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.
Cloud Raiders:
It's your mission to pilot this flying ship from Faerieland to Terror Mountain. Sounds easy, right? Just another leisurely ride through Neopia's skies? Wrong! The skies above Neopia are full of danger -- from vicious enemies trying to knock you off-course to wicked tornadoes with enough power to splinter your ship!
As the ship's captain, it's up to you to guide your vessel safely to its destination. Set your course by creating a path of air currents for your ship to follow. Sail carefully -- if you crash, it'll be game over!
