Ball Puzzle
-----------

Now this puzzle can of course be solved a number of different ways like a lot
of puzzles, but I find this way to be the easiest.


When using the scale, the following happens each time you click the middle of
the scale.

Click #1 - First weighing
Click #2 - Reset the scale
Click #3 - Second weighing
Click #4 - Reset the scale
Click #5 - Third Weighing
Click #6 - Cutscene that shows new set of balls being swapped in [puzzle
resets!]

So Once you've done your third weighing and you've found the right ball DON'T
click the scale or you'll reset the puzzle!


For all cases you start by putting balls 1-4 on the left and balls 5-8 on the
right, then weighing them.

=================================CASE 01: EVEN=================================

This means that balls 1-8 are normal balls and the one that's different is in
balls 9-12.

So leave ball 12 behind and put 9 & 10 on the left scale and 11 on the right
scale with ball 1 (one that we know is normal).

WEIGH THEM


A) If they're even once again, then the ball you want is the one that you left
out (12) and you're done!

B) If they're different then you need to make a note of which side is heavy and
which side is light. (eg: 9H, 10H, 11L | 12 you don't care about because you
know it's normal.)


Weigh the two similar balls against each other (one in each side) and leave the
third one out. [So in the example above the two similar balls are 9 and 10
because they were both on the heavy side, while 11 was the only ball on the
light side. Remember that 12 was a normal ball, it just happened to be on the
light side.]

1. If the two similar balls are equal, then the one that you left out (11) is
the one that you want.

2. If the two similar balls are different then have a look at what you
classified them as in the last step. If they were both H's (heavy) then the
heavy ball is the one you want, if they were both L's (light), then it's the
light ball that you want.

=================================CASE 01: EVEN=================================


=======================CASE 02: LEFT LIGHTER THAN RIGHT========================

This means that the unique ball is among balls 1-8, mark balls 1-4 as light
(eg: 1L, 2L, 3L, 4L) and balls 5-8 as heavy (eg: 5H, 6H, 7H, 8H).

Put 1L, 5H & 6H on the left side and 2L, 7H, 8H on the right side [as you leave
out 3L and 4L].

WEIGH THEM


1. If they balance then the unique ball is one of the two that you left out
[3L,4L]. Weigh either one of those against any other [normal] ball.

1A) If they're equal then the ball that you left out is the unique one.

1B) If they're different then the ball that you weighed against the normal ball
is the unique one.


2. If the left side remains light, then the unique ball is one of the
following: 1L, 7H, 8H. Now put 7H on one side and 8H on the other side and
weigh them.

2A) If they're equal then the ball that you left out is the unique one.

2B) If they're different, then the ball that's on the heavy side is the unique
one.


3. If the left side changes to heavy, then the unique ball is one of the
following: 5H, 6H, 2L. Now put 5H on one side and 6H on the other side and
weigh them.

3A) If they're equal then the ball that you left out is the unique one.

3B) If they're different, then the ball that's on the heavy side is the unique
one.

=======================CASE 02: LEFT LIGHTER THAN RIGHT========================


=======================CASE 03: RIGHT LIGHTER THAN LEFT========================

This means that the unique ball is among balls 1-8, mark balls 1-4 as light
(eg: 1H, 2H, 3H, 4H) and balls 5-8 as heavy (eg: 5L, 6L, 7L, 8L).

Put 5L, 1H & 2H on the left side and 6L, 3H, 4H on the right side [as you leave
out 7L and 8L].

WEIGH THEM


1. If they balance then the unique ball is one of the two that you left out
[7L,8L]. Weigh either one of those against any other [normal] ball.

1A) If they're equal then the ball that you left out is the unique one.

1B) If they're different then the ball that you weighed against the normal ball
is the unique one.


2. If the right side remains light, then the unique ball is one of the
following: 5L, 3H, 4H. Now put 3H on one side and 4H on the other side and
weigh them.

2A) If they're equal then the ball that you left out is the unique one.

2B) If they're different, then the ball that's on the heavy side is the unique
one.


3. If the left side changes to light, then the unique ball is one of the
following: 1H, 2H, 6L. Now put 1H on one side and 2H on the other side and
weigh them.

3A) If they're equal then the ball that you left out is the unique one.

3B) If they're different, then the ball that's on the heavy side is the unique
one.

=======================CASE 03: RIGHT LIGHTER THAN LEFT========================

Snooping
--------

Once you've done three weighings and you think you've found the right ball,
click that ball and it should go into your inventory. Now MAKE SURE you don't
click the scale or you'll reset the puzzle. Instead click the arrow in the top
left to exit the puzzle. Now pass your cursor over the ball in your inventory.

If it just says "white ball" you messed up somewhere, but if it also says
"unique specimen very hard to find" you've got the right ball.

Once you have the right ball SAVE YOUR GAME so you never have to do this puzzle
again!
