Hold your hand in the circle, or tap, to launch

1. Steer with your hand. Hold it inside the circle to hold course. Move it out of the circle and the tender goes that way.
2. Fly through the rings. Every ring you thread speeds you up. Miss one and you lose speed.
3. Answer with the sub. When a question comes up, drive through your answer: light blue ring on the left, purple on the right. Right answers are a big boost.
4. Go as far as you can. The Nautilus speeds up the whole time, and every wrong answer lets it close in. Your score is the distance you cover, plus 10 for every right answer.
