Mine is Shenkuu Warrior - so easy to make 3k in about five minutes. I think it's fun too, but it can get very frustrating when you're going for the high scores.
I actually like ceelblock because I got the gold trophy all on my own. Also, destruct o match II and chemistry for begginers.
i like whack a kass too. especially when you know there's more to just pressing spacebar when the kass comes.
Destructo Match, Shenkuu Warrior, Meerca Chase, turmac roll, peanut dash are really easy to get points on. I think Shenkuu Warrior is the best too.
Whack a kass if your talking about 3k in short time...one minute is all i need. kinda fun too...kinda. I like suteks tomb for enjoyment.
I can't play Whack-a-Kass. XD; And even if I do, the most I earn from it is about 300np per game. In the past anyways.
