule. The photo here illustrates the start position, the goal
is to solve all four mazes simultaneously so the puzzle comes
to pieces.

The illustrated puzzle is an implementation of maze '4x4x4x4' (see applet) but translated into three-dimensions as opposed to four. Puzzle design is by Oskar and manufacture is by George Miller.
