PROLOGUE: CENTURY PARK
----------------------

The prologue to "Jigsaw", like the prologue to "Adventure", is a matter
of collecting equipment and finding your way into the rest of the game.
But it's not just an object-finding exercise, it's a matter of
collecting the major themes of the game: is it the end of the twentieth
century, and the game will explore the whole of twentieth-century
history; there are fifteen minutes to go before midnight, and each
remaining minute corresponds to one of the fifteen remaining episodes in
the game; and you get to see the traces left by Grad Kaldecki and the
stranger in black (who you will be trailing after for the rest of the
game).  But enough fore-shadowing, on with the game.  First is a light
source...

    southeast
    get rucksack
    examine crate
    get key,device
    examine rucksack
    examine key
    examine device

The description of the rucksack is an allusion to "Curses", hinting that
the protagonist of "Jigsaw" is the same as the Meldrew heir in Graham's
earlier game (though nothing else is made of this hint).  The
significance of marking "A.4" will become apparent later.  It is not a
coincidence that the reading "99" on the curious device is the same as
the last two digits of the current year.  The inscription "tempora
mutantur, nos et mutamur in illis" means "times change, and we change
with the times".

    northeast
    east
    examine statue

Grad Kaldecki's motto "felix qui potuit rerum cognoscere causas" means
"happy is he who is able to know the cause of things.  Ironic, because
one of the morals of "Jigsaw" is that causes are very uncertain things
indeed.

    east
    open stool
    get sketch book
    look under stool

    west

The significance of the sketchbook won't become apparent until the very
end of the game.  But for now, all you need to know is that sketching
animals is a useful thing to do.

Leave the case for later.  You appear to be trapped inside the pyramid,
so let's hope you've done everything from the prologue.

    east
    look under table
    get jigsaw piece
    examine it
    examine table
    clean table
    examine board

Now some of the mysteries are reasonably clear: the game is going to
involve a jigsaw-piece-collecting exercise, with the end of the game on
completion of the jigsaw.  The marking "A.4" on the crate suggests that
the corner piece goes at location a4 (you may have to "turn corner
piece" a few times to get it the right way round), and the pencilled
"Southwest?" on the centre piece suggests it goes southwest of the centre,
namely at c2 (again, you may have to try it in several orientations
before it fits).  Luckily, the board itself tells you when a piece fits.

Note that the status line has changed; the mysterious numbers are your
score, the number of jigsaw pieces successfully entered into the board,
and the number of turns so far.

    [put corner piece at a4]
    [put centre piece at c2]
    get clock
    turn hand to 59

The pyramid and jigsaw turn out to be a baroque time machine, and the
clock is the device for controlling it.  You are advised to experiment
for yourself, but in summary: turning the clock's hand lights up the
board; if the alarm is on and the clock reaches 0, then you are
transported back to the pyramid from whatever time zone you are in.  So,
off you go:

    press a4
    press c2


CHAPTER 1: RICOCHET
-------------------

    examine device
    examine street
    examine cafe

It's June 1914, and you're in Sarajevo.  What could be more ominous?
And then Black enters.  Black is a strange character, partly villain,
and partly love-interest.  You'll find as you progress, that you are
doomed to trail around history in Black's wake, fixing the problems left
behind.  But you had better be polite to start with.

    shake hands
    examine black
    z.z
    say no to black
    unlock dresser with key
    open dresser
    get jigsaw piece from dresser

    ask black about archduke
    examine rifle
    turn safety off
    ask black about pyramid
    examine student
    z.z.z.z.z

Black's plan is to assassinate the student, thus preventing World War I.
Might that not be a good thing?  Millions of men died in savage and
futile battles in the fields of northern France.  But it turns out that
you have no choice here: you must preserve the course of your own
history, regardless of how bloody, brutal and senseless it is.  This
attitude to history is a strange one: on the one hand history is so
fragile and contingent that the slightest push can topple it into chaos,
and on the other, there is only one true version of history that must be
preserved at all costs.

    shoot archduke
    z.z.z.z.z

The deed is done, history is safe, and you have a plot and some clues.
Black intends to improve history; you know however that this cannot
work.  When a crisis in history has been resolved, a "cloud of disturbed
air" appears, and with the aid of the curious device it is possible to
condense this cloud into a time window (the black sphere) and enter a
mysterious realm called "the Land".  But without the device, you cannot
go there yet, and must resort to the clock.

    turn clock to 1
    wait

CHAPTER 2: ICY CALM
-------------------

    get times, note
    read times
    read note
    southwest
    north

You turned the clock off because you'll be spending more than an hour in
this time zone.  The note is addressed to "White", which must be you
(the good one, as opposed to the villain Black).  Where are you?  It is
1912, you are on an ocean liner, the notepaper is "White Star Line", and
you have just collided with an iceberg.  Could it be that you are on
board the H.M.S. Titanic?

