Big Dome Island
After the animation, leave the
cage and look over the side of the cliff on your right. The
guy that got hit with the dart is laying down there. But that's
not important right now. Go up the stairs to the start of the
bridge. Turn left and you will see a gold room. You may want
to look in the beetles before proceeding. The room has two doors
and 5 passageways leading from it. The button to the right of
the entrance rotates the room.
Hit the button 4 times (you will
see a cool animation 4 times) and you should be facing a dark
wall with a peephole. Turn around and continue to follow the
stairs down the other side of the hill. Turn left when you reach
the end of the path and you should see a locked gate.
Go under the gate and through the
cave. You should see the gold room again with a passage leading
to another cave through the room and slightly left. If you do
not see this, go back to the button to rotate the room again.
Continue to hit the button and then check the rotation in the
cave until you do.

In the second cave there is a lever
on a pipe. Turn it, these kinds of levers power various items
on the islands of Riven. Most on the time by diverting water
or steam to the appropriate location. Turn around and go to
the doorway of the room with the lever leading back into the
gold room. You should see a switch on your left; these types
of switches open gates and doors. Flip it, do not hit the rotation
button, just the switch. Return to the first rotation button
and hit it 4 more times. You should now be facing a passage
to the "Back Door" (see diagram, this is a door, not a gate)
across the gold room and slightly right. Go to this door (you
cannot open it right now), turn around, and you should now flip
the switch you see (looks a lot like the cave switch) Again,
do not hit the rotation button. Go back to the first rotation
button and hit it two more times. Now you should see the gold
room with and passage leading across a bridge across the room
and slightly right. Now, go across the bridge to the large domed
building. If you are stuck after reading all this refer to the
diagram and you should get an idea of the basic structure of
the room and you should be able to get to where you want to
go. Follow the catwalk through the domed building until you
are outside again. Follow the catwalk outside until you come
to a lever and a pipe much like the one in the cave, flip this
lever. Follow the catwalk some more and you will find another
lever similar to the first two. Flip this lever in the similar
manner. Return back the way you came to the button which rotates
the room. Hit the button 3 more times, this will help you later.
Now you can go away from the gold room across the bridge to
the other section of island. Go through the door on the left
midway through the tunnel.
Sit it the chair if you like, it
doesn't do anything right now. Look around and find the red
and gold view portal. Hit the level next to the portal and continue
down the tunnel. Go through the room of pillars. (This room
and the room with the chair are important to the plot of the
game, do you see any connections?) Leave by way of the large
door the switch near the view portal opened. Hit the blue button
to summon your transportation to the next island. Get in the
transport. Hit the lever on the left to turn around and the
switch in the middle to go! This is on of the best parts of
the game, so enjoy.
Forest Island
Get out of your transport
and go through the hole in the rocks. Go UP the stairs to the
chopped forest. Keep to the path of the right and you should
find a hold with a cart. Get in the cart, hit the lever and
go! This is also one of my favourite parts.
Paper Island
Not much time on the last island,
this one is better. Climb down the ladder and make your way
out to the switch in the middle of the lake. Turn the lever
so it is in line with the middle pipe (toward bottom right of
screen). Then head for the cylindrical building. Go up the stairs
on the side of the building. The stair lead to a mess of switches
and a window in to the building. Turn the big wheel first. Then
look left and switch the lever where the single pipe switches
into two. The white dot should be on the bottom pipe. Turn to
the window again and hit the switch on the right to the up position,
then turn the lever on the right to the up position also. Now
you can enter the building. Go into the building and down the
ladder. The screen will get darker as you proceed. Just keep
clicking in the centre until you see daylight. You will be treated
to a nice view as you exit the pipe. Follow the mountain pass
over the fence to the double doors. Go through the double doors,
but shut them behind you. There is a path on the right that
will be revealed. Follow this path outside again and look for
a grey lever on the right of the bridge. Hit this lever and
return to the double doors. This time take the path you would
have taken had you gone straight through the double doors. You
should go up some stairs into the cavern. When you get to the
silver ball with holes in it, look up and climb through the
fan vent. This leads you into Ghen's laboratory. Cool huh? Read
the book on the table and find the five numbers in a row (refer
to Rivenese number graphic)

Write down this combination. Leave
the lab through the door with the blue button next to it. Hang
a right out of the door and keep walking on the VERY long bridge
back to big Dome Island. Hit the lever to lower the last section.
Insert disk 2.
Big Dome Island
Again, follow the catwalk
around the inside of the big dome until in ends. Turn the wheel
to raise the missing section. After crossing the raised section,
immediately turn left and head out of the dome. A section of
the bridge will be missing. Turn around and hit the button to
the right of the door. Turn back around and continue on the
bridge. Hit the switch to open the door and go up the ramp to
the grip. Place the marble in the grid as shown in the picture.

