4D Maze
How to play
Drag the spherical slider along the tubes to reach the cubical goal.
Ana and kata
The English language has always had words describing the first three dimensions.
In the 1880s Charles Hinton introduced the Greek words ana and kata
to refer to the positive and negative directions in the fourth dimension:
1st |
dimension: |
backward |
/ |
forward |
2nd |
dimension: |
left |
/ |
right |
3rd |
dimension: |
down |
/ |
up |
4th |
dimension: |
kata |
/ |
ana |
What the colors mean
4D Maze represents each point's first three dimensions in the usual way,
while using color to represent the fourth dimension.
The kata-most points are colored red,
the ana-most points are colored violet,
and all intermediate points are colored
with the intermediate colors of the rainbow (red, orange, yellow, green, blue, violet).

A tube that runs directly into the fourth dimension — perpendicular
to our usual 3D space — looks to our eyes like a single point
that runs through a spectrum of colors.

Superimposed points
Tubes that sit directly “over” each other in the fourth dimension
should, in principle, appear perfectly superimposed in the maze,
differing only in their color. However, perfectly superimposed tubes
would be impossible to see clearly, so 4D Maze nudges them slightly apart
(see first image in previous section).
Similarly, a “rainbow tube” running straight into the fourth dimension
(second image in previous section) should, in principle,
appear as a single point in the maze, but again 4D Maze nudges
its endpoints slightly apart for easier visibility.
4D connections
While solving a maze, you can move the slider from a red tube
to a violet tube only if a rainbow tube connects them (left image below).
Otherwise you cannot move the slider from the red tube
to the violet tube because they sit far apart in 4D space,
with no path connecting them (right image below).
Visually, the difference can be subtle, so look carefully
for that rainbow connecting tube!
