### Zendo (adapted for the forum) -- Game 4 (BNLP's) running!

Posted: Thu Jul 12, 2018 4:13 pm
Welcome to Zendo, the inductive logic game! Well, at least, a form of Zendo created for this forum.
Note that we are playing slightly differently from https://boardgamegeek.com/boardgame/6830/zendo because forum play is better done asynchronously (i.e. not turn-based).

Game 4, run by BulletNLynchproof: viewtopic.php?f=91&t=77047

Note
Starting with game 3, all games will be run in Frogstar World B. This allows multiple games to be run simultaneously and clears up the main thread for organization and general discussion.

Overview
In this game, you will be trying to figure out a secret pattern before anyone else does. You will ask if specific strings follow the pattern and earn guessing points to try to figure out the final rule. Only one can win!
(Instead of structures of blocks, this game will use strings of letters restricted to the letters "A", "B", "C", and "D". (E.g. ABAC, A, AAAAA, BDDC, etc.) Maximum length is 10. I considered other options but decided to keep it simple for this one.)

Gameplay
This game will be played asynchronously, in contrast to the original which is played in turns.
At any time*, you may post one string of 1-10 letters that contains only the letters "A", "B", "C", and "D". (Case is irrelevant, but please be consistent.) You will also write either Tell or Quiz.
If you write Tell, then when I come online, I will indicate whether your string does or does not follow the pattern.
If you write Quiz, then ALL players, including yourself, will have 48 hours to guess whether your string follows the rule or not. Send a PM to me, and when 48 hours have elapsed, I will reveal every player's guess and the truth. Everyone who was correct receives 1 guessing point.

Also you may at any point* submit a Final Guess to attempt to guess the pattern. This costs 1 guessing point. Post publicly what you believe the secret rule to be.
If you are not completely correct, then I will post a counter-example, which will either be (1) a string that follows your pattern but not mine, or (2) a string that follows mine but not yours. (In other words, a string that our rules would mark differently.)
If you are completely correct (and you were the first to be such), then you win. Note that equivalent rules stated differently still count. (E.g. "It must be completely composed of A's and C's" is a correct guess for "There are no B's").
I reserve the right to reject a Final Guess if it is vague ("There must be a C" -- at least one, or exactly one?) or if it is clearly a troll guess ("If [insert unsolved math problem here] is true then the string must have an A, otherwise it must have a B"). If it is an honest mistake, then you will not lose a guessing point.

(Just to be super clear, Final Guesses are about the entire rule, and cost 1 GP, whereas Quiz guesses are about one particular string, and may or may not earn you 1 GP.)

*Except for...
Rate Limiting
You may not submit two strings within the span of 24 hours, nor can you submit a Final Guess within 24 hours of submitting a string or another Final Guess.
(Yes, you may submit strings while you wait on a Quiz to complete.)

Activity
You can join simply by posting strings and exit simply by stopping. The only rule on this is that you cannot make a Final Guess if you have not submitted a string in the last five days. (This gives people advance warning if you decide to come back, so you cannot just win the game out of nowhere.)

Other Rules
Reserved colors: Red, for strings that do not follow the rule; Green, for strings that do; and Blue, for guessing points.
No outside discussion if the game is ongoing.
Follow all site rules. You know that.
You can discuss the game inside the thread, although given that the game is competitive, you may not want to.

Here are some rules that I must follow:
> The order of the letters in the string may or may not be important.
> The rule depends ONLY on the string. Strings are NOT case-sensitive. Also, it does not depend on the time or order of posts, the user that posted it, whether you chose quiz or tell, or anything else outside of the string itself. (Those troll find-the-rule games are great, but not what I am doing here.)
> I will, at the start, post one string that follows the rule and one that does not.

Example GameHere is an example of a complete game. It is very long, so it has been spoilerified. The rule is at the end. The mod repeats the players' Final Guesses purely out of clarity; their guesses were posted publicly.
Spoiler: Game
Player 1 posts "CBC, Tell".
Player 2 posts "AAA, Tell".
Moderator posts: "CBC is red. AAA is green."
Player 3 posts "CCC, Quiz".
All players PM the mod their guesses. 1 sends Yes, and 2 and 3 send No.
Player 2 posts "B, Tell".
Moderator posts:
> B is red. CCC is red.
> CCC: Player 1 was incorrect. Player 2 and Player 3 were correct, they each receive 1 guessing point!
Player 3 posts "AC, Tell".
Moderator posts: "A is green."
Player 3 posts a Final Guess: "There must be at least one A."
Moderator posts:
> Player 3's guess, "There must be at least one A", is incorrect.
> AB is red, but the guess would mark it green.
Player 1 posts: "AABB, Tell".
Moderator posts: "AABB is red."
Player 3 posts: "ABCB, Tell".
Player 2 posts: "ACCC, Quiz". 1 and 3 guess Yes, 2 guesses No.
Moderator posts:
> ABCB is red. ACCC is green.
> ACCC: Player 2 was incorrect. Players 1 and 3 were correct, they each receive 1 guessing point!
Everyone has 1 GP.
Player 2 posts a Final Guess: "There must be at least one A, and no B's."
Moderator posts:
> Player 2's guess, "There must be at least one A, and no B's", is incorrect.
> AAABBC is green, but the guess would mark it red.
Player 2 leaves the game.
Player 1 posts: "AAB, Quiz". Both players predict No.
Player 4 joins the game and predicts No.
Moderator posts:
> AAB is green.
> AAB: All players were incorrect.
Player 1 posts a Final Guess. (It ends up being correct. I am not writing it here in case you want to figure out the rule for yourself.)
Morderator posts:
> Player 1's guess, [REDACTED], is CORRECT!
> Congratulations, you won!

Spoiler: Rule
There must be strictly more A's than B's.
(This ended up being one of those rules where the order of the letters did not matter. However, in general, you do not know that.

CBBCCB QUIZ

(if you aren't being strict about the 24-hour rule, obviously)

Posted: Fri Jul 13, 2018 1:00 pm
Eh, I think we need a quiz going, so I will allow it for this time.

Everyone (including skitter30) please send me a PM of whether you think CBBCCB follows my rule or not.
