Black Hole Game For Windows
Program Description: Black Hole is a small solitaire puzzle game, where you launch probes into an un-explored quadrant of space in search of clues to the hidden locations of a number of invisible black holes. Your probe's trajectory will respond to the invisible gravitational wells surrounding the Black Holes, sometimes with unexpected results.

By carefully analyzing each probes entry point and exit point (if any), you usually can gain enough clues to mark the sectors of space where you think the Black Holes are located. The object of the game is to correctly mark all of the hidden locations using the fewest number of probes, earning the highest score.

Rules and Game Play:
Click on SETTINGS to select the desired number of hidden Black Holes.

Click on GAME NEW to reset for a new probe run.

Launch probes by clicking on one of the buttons surrounding the quadrant grid. The probe will enter the quadrant at the sector closest to the launch button selected. Once launched, the probe will do one of three things.

1. The probe may fall directly or indirectly into a black hole, in which case a red marker will be placed at the probe's entry point.

2. The probe may exit the quadrant at the same point it entered, in which case a yellow marker will be placed at the probe's entry/exit point.

3. The probe may exit the quadrant at a different point from where it was launched, in which case matching blue markers will be placed at the entry and exit points.

Gravitational effects:
1. Left to itself, a probe's natural tendency is to travel in a straight line. If there are no Black Holes directly in front of, or on either side of the probe's course, the probe will exit the quadrant at the location directly opposite it's entry point.

2. A probe may NOT travel past a Black hole that lies directly in FRONT of it's path. The strong gravity draws the probe straight towards the Black Hole. Once it passes the event horizon, it disappears down the gravity well in a blinding flash of light. Fortunately, you are too far away to see it, because if you weren't, your singleship is already too close to escape the strong gravity gradient.

3. A probe may NOT travel past a Black Hole that lies on either side of it's direct path. Instead, the probe's path is diverted 90 degrees away from the NEAREST CORNER of the sector containing the black hole. It turns BEFORE it reaches the Black Hole. Sometimes, the Black Holes cause the probe's course to change many times before falling into another Black Hole or exiting the quadrant.

4. If a probe simultaneously encounters Black Holes directly in front of it's path, and on either side or both sides of it's path, the Black Hole directly in FRONT of the probe will have the strongest attraction causing the probe to continue straight and fall in.

5. If a probe simultaneously encounters Black Holes on BOTH sides of it's path, but NOT directly in front of it's path, the probe's path is diverted 180 degrees and the probe returns to it's entry point.

6. Because of rule 3, a probe may NOT enter the quadrant at all if there is a Black Hole next to the EDGE of the quadrant on either side of it's entry point. The probe will exit where it went in.

7. Because of rule 4, a Black Hole at the EDGE of the quadrant directly in FRONT of the probe's path will still have the strongest attraction, overriding rule 6.

8. Use the Help / Examples to understand these gravitational effects more clearly. You can also do random sample runs and get all of the black hole locations and probe results to study until you get the idea.

Marking Sectors:
Click on any sector grid to toggle a sector marker ON or OFF. You can place as many or as few markers as you want while you are analyzing your probe results, but you must have the exact same number of markers as there are Black Holes before you may make your final guess.
Ending the game:
When you think that you have launched enough probes to determine all of the hidden locations, and when you have marked all of the sectors that you think contain Black Holes, select the DONE button in the lower right corner to make your final guess and end the game.
Games with 3 Black Holes are always simple and straight forward.

Games with 4 Black Holes are usually a little harder to solve.

Games with 5 Black holes are the hardest. Very interesting patterns turn up.

It is not always possible to test the contents of every sector. Sometimes patterns can occur that may block or divert your probes.

Often, if you guess too soon, you find that there are other arrangements of Black Holes that also satisfy the probe results. You might need to launch an extra probe or two just to be sure which conditions are correct.

The trick to scoring high is to study the results carefully and select the best possible probe to launch next. Also, try to select the probe which has the best chance of yielding the most information.

On the other hand, you don't want to waste your probes either. Try not to launch any probes that might tell you information you already know, unless you really have to.

And finally, as a method of last resort when you have ruled out all other possibilities and nothing else seems to work, you just might have to make an informed guess.

Support: Built-In Help / Example System. This web page and the Read-me file included is all of the additional support I can provide for this program. Black Hole has been tested and de-bugged on Win 95-98 and XP. There is also some support for other Windows  versions, but it has never been tested on other platforms.  In theory, it should run on Windows NT, Windows Me, Windows 2000, and Windows XP. If you try it with other versions, let me know the results. Please print this documentation page for future reference. There are no plans for future versions or improvements.