The Titanic appears to be sinking as expected, despite the calm of the
passengers and crew.  How could the course of history be affected?  If
you wait near Benjamin Guggenheim (disguised as an officer), you will
eventually receive a secret letter to deliver.  But of course, you'll be
leaving the ship by time-travel, not by lifeboats, so you'd better find
someone to act as courier for you.

    examine secret letter

    say hello to miss shutes

    get jigsaw piece

The jigsaw piece must be very big to have passed as a ouija board!  The
clue here is that anything square and coloured white or grey is probably
a jigsaw piece, so you had better be on the lookout.  Now you need to
find your way into Black's cabin:

    open door
    east
    get long barrelled key
    look under wardrobe
    read second note
    examine kaldecki detector
    spin it

The Kaldecki detector is a device that detects jigsaw pieces; it rings
the bell when you haven't found all the jigsaw pieces in the time zone.
Luckily, the missing piece is close at hand:

    open window
    get jigsaw piece
    spin kaldecki detector

So there are no more to find here.  What about that towel you saw the
stewardess take away, the one with all the mathematics on it?

    west
    stewardess, give me the towel
    examine towel

The towel tells you when and where the time window will open.  Remember
this information.  Now you must make sure that the secret letter gets to
safety by ensuring that the S.S. Carpathia is around to pick up the
lifeboats.  Recall from reading the "Boy's Book of the Sea" that the
distress prosign is CQD (actually, by the voyage of the Titanic, the
International Maritime Convention had agreed on the new prosign SOS -
but the radio operator on the Titanic sent both).

    west

    unlock door with long key
    open door
    wear jacket
    east
    examine charts
    dah.dit.dah.dit
    dah.dah.dit.dah
    dah.dit.dit

You have now saved history from disaster.  If you want to visit the Land
now, then go to the place written on the towel, wait for the right time
(just before the ship sinks) and activate the curious device.  However,
there'll be plenty of time to visit the Land later in the game, so you
can escape using the clock instead:

    turn clock on
    turn clock to 1
    wait
    northwest
    [put the edge piece at b1]
    [put the corner piece at a1]
    turn clock off
    turn clock to 59
    press a1


CHAPTER 3: AND ONE PERCENT LUCK
-------------------------------

Actually, there's no particular reason to choose A1 rather than B1;
Jigsaw has few dependencies between its time zones, so you have a lot of
freedom about which order to visit them in.  This solution chooses one
ordering; there's no reason why you shouldn't choose a different one.
It's a good idea to spin the Kaldecki detector at the start of a time
zone to see if you need to search for jigsaw pieces, and to spin it
after you pick up each jigsaw piece to see if there are any more.

    examine device
    spin kaldecki detector
    open upper door
    open lower door

It's 1928, and Alexander Fleming is about to discover penicillin.  With
your help, that is.

    south
    east
    up
    get certificate
    get jigsaw piece
    spin kaldecki detector
    search dishes
    get mouldy dish

Fleming should have come in by now and deposited his suitcase (if not,
wait a bit).  He doesn't appear to be a very observant man, as he's
missed both you, and the mouldy petri dish.  How to bring it to his
attention?  He would notice something as large as a suitcase in the
wrong place:

    examine suitcase
    push suitcase east
    put dish on suitcase
    [wait until Fleming finds the mouldy dish]
    [wait until the disturbed air appears]
    press white button
    enter black ball
    z.z

And now you're in the Land.  The Land is a four-by-four grid of
locations, each one corresponding to a square on the jigsaw board.  The
locations covered in thick mist correspond to the jigsaw pieces that you
haven't placed in the board yet.  There's nothing much to do here at the
moment, though it's mostly harmless to explore (but if you go southeast,
then east three times, you'll regret it).

It's 1922; Proust is soon to die in Paris, and the manuscript of "A la
Recherche de Temps Perdu", one of the greatest novels of the twentieth
century, is almost finished.  (If Proust was searching for his lost
time, what are you and Black searching for?)

Now you are lost in a maze, but fear not! it isn't difficult.  Wait for
a while, and you'll see various authentic Parisian characters go past.
Which way are they all going?

A crucial passage of "A la Recherche" has escaped; clearly you must find
it or else history will be wrecked for lack of it.  (Perhaps not every
reader of Jigsaw will have quite such a high regard for Proust's novel
as Mr Nelson clearly has.)

It is April 1917.  The Russian Revolution is in full swing, Lenin is on
his way to Moscow, and Black plans to delay or stop him.  Once again,
the right thing to do is debatable.  Stalin killed or exiled millions of
his countrymen; might it not have been better if the Revolution had been
stopped, or diverted?  But you have little choice in the matter.

