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.
The Return of the Return of Dr.Sloth:
Dr. Sloth is back yet again, and this time he's unleashing a barrage of battleships upon Kreludor
and Neopia's outer planets. Take control of your own space jet and defend the planets against Sloth's
evil invaders by blasting them out of the sky!
NOTE - This game may run slowly on older computers. Sloth deems you too weak to play and you
shall be eliminated shortly.
