7th Door Walkthrough

(Please note that this walkthrough is a summarization of what several people have found out. There are also puzzles which change from game to game so that I'm not sure if every possibility is already in this walkthrough...)

1st room:
Switch off the light, write down the number on the door (it will be needed later on), and switch it on again.
One of the objects (changes in every game) unblocks the door. So click on the objects in the room until you hear a noise, then click on the door and enter 2nd room.

2nd room:
Switch off the light, write down again the number on the door, and switch it on again.
One of the objects (changes in every game) contains a telephone-number. So click on the objects in the room until you get the the number.
Click on telephone/fax and enter the number, you’ll get a fax. Click on the door and enter 3rd room.

3rd room:
Switch off the light, write down again the number on the door, and switch it on again.
Click 8 times on wall between the window and the picture. You’ll hear a noise, click on the door and enter 4th room.

4th room:
Switch off the light, write down again the number on the door, and switch it on again.
Click on the laptop and copy-paste one of the following answers (changes in every game)
利根川
信濃川
田沢湖

ナイル川
バイカル湖
グレー
トバリアリーフ
マリアナ海�
�

If you hear a noise, click on door and enter 5th room.

5th room:
Switch off the light, write down again the number on the door, and switch it on again.
Now add all the numbers you saw in the 5 rooms. Enter the result into the laptop.
Click on door and enter 6th room.

6th room:
Click on the picture on the left wall many many times… (I think I clicked on it 100 times or so).
When you hear a noise of the unblocked door, click on it and enter 7th room.

7th room:
Click on the chair (I’m not sure if object changes in every game…) and get 4 numbers.
Enter these numbers into the laptop.
Click on the light blue text on the laptop screen, it will open a Japanese page. On the top it says that there is a link on this page which leads you to the second code. If you examine the page using the tab key (you may also try to highlight the page), you will find a lot of links. Most of them take you to a page with a text like „end“, „wrong answer“ etc. There is only one link which gives you a historical puzzle, that means that you have to add or substract the years of two different historical events of Japan (again different in every game). So far there are following variations: 1972-692 / 1543+1932 / 1159+604 (maybe there are more…).
If you enter the correct number, you will get a number of two digits. Then switch off the light, you will see another number of 2 digits. These are the codes for the suitcase (you have to find out which number goes to which side).
Click then on suitcase and you will get a phone number. Click on telephone/fax and enter this number. You will get a fax with a message what you have to do to get out. In each version (also changes in every game), you have to click several times on one of the objects which are mentioned in the fax (e.g. chair, vase, painting, window…). So try and click up to 20 times on the objects…
When you hear the noise, click on the door and you are out.
