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.
Wingoball:
It's the new game sensation that?s sweeping Neopia? WINGOBALL! The object of the game is to toss your wingoball so that it reaches the safety zone on the right side of the screen. Your ball is allowed to touch and bounce off of the various obstacles (bushes, potted plants, statues, etc.) on the field. Throughout the playing field, you'll find pesky little garden gnomes ? sometimes they stay in one place, but other times (when they think no one is looking), they'll move back and forth. If a red-hatted gnome snatches up your wingoball, you'll have to try again.
