A blogpost about how I use this game: [url]http://mathhombre.blogspot.com/2012/05/guess-my-rule.html[/url]
A guessing game!
The computer knows a rule. When you tell it a number, it will multiply it, and then add to it.
The computer will tell you the output.
Can you guess the rule?
What's the smallest number of tries you can get?