Turn around and click the switch
on the left wall. Pull the switch down and push the white button
it was covering. You will hear a noise, leave the switch down.
Go back down the stairs and back through the Gold Room to the
Bridge and the first rotation button. Hit the button 3 times
and go through the gold room again back into the Big Dome. Follow
the catwalk outside the dome but stop right before the path
goes through the rock. Turn right and hit the button. You will
be lowered. Turn around and go up the stair and along the path
to the spinning dome. Look through the viewer and click the
button on top when the gold eye is showing. This may take a
couple tries. The Dome will stop and open. Go up to the dome
and enter the code you learned from the book in the laboratory.
Open the book and touch the cool animated picture.
Ghen's House
You're in a cage again. Turn around
to find the button and push it. You will be rewarded with a
seven-minute speech by Ghen on how he has changes his ways (he
hasn't he's evil.) After his speech find the book with the most
blocks on it. Open it and touch the picture.
Tree Island
Back away from the linking book
and hit the button on the floor. Turn around from the sphere
and go left up the stairs. Enter the little building and sit
down. Hit the lever on the left (nice view!), hit the lever
on the right, and then the one on the left again. Go out back
down the path past the down and into the tree. Pull the lever
on the right and an elevator will take you down. Get out of
the elevator and push the switch on the left. You can now walk
out of the fish's mouth (another clue to the intentions of Ghen).
Follow the path and you will see a little kid. Follow her by
taking the path on the right and up the stairs. Go through the
gate and hang another right. Keep following the path, the villagers
will always run from you. Go up the ladders to the houses and
keep going until you see and alter and a submarine type machine.
Hit the lever next to the submarine and go back to the gate
you came through. Don't go back through the gate, continue on
the path and down the stairs (you should recognise this area).
You will see an animation of the penguin/dinosaur looking sea
creatures. As a side note, the longer you wait between moving,
the closer you can get to them. Stay on the path and you should
come to some ladders. Go down the ladders to the submarine.
The lever that moves in an arc turns the submarine around, the
lever that slides side to side determines if the submarine will
take the left track or the right track. The lever on the right
makes you move forward to the next junction.

If you don't want to follow my
directions here, all you need to do is go to the switches, flip
them all up, then to go the cone and get out - you can skip
down to the orange submarine (yellow doesn't show up well).
If you do want explicit directions, read on. Turn around and
go forward. Make sure the sliding lever is on the right and
go forward again. Open the hatch and climb the ladders up to
the switch building. Move all the levers to the up position
and go back to the submarine. Turn around, go forward, turn
around, slide the lever to the left, go forward. Get out of
the submarine, go into the pyramid and pull the triangle thing
in front of you. Click on the seat that lowers. You will see
a prison, open the door by turning the crank on the right. Go
into the cell and open the drain of the floor. Touch the water
and a passage will open. Keep going down the dark tunnel until
you reach the water. Screw in the light on the left, turn around
and go back down the tunnel slowly, turning on a light in each
frame, they are sometimes difficult to see. Once you reach the
end, turn around and go back down the tunnel. You will notice
a door, open it and go through. Push down the stones you see
in this order:

Rebel Island
Touch the book that comes out.
You will get a nice view on the rebel base, the only nighttime
shot in Riven. Turn around and head for the book. You'll get
darted. Wander around your cell for a bit and enjoy the view
out the window and the door. Eventually a lady will come in
and give you Catherine's journal and the prison book you lost
in the beginning. Look through the journal for a series of five
numbers. You will need these later. The lady will return with
a linking book for you to go through.
Tree Island
You will return to the room with
the stones. Go back down the tunnel and pull the wire to open
the passage back to the cell. Exit the cell and go right. Lower
the ladder and go down it. Turn around and go back the way you
came after lowering the submarine. Except, stop were all the
tree are cut down and take the mine car ride again. (This is
cool anyway). Remember where those double doors were? Go there.
Except, close the doors behind you and go left this time. Go
down the stair to the door. Open this door, go through, and
close it behind you. Go down the tunnel that was behind the
door and open the spinning dome by clicking on the gold eye.
Enter the same password to get to the book and link back to
Ghen's house.
Ghen's House
You'll talk to Ghen again. Go through
the back when he asks you to, he will take your place when he
goes through. After capturing Ghen, find the hole in the floor
and go down. They're in a silver thing on his dresser. It makes
five sounds in a row, either a ding, a clank, or a creak. Write
these down. Go back up the ladder and pull the handle just clockwise
of the hole. Then go and click on the book with the least blocks.
Catherine's Island
Once away from the dome follow
the path to the end. You will see three buttons. Each make the
same noise as the silver thing in Ghen's House. Push the right
buttons in the right order and move the lever on top on the
buttons. Catherine will talk to you and run off. Go back to
the dome and link back to Ghen's house. At Ghen's house go through
the book with five blocks.
Big Dome Island
Once out of the dome follow the
path to the end. Hit the button, get on the platform, and hit
the button again. Turn right once at the top and follow the
path outside and then through the building. When you reach the
door, lower the bridge with the lever and go across. Go through
the gold room and out the other side. Take a right down the
stairs to where you began. Go to the telescope thing and look
down at the manhole cover. Enter the combination from Catherine's
journal and pull the handle to open it. Remove the stop from
the left support column and flip the lever on the right down
and hit the button to lower the telescope as far as it will
go. Oops! Then watch the fun, you've won!
