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.
Extreme Herder 2:
Samrin and his beloved Petpets are back... but unfortunately so is Balthazar, and he's hungrier than ever! Can you help Samrin keep all of the Petpets out of the Lupe's clutches? Be careful, though -- if he can't get his paws on a Petpet, Balthazar might just have a Samrin-flavoured snack!
