The NP ratio tells you how many Neopoints you'll earn for every point you score while playing a game.
For example, if the NP ratio is 100 NP for every 150 game points scored, to earn the maximum 1,000 NP reward for playing, you'd have to score 1,500 points during the game.
On the other hand, if a game's NP ratio is 25 NP for every point scored, you'd only have to earn 40 points in the game to get the full 1,000 NP for playing.
Evil Fuzzles from Beyond the Stars:*KABOOM* *BANG* - Mutant Fuzzles are attacking the Virtupets Space Station!!! You play
Zygorax, a third class maintenance worker responsible for waste disposal... but instead of neocola cans
and juppie stalks, today you have to dispose of something far far scarier...
Hop inside your X-Scrub 4000 Walker Bot and patrol the outside of the space station, using your laser
cannons to shoot the enemies. Earn points for each kill, and spend these at the end of each level to upgrade
your walker.
