3. Rules & Examples
The Password Game

4. The Password Game
• Form an even number of teams (4-7 people)
In order to prevent passwords from being guessed,
User must be forced to create strong passwords
• In your team, invent 3 rules for what makes a valid password
• Keep the rules secret from other teams
• Be imaginative, have a bit of fun 
• Examples:
• “It must have an @ in it”
• “It must not be the name of a fruit”

5. The Password Game
• Create 3 examples (valid / invalid) that illustrate your rules
• Example:
apple
=> invalid
@pple
=> valid
tom@to
=> valid
• Pass your examples to another team next to yours
• Let them try to guess what your rules might be!

6. The Password Game
• Clarify with examples:
• As a guessing team, you can create new examples and ask them to be
checked by the team whose rules you’re trying to guess
• ONE example at a time
=> How many examples will it take to guess the rules correctly?

7. How was it?

11. Let’s try it!
Colin bought a kettle from us last week.
When he got home, he realized that the
color didn’t match his kitchen cabinets,
and it really bothered him.
So he has brought it back to the store for
a refund.
He walks up to Sally, a sales assistant, and
ask her to process the refund.
