Fly Birdie through as many pipe gaps as you can without touching a pipe or the ground. One clean run, one score.
Every pipe you pass is one point. The scroll speed rises and the gaps slowly tighten the further you fly, so late pipes cost far more nerve than early ones. Clearing 10 pipes earns a bronze medal, 25 a silver, and 40 the gold. Your final score is the pipes cleared when you crash.
