Four random shots are flashing green, and the other four are flashing orange.

First, you need to collect pitch (green shots).

Then, you can start fires (orange shots) which score 2,000,000 points.

If you start all four fires, you score a bonus 4,000,000 points and all shots turn back on.

Remember: You can collect more green shots than orange, but you cannot collect more orange shots than green.
