All the Bloons games offer a lot of easy AP. SAS 3 offers 50 when you first play it. You can also try and earn some NK Coins by doing surveys, etc. to purchase Premium Upgrades, which will allow you an easier time in those games. There are also other NK games which are slightly more difficult. Needless to say, they also some decent Awesome to earn.
 * BTD5 (lots of AP)
 * BTD4 (quite easy to complete, purchasing Premiums not recommended)
 * BTD Battles (easy to complete except for Unspoppable, purchasing Premiums not recommended)
 * Bloons Monkey City (lots of AP, purchasing Premiums not recommended)
 * Bloons Super Monkey 2 (requires lots of farming, purchasing Premiums not recommended)
