Burning Investigations

• First the GM and preferably the players should have played Zendo.
  
• For any intent, if the appropriate task is an investigation (find the murderer, unlock the door, etc), you may begin the Investigation mechanics.
  
• To begin an Investigation,
  
  1. the GM (final authority) and players decide whether it will be Not A Big Deal/Standard/Big Deal
     
  2. the GM (final authority) and players decide how many secret sculptures the GM will build and how many rounds maximum the Investigation may take
     
  3. the players decide whether they want to do the Investigation given these decisions
     
  4. the GM secretly writes down a rule to classify sculptures as red or black (its difficulty guided by how big a deal it is), builds one sculpture marked red, and builds one sculpture marked black
     
  5. the GM secretly builds several sculptures to be used in the Big Reveal according to the agreed terms
     
• During an Investigation, any roll may be suggested by anyone to be an investigation roll. The GM has authority over which rolls are investigation rolls.
  
• An investigation roll is a roll like any other in BW - it has success and failure consequences. Additionally, if the roll succeeds, the player may either Guess the rule or build a sculpture and call Master or Mondo. If the roll fails, the GM builds a sculpture of his choice and calls either Master or Mondo.
  
• On any investigation roll, if the previous sculpture was a Mondo and the players guessed correctly, that roll is at +1D. If they guessed incorrectly, it is at +1 Ob. If the previous sculpture was a Master, the roll is not modified.
  
• Before any investigation roll with an intent orthogonal to the intent of the Investigation, a player may declare a Big Reveal in which they try to classify the GM's secret sculptures. Success gives +3/5/7D on this final investigation roll and success on the original Investigation intent. Failure gives +2/3/4 Ob on this final investigation roll and failure on the original Investigation intent. A Big Reveal ends the investigation, succeed or fail.
  
• Investigations break the Let It Ride rules in one key way. A player may have the same intent as the Investigation intent for an investigation roll, but upon success at the roll, that player must Guess rather than Master or Mondo, and the intent is not achieved unless the Guess is successful.
  
• Each Master, Mondo, Guess, and Big Reveal is one round of the Investigation. If the last round occurs without a Big Reveal or successful Guess, the players have failed at their Investigation intent.
  

Zendo actions:
-Master: GM classifies a built sculpture as red or black
-Mondo: Players guess which way a built sculpture will be classified, then GM classifies it
-Guess: Players guess a rule and the GM builds a counterexample or the Investigation intent succeeds.
-Big Reveal: GM reveals his secret sculptures and the players try to classify all of them. The player rolling has final authority over each guess. Once their guesses are made, the GM reveals the rule and classifies all of the sculptures. If the players were right on all guesses, they succeed, but if they were wrong on any, they fail.
