This page lists all the endings of Nine Hours, Nine Persons, Nine Doors, and how to get each one.
About the Endings
To see the True Ending of the game, you must first see the Safe Ending.
The Coffin Ending
You can get the Coffin Ending if you have not seen the Safe Ending. The steps for the Coffin Ending are the same as the steps for the True Ending. Just make sure not to see the Safe Ending before following those steps. Once you see the Safe Ending and save the game, you won't be able to get the Coffin Ending.
The Safe Ending
To see the Safe Ending, choose door number 5 to go to the first class cabin, then after the casino choose door number 8 to go to the lab, then choose door number 6 to go to the steam engine room.
The True Ending
To see the True Ending, you have to have seen the Safe Ending (see above). After that, your save file will show the Safe Ending icon. The next time you play that save file, you can start from the beginning. In that playthrough, do the following things to see the True Ending:
After escaping from the Third Class Cabin (the first escape room), go through door 4 to reach the second class cabin, and take the bookmark from Santa.
In the kitchen, say that you think it's "rather odd" in response to what June says about CO2.
After that, go through door 7 to reach the operating room. While there, ask Seven if he knows about Ice-9. Later, give Clover the bookmark.
Afterward, go through door 1. If you did all of the things described in this section (get the bookmark, say it's "rather odd", ask Seven about Ice-9, and give Clover the bookmark), you will see the True Ending.
