Super Monkey Ball DX
Aaah this game brings back memories...I got it when I was 5 and still play it CONSTANTLY to this day. Super fun, challenging levels, awesome minigames, you can't really beat this classic game!
The game was fun. On the other monkey balls there were only about 150 levels- on this there are over 300! Beginner is a little easy, but I'd recommend starting there even if you are experienced. Advanced is not too hard until level 18. I like beginner more because there are less levels- plus it's easier. I have only tried expert a few times, but it was too hard- I could not get past level 3. After awhile of playing the sound gets annoying, but there are ways to turn he sound off. Out of all the monkey balls this is the best!
