You get points for being the fastest to submit the correct solution to a puzzle part each day. First one gets 100 points, second one 99, and so on down to place 100. So you could get up to 200 points per day if you solve both parts of the puzzle as first one. However unless you can be on your computer when the puzzles unlock (midnight EST (UTC-5)) I wouldn't bother with the global leaderboard, it gets filled within minutes.
