Empty Cells must be delivered early, as a strategic move.

No robot is dominant enough to win by itself - good strategy can stop any 1 robot...if you're against 2 good once it's a different story.

Also, moon rocks tend to roll to the sides of the field, where they are harder to be picked by robots. A good strategy is just driving the whole way with one of your sides touching the side border, and this way you can easily gather 90% of those balls, in 10 seconds.