No doubt the tied-up British officer is the work of Black.  You
shouldn't wear the British army uniform quite yet, because the soldiers
won't talk to you when you're wearing it.  Now a couple of get-x-give-x
puzzles follow:

You have a jigsaw piece.  But it's not so easy to keep it, because if
you leave the smoking compartment carrying it, the angry passengers
relieve you of it (even if you hide it in your backpack).  You could of
course escape using the clock, but it's cleverer to find another way of
disposing of it - which incidentally reveals Black's dastardly plan -
and the "lack of ventilation" is a clue.

history was supposed to have been changed.  But still, it's easy to save
Lenin:

It is August 1967 and the Beatles are having trouble with their latest
album.  Black intends to ruin the fabric of the British musical industry
by planting 1970s progressive rock tunes into the fertile soil of
psychedelic rock-and-roll.  Since violence is not an option, there is
clearly only one way of stopping up Black's mouth:

It's 1975 and we're somewhere in North America: probably Canada or
Alaska.  It's in such wildernesses as this that the USA keeps its
nuclear deterrent, pointed across the north pole at the cities and
military bases of the Soviet Union.  Black's clearly been up to no good,
but whatever cunning plans were hatched have gone wrong.  Perhaps you
can right them?

    examine snow goose
    sketch snow goose

The snow goose isn't the only wild animal around here.  If you wander
around in the forest, then eventually a snow leopard will stalk up to
you, and wait around while you draw its portrait (but they don't have
snow leopards in Canada...).

The moral of this episode seems to be that fooling around in time can

no choice but the create the crisis and then avert it:

In 1903 the Wright brothers made the first powered heavier-than-air
flight.  It seems as though Black has decided not to interfere here, but
you still need to help the brothers along a bit, because the aileron
from the "Flyer" is another jigsaw piece, and they're hardly likely to
let you just walk off with a piece of their plane, unless the flight
were a success and they'd all run off to town to telegraph the news.

The wind speed in Dune Valley varies in a cycle of five turns, and the
brothers try out the flyer once every five turns.  Unfortunately, the
two cycles are synchronised so that the brothers launch just one turn
too late to get the strongest headwind.  If only you could delay them
for three turns, they'd have a chance.  Luckily Orville is fond of music,
so wait until Orville has landed here (now, for example, if you're

The second jigsaw piece is the lid of the heater, but it's not easy to

there's a way to stop up the air holes.

CHAPTER 9: THE HIGH POINT
-------------------------

    examine device
    spin kaldecki detector

Now the rules have been changed.  Black is not interfering with an event
from the history you know, but from some other history.  How can this
be?  Perhaps Black is from some alternate present.  Might it be
conceivable that Black's present is a disaster, and that Black's clumsy
muddlings in history are an attempt to produce something better?  This
would give Black a more honourable motive than seems plausible from what
has happened so far, but on the other hand it's very hard indeed to
believe that our own present is the best of all possible worlds.

The word "Waldo" to refer to a teleoperated device comes from the Robert
Heinlein novel of that name, about a severely physically handicapped
genius who attempted to rule the world by remote control.  Waldo was
also the name of one of the teleoperated robots in the Infocom game
"Suspended".

You can't take the fuel rod without dying from radiation poisoning (and
no doubt giving the Apollo 17 astronauts a shock when they find your
body).  But you can make it a bit less likely to break by bandaging it:

    wrap rod with foil
    drop all
    get rod
    put rod in reactor
    drop rod
    get all except rod

No doubt you will suffer nasty cancer of the hands in later life from
handling the plutonium rod, but for now you don't seem to be suffering
radiation poisoning.  However, you can't hold the rod and open the door
at the same time, so you need some help.  Luckily Waldo can come to the
rescue.  The puzzles involving Waldo are great fun, and you would do
well to experiment with the robot before coming back to the solution.
You need to be in the "Othello" to program it; simply "type x y", where
"x" is a command (rturn, lturn, forward, sample) and "y" is the number
of times the actions should be repeated.

However, it's a bad idea to solve the reactor puzzle straight away,
because when you do that, the time crisis will be resolved, and Black
will steal your spacesuit, leaving you unable to find the jigsaw piece.
So you should find the jigsaw piece first, and then come back to the
reactor.

to distract them; since they're looking for interesting geological
samples, perhaps they would appreciate the green clod?

    throw green clod at astronauts

Since sound does not travel in vacuum, the astronauts don't hear the
thud of the rock landing.  But you still can't approach the rover.
However, Waldo is smaller than the crater rim, so if you can program
Waldo to walk round the crater, get the piece (using its sampling arm)
and return, you could get away without alerting the astronauts to your
presence.

you simply turn it round and set it going again.

