you're right - I wasn't very clear - so let me straighten that up a bit(posted 9431 days ago)Twin Galaxies sometimes does two types of high scores - one for a marathon, working on a person's stamina really - and another for a "tournament", working on a person's skill.
The marathon mode is usually default settings, with extra lives abound. The tournament mode is usually five lives, with one or no extras.
I hope that clears it up for you.
