Just finished riven for the second time.
Marble puzzle riven.
And here is a view of the plaque from a few steps back with the catwalk retracted to match the diagram.
These two core puzzles are the tombstone puzzle and the fire marble puzzle.
That said i noticed a design flaw in one part of the fire marble puzzle.
In riven two core puzzles need to be solved to complete the game.
If you are really stuck here is the solution.
There is a mistake in this diagram.
Here it is annotated.
Marble puzzle solution once completed successfully this will restore the power to all the fire marble domes around riven.
Open the star fissure before visiting gehn or catherine.
If you have solved the puzzle you should hear the system powering up the linking books and see the marbles ending back on the right.
If not the marbles stay where they are and you need to try again.
A number of minor puzzles must be solved to access these clues.
Visit gehn and capture him in the trap book and go back and open the star fissure without freeing catherine.
On riven the number system and the letter system are based on the power of five so the six symbol colour system really stands out.
After solving the fire marble puzzle there are other ways to end the game.
Open any of the marble domes and enter the 5 d ni numbers you have obtained from gehn s book these are always different therefore if you have not obtained these you will need to go back to his lab on crater island and.
Here it is by the way.
Visit gehn an do not capture him and do not free catherine but go directly back and open the star fissure.
Others change randomly each time the game is played so they have to be discovered during gameplay.
Each puzzle requires a significant amount of time spent in detailed study of various clues provided in the game.
As to the marble puzzle the solution lies in the colour of the grand dome.
Since a most of riven s puzzles are based on the exploration of the world there are only a few direct solutions.
It is now time to leave the riven islands.
One of my favourites.
