## Play guide

Each action takes 9 seconds. You can view the details of the obtained items in the **Clue List**.

### Step 1: Obtain Keys and Passwords

First, the player must manage to find two small keys and a password hint sheet. To do this, it is necessary to proceed sequentially:

* Open the **Pot and Stove**, get **Small Key (Blue)** and **Screwdriver** (9s)
* Inspect the **Mirror**, get **Small Key (Red)** (9s)
* Inspect the **Bed**, get **Memo from Bed** (9s)
* Inspect the **Sink**, get **Note from Bulletin Board** and **Picture Frame** (9s)
* When having **Screwdriver** and **Picture Frame** simultaneously, they will be combined into **Picture of an Old Cruise Liner**.

### Step 2: Unlock the Briefcases

After obtaining the two keys and all the hints related to the briefcase passwords, the player needs to rearrange the symbols of different colors on the two notes according to the same color. After that, the correct 4-digit password can be obtained according to the numbers corresponding to the symbols on the password table.

In order to finish this:

* When having **Small Key (Blue)**, inspect the **Blue Briefcase** -> Input **0263**, get **Stack of Blue Key Cards** (9s)
* When having **Small Key (Red)**, inspect the **Red Briefcase** -> Input **7485**, get **Stack of Red Key Cards** (9s)

### Step 3: Combine the correct Digital Root. YOU FOUND IT!

After obtaining two sets of key cards, you can investigate the access control system next to Door 5. It requires the player to choose three numbers from the six numbers written in the key cards that can form a digital root 5 and input them. The correct answers are 1,6 and 7 (1+6+7=14, 1+4=5).

In order to finish this:

* Inspect the **Door 5**, input **1**, **6** and **7** to form a digital root of 5 (9s)

## Trivia

* The hints of the puzzle associated with the suitcase password always use the solid/hollow triangle symbol hints, which is used in the same level in the American version of *Zero Escape: Nine Hours Nine Persons Nine Doors*, whatever the current language is chosen in the game. While this hint in the Japanese version of *Zero Escape: 999* is shown with katakana characters. See here for details.
* The eye texture in the upper right of the interface that prompts Remaining Time uses the orange style displayed in Ryuki's Somnium.
* This bonus omits some operations in the original game:
	+ The curtain in front of the **Red Briefcase** does not need to be opened by the player;
	+ When getting some items that can be combined in the original game, the combination will automatically follow the acquisition of the second related item.
	+ The prop **Picture of an Old Cruise Liner** was shown as the front side by default in the original game, but here it is the back side. In the original game, players need to manually flip this prop to view the information on the back, but this operation is omitted here.
	+ After obtaining the file describing the digital root, Aiba reads the content directly. If you want to confirm again, you need to check it in the Log option.
	+ The password of the suitcase and the password to open the **Door 5** are all entered through the digital code pad, which is different from the original game.
