Welcome!

This tutorial will teach you how to play KBlackBox, using a simple example.<br /><br />We are playing with a square black box of 6 columns and 6 rows. It has 3 balls <b>hidden</b> inside it and 24 laser probes around it.<br /><br />The goal is to <b>find the positions of the balls.</b>

Black box principles

The balls are not visible, but we can shoot laser beams into the box at different entry points and observe if the laser beams leave the box, and if they do, where they come out.<br /><br />The laser beams interact with the balls in various ways.

Please click on the marked laser to shoot a beam into the black box.

No interaction

If a laser beam does not interact with any ball in the black box, it comes out at the point opposite the entry point.<br /><br />Example: Suppose we have 3 balls in the box as shown. They will not affect laser beam "1".<br /><br />As the game progresses, each pair of entry/exit points is marked with a different number.

Now shoot the marked laser to discover the first kind of interaction.

Hit

A direct impact on a ball is called a "<b>hit</b>". A beam that hits a ball does <b>not</b> emerge from the black box.<br /><br />Example: The beam might have hit a ball at the position shown, but the exact position of the hit is not certain: There are many other possibilities.

Shoot the marked laser to discover the second kind of interaction.

Simple deflection

The interaction of a beam that does not actually hit a ball, but aims to one side of it, is called a "<b>deflection</b>". The angle of deflection of the beam is always <b>90 degrees</b>.<br /><br />Example: The ball shown would deflect beam "2" upward, as shown, but this is <b>not</b> the only possibility.

Click on "Next" to see another combination of ball positions that deflects the laser beam as shown.

Several deflections

As you can see, interactions in the black box can be quite complicated!<br />A laser beam entering and exiting at the positions "2" might have been deflected by this configuration of 3 balls.

Shoot the marked laser to discover another kind of result.

Reflection

If the laser beam leaves the black box <b>at the entry point</b>, it has been reflected backward inside the black box.<br /><br />Example: We have placed 2 balls for you in a configuration that would lead to such a reflection.

Shoot the marked laser to see another backward reflection case.

Special reflection

If a ball is <b>at the edge of the box</b> (with no other ball nearby), a beam which is aimed into the black box directly beside it causes a backward reflection.<br /><br />Example: The configuration shown can cause a backward reflection.

Nearly done. Click on "Next".

Marker for "free position"

We are sure there are no balls in the first 2 columns. If there were any, the beam entering at position "1" would hit a ball or be deflected by a ball in column 2. You can mark a "free position" with a right mouse click (see also keyboard shortcuts).<br /><br />Example: There are 12 markers in the first 2 columns.
