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.
Dubloon Disaster:
After a successful raid on Krawk Harbour, a small pirate ship tries to escape... but its crew didn't count on the most feared pirate ship of all, the Black Pawkeet, showing up to intercept them.
You play as Dorak, an enterprising young Krawk in a rowboat. Try to salvage as much of the treasure as possible, but avoid the homing mines that are being fired from the Black Pawkeet. Use the left and right arrow keys to turn, the up arrow key to accelerate, and the down arrow key to reverse.
