ROLES

Two police officers; two suspects  

*Colors include that of the 2 police officers’

DURATION

15 minutes

RULES

1. The police officers win if they correctly identify both suspects (the right color, shape, and alphabet combination). Unless both suspects are identified; however, the rest of the class wins

2. First off, the police officer should try to identify everyone’s color, shape, and alphabet first. I will give the police 3 related hints when there are 5 minutes left in the game. 

3. The police officers can ONLY ask, are you [shape] and [alphabet]? They can ask whomever they want, however many times they want, but they cannot fixate on the same person with consecutive questions, as that would be considered police harassment. 

4. Non-police officers can only answer “YES” or “NO.” Please do NOT reveal your identity to either the police or each other. Protect your identity and keep it to yourself!

• YES if the officers get either the shape or alphabet right, but do NOT specify which the officer got right
• NO if the officers get both the shape and alphabet wrong

5. Each police officer gets to officially guess twice by the end of the game. You are out of the game if you are accused by either of the officers as a suspect, even if you are wrongly accused

·      Please return your piece of paper to Dr. Lee, without revealing your true identity to anyone, if you are (a) eliminated as a potential suspect by both officers or (b) if you are identified as a suspect, even if you’re wrongly accused
