A story on paper:60

[The Abacus]

Examine the walls.

[The Kakama]

Examine the walls.

Left wall: Already examined(the one with the panels)
Front wall:
There's a small plastic tag on the handle.
Right wall:
There is a panel on the wall.
There is no back wall, because it leads to the elevator you came from.

[The Abacus]

And the left wall is the one with the coloured panels?

Examine plastic tag and panel.

[The Kakama]

And the left wall is the one with the coloured panels?

Yes.

Examine plastic tag and panel.

You see that the plastic tag says "Top to bottom/ telephone"
Snarr takes a look at the panel:

There is a smaller panel on the panel, which could be opened by hand.

[The Abacus]

Open the panel on the panel and hope it doesn't reveal another panel.

[The Kakama]

Open the panel on the panel and hope it doesn't reveal another panel.

Snarr opens the panel on the panel and finds... a number pad.
It's written in the universal numeric symbols, ie. Snarr understands what's on it.

[The Abacus]

attempt recollection (try to remember the code)

[The Kakama]

attempt recollection (try to remember the code)

No, none of you remember any (more, in Snarr's case) codes.
Snarr: I think all we need to open the door is in the room.
60: Hmm, all we have in the room is a string of colours, a tag that says "top to bottom, telephone", and a number pad.

[The Abacus]

Try 147258369. (I have a feeling that this won't work)

[The Kakama]

Snarr tries it and... it doesn't work.
