Rules:
- You have 10 seconds to find the place on the bottom of the screen
- You get an additional 10 seconds every time your answer is right
- Your time is decreased by 3 seconds every time your answer is wrong
- If the time is up the game will show you where you should've tapped. Try to remember the location so you'll know the answer next time
- Note that questions are meant to get gradually more difficult over time. Save as much time as you can in the beginning so you'll have more time to figure out the more difficult questions later

If you want to take a break or practice check out the Explore mode.
You can also check the current position of the International Space Station (ISS).
