It's been a while since anyone posted a skill, so I thought I'd throw something together.
Here's the old "guess the number" often used in programming classes. The player picks a number and Jibo tries to guess, with prompts from the player on whether he is high or low in his guess.
Just to spice it up, Jibo picks a random range for the player to pick within at the beginning of each round.
Please feel free to fork and expand. I would love to see what people come up with!