CHAPTER 10: THE GHOST OF THE B-29
---------------------------------

You're on board a B-29 bomber, flying over the north Pacific ocean.
Somehow, the left engine has become damaged (perhaps the bomber was
fired upon, or perhaps it was just an accidental engine failure).  The
crew have parachuted out, and taken all the parachutes with them.  Your
only hope is to land the plane, but you don't have enough fuel to make
it back to the USA, and will have to attempt a landing on Soviet soil.

This puzzle is difficult.  If you've failed to solve it so far, and need
some help, read the following.

The last two indicators on the status line of the cockpit are the
plane's bearing in degrees (clockwise from north) and its position
(x,y).  The buttons which you can use are AUT/P (autopilot), CUTENG/L
(turn off the left engine), CUTENG/R (turn off the right engine),
LOWER/U (lower the undercarriage) and REL/B (open the bomb bay doors).
If you need more fuel, then you should cut the left engine, go to the
west side bomb bays, and press the RES/F (reserve fuel) button.  You can
do this as often as you need to.

The radio in the navigators chair is picking up a signal from a Russian
base.  The radio has a three-figure display, showing the bearing of the
plane from the base; you should head in the direction 180 degrees from
this bearing.  Finally, if you clean the pinup of Diana Durbin, you'll
find a secret message.  If that doesn't help, try heading for the
position (1945,1970); an error of +-100 is acceptable.

Finally, if even the above doesn't help, here's an example walkthrough:

    north
    push throttle
    turn aut/p on
    z.z.z.z
    z.z.z.z

    again
    again
    z.z.z.z
    z.z.z.z
    z.z.z
    press lower/u
    land

You've landed the B-29, but the crisis isn't over; you've merely arrived
in the right place.  Black has been double-dealing with the Soviets and
the Americans, for the usual convoluted reasons.  You must make sure
that Black and all other traces of the future are removed before the
Soviets get their hands on them.  You will notice (if you type `out')
that you won't be able to get back into the plane if you get out.  So
first, you need to get the heavy safe out of the plane so you can deal
with it on the ground.

don't believe him.

CHAPTER 11: BANBURISMUS
-----------------------

The rules have been changed yet again.  Now you are in the past in a
ghostly form, unable to do anything except move around, examine things,
and (taking advantage of your incorporeality) jump, and fly.  The
information to be gained here is quite important, so remember everything
you see here, especially the first two numbers on the paper (call these
numbers X and Y).

It's 1941, and Black's plan this time is to be a British agent, spying
on Germany for the British and sending messages in the Enigma cipher.
Knowing Black, the messages will give misinformation of some sort.  If
you (a suspected German spy) can decode Black's message, the people at
Bletchley Park will think that Black is actually a double agent, and
proceed to disbelieve Black's misinformation.  So all you have to do is
to decode Black's message.

Before you go to the walkthrough below, think for a moment of Turing and
Newman and the other Bletchley Park cryptographers.  When they were
stuck, they couldn't go to a walkthrough.  They didn't have information
magically obtained by a ghost.  And if they failed, worse things were at
stake than merely failing to win an adventure game!

If you're really stuck, then try the following:

    read intercept
    examine crate
    open crate
    again
    get enigma
    examine enigma
    get wheel ii
    get wheel iv
    get wheel v
    put wheel ii in enigma
    put wheel iv in enigma
    put wheel v in enigma
    unstecker
    stecker a to g
    stecker w to c
    stecker v to t
    stecker u to j
    stecker y to r
    turn machine off

Why all the above?  You know that Black must have been using code wheels
II, IV and V because wheels I and III were on top of the wardrobe.  You
know five of the steckerboard connections because they were written on
the torn scrap of paper.  You also know that there are two more
connections to make (the remaining three wires could be seen dangling
from Black's machine).  The machine has two modes (on and off), each of
which decodes messages encoded by the other.  State on is typically used
for encoding and off for decoding.

How to decrypt?  You know the settings for wheels II and IV (they were
on the torn scrap of paper) and there are only ten settings for wheel V.
Try all ten possibilities.  Because there are only two stecker
connections missing, you expect that about 8/26 letters will be wrong
(this is because each letter has two opportunities to be transformed by
the steckerboard, and there are four letters involved in the unknown
connections).  Look for output that might consist of English words if
about a third of the letters were changed.  Try to guess some of the
wrong letters, and see if you can make stecker connections that correct
these letters.

If you couldn't work this out on your own, then here's a walkthrough:

    stecker d to f
    stecker x to p

Then try the following with Z one of 6, 18, 5, 4, 21, 23, 14, 2, 8 or
17, until you get it right.

    set ii to X
    set iv to Y
    set v to Z
    type intercept

Well done if you solved it on your own, shame if you had to resort to
the walkthrough!

nothing world-shatteringly important has happened since then.
