Pull up a chair!
Pick a desk and coach that student from your phone. Tap the notebook to teach it something, then send it off to study. Empty desks get a robot tutor. Every result goes in the Hall of Fame forever.
Every match ever played counts. The number under each name is a rating that goes up when your student beats the others. Nothing is ever reset.
Four teachers. Four little students. One big exam.
Every student starts out knowing nothing, and they all start exactly alike. Each one has to learn the same secret rule: which spots are a “yes” and which are a “no” .
There are 10 rounds, with 15 lessons in each. Tap anywhere in your student's notebook and the classroom tells it the right answer for that spot. A raised hand means your student is unsure about that spot, and answering those questions often helps the most!
When you're done, press Study time! Your student studies everything you've taught so far and redraws its guess line.
After round 10, every student takes a secret 5,000-question exam. The best student wins 
, and the top three go on the podium.
A new match starts every few minutes, day and night. If your phone drops out during a match, your student just waits until you're back.
