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.
Kid Cuisine KC Space Excavation (Ad):
KC's Galactic Pack held all of his planetary postcards, but somehow, anti-gravity got a hold of them and now they are scattered across the galaxy! Unfortunately, they are all hidden behind walls of space debris, and now KC must dig them out in order to return them to the Galactic Pack. Can you help him?
