1. Turn the sound on. 2. Click space bar to start (but you still have to click the green flag first). 3. Help the apple (the tiny red dot at the left of the screen) to Taj Mahal (the white marble building in the introduction's background and the small building in the right corner. 4. Try not to hit the yellow line! If you do, the apple will go back to its first position. 5. Enjoy!
