One late night on a hill in Innsbruck, Doug struggled to organize his memories. He picked up the “present” which looked like a cross between an IPad and a giant Blackberry (whatever the hell those were). He only had one chance to recollect his memories and figure out the password. Apparently, the prize was astronomical.
That morning while walking back to his friends' place after purchasing a new towel, Doug had run into a group of 6 humanoid or at least mostly sapient tourists and their guide. After repeatedly muttering in confusion about how they shouldn’t be Doug’s problem, the guide introduced the 6 tourists and, for fun, organized a game for them and Doug. He also provided pendants and the password protected prize.
The rules were as follows:
The guide called ahead to buy them food and drinks at 3 different popular establishments where they would meet to play the game.
One of the tourists would be told the password before leaving earth without Doug hearing.
When the red button was pressed on an individuals pendant, it take them to one of the 3 meals or to the final meeting place. The meals were lunch at the Big Bang Burger Bar, dinner at Milliways, and after dinner drinks at some epic floating party. While Doug had to attend all three meals “in order” the others could control where they went.
None of the tourists could go anywhere except to the 3 meals until they went to the final meeting. Every tourist who attends a meal must meet all participants who attend that meal before leaving. They may not come back to a meal after they left it or went to the final meeting but they are not required to go to every meal.
At each meal, the current password holder would randomly select exactly one of the participating tourists at that meal who was not on his list of tourists who had already been told the password. He would then communicate the password to this participant along with his list of all past password holders. That new password holder would then go to a different meal and chose the next password holder unless he already knew this was impossible.
If someone successfully passed on the password, he would then be required to proceed directly from that meal to the last meeting place.
At the last meeting, the tourist who knew the password but had not told anyone would tell Doug the password. Any participating tourist who knew the password but had passed it on, would tell Doug a false password. Anyone who had never been told the password would not be allowed to speak to Doug.
A paradox occurs under one of the following (surprisingly lax) conditions:
Something made of matter exists at the same time as another version of itself (without certain safeguards which are not present in this puzzle)
Somethings occurs which prevents its own occurrence.
If a paradox occurs the entire universe in which the paradox occurs will cease to exist. This means that since we know Doug survived, anything that could happen that would result in a paradox simply won’t happen (thanks to a silly interpretation of the Copenhagen interpretation and the anthropic principle which should not extend outside of this made up reality).
Before leaving Earth, Doug learned the six tourists’ names: Thor, Zem, Gally, Emjay, Wowbagger, and Lintilla. Zem was used to demonstrate how to send someone off with the pendant. Finally, Doug caught Gally stealing his towel and he failed to get it back.
At the burger bar, Thor, Zem, and Emjay were in attendance. While Emjay was trying to ignore Zem gurgling constantly at him, Thor got violent about the lack of alcoholic beverages. Probably because Zem has fluff for brains and can’t remember the password on his own, Doug saw a scribbled up Janx Spirit napkin be put in a satchel made of Doug’s tied-up towel. When Doug tried to get the towel back, Emjay reprimanded him for trying to cheat. Emjay then sent Zem and the satchel off.
At Milliways, Thor, Gally, Lintilla, and Wowbagger were in attendance. Thor spent most of the night trying to get the attention of a cute raven haired girl he knew. She, however, did not seem to recognize or notice him. In order: they ate their meal; Thor left in a huff; Doug realized the table cloth Lintilla kept fiddling with was his towel; the tourists left; and Doug followed after them.
At the party all tourists arrived except Wowbagger. In order the following events occurred. Doug failed to get the satchel back from Zem as he couldn’t get through the crowd fast enough. Doug saw Thor meeting the girl from earlier; this somehow resulted in Thor walking out the door into midair. Killer robots destroyed the flying building. Doug witnessed Gally teleport away with his towel after failing to use it as a parachute. Doug finally remembered to use the pendant rather than go splat.
Doug only remembered 2 things from the final meeting.
- Everyone told him a password.
- Just before he passed out from the nausea (which he of course blamed on the shapeshifting room and time travel), Lintilla put Doug’s head on a pillow made from his folded up towel.
When Doug awoke, still ihebriated, he found the list of tourists and the passwords they said tucked into his towel pillow. Unfortunately the above events are all he can remember. Who was the person who told Doug the correct password?
