PentaStar Pocket Prism
A round version of this puzzle has been built and has been called
Star Puck. The much shallower cut of the Pentagonal Domino Prism
seems to make for a much easier puzzle, because the additional
side faces provide a lot of extra information.
Therefore I decided to call this puzzle a PentaStar Pocket Prism.
Java Applet Instructions
-
The Green Flag resets the puzzle.
-
Pressing the Spacebar scrambles the puzzle.
-
If you click on any of the five central triangles pointing
outward from the central pentagon, this cubelet and the two adjacent ones
are turned over by 180 degrees.
-
Pressing a turns the upper layer of the prism by 72 degrees
clockwise (as seen from above). The same can be achieved by clicking on the
leftmost face of the layer.
-
Pressing y or z turns the upper layer of the prism by
72 degrees counterclockwise (as seen from above).
The same can be achieved by clicking on the
rightmost face of the layer.
-
Pressing s turns the lower layer of the prism by 72 degrees
clockwise (as seen from above). The same can be achieved by clicking on the
leftmost face of the layer.
-
Pressing x turns the lower layer of the prism by
72 degrees counterclockwise (as seen from above).
The same can be achieved by clicking on the
rightmost face of the layer.
-
Pressing q flips the entire prism over by 180 degrees
in the direction left --> right. The same can be achieved by
clicking on the top of the central pentagon.
-
To solve the prism, you have to get the pentagram on the
top side yellow, the rest of the top side white,
the left side green, the front side blue and the right side red.
(The orange back left face, purple back right face, and the white pentagram
and yellow rim on the bottom are invisible.)

When you have solved the prism, your time taken is displayed
for some seconds.
