Black Hole Rules
The object of the game is to locate the black holes in the playing field.
In order to locate them you are allowed to shoot rays of light into the
field. If the ray does not get near, or enter a hole, then it exits the
field directly opposite of where it entered. Otherwise, a black hole can
influence the path of the ray in one of three ways.
- Deflection. If a ray would pass adjacent to a hole it is deflected 90
degrees away from the hole just prior to reaching it. Deflections are
indicated by a matched set of markers (one at entry and exit)
- Absorption. If the ray runs directly into a hole it is absorbed.
Absorption is indicated by a red marker at the ray's entry point.
- Reflection. This simply means the ray returns to the same location it
left from. This could be do to multiple deflections, trying to pass between
two holes that are opposite of each other, or a hole that exits adjacent to
the rays entry point. Reflection is indicated by a yellow marker at the
ray's entry point.
Examples
This example has all possible ray entry points marked. Absorptions and
reflections are shown as the appropriate color (red and yellow). The purple
triangle illustrates a deflection. All other rays simply pass thorough.
The black hole is indicated by the ball shape.
This example illustrates another way to get a reflection.
A ray must be able to travel between the holes to be relected back.
Careful, it is easy to get fooled. Here it appears that a ray passes
straight through, when in reality it is affected by several holes.
