Hah! You think you can do it without the help from those little tiny icons? Well it's pretty darn hard to do so. But here take these steps and You'll do fine.
1. At start of game you have the *big* ball power and the *triple* ball power.
2. When you bowl, line up in the middle
3. Go full speed down the middle, and if you see a blue star use your triple ball, and if yellow you should use the big ball. And if there is both, well then use both.
4. This wil lallow you to get unlimited strikes because in my opinion these are the two best ball powers in this game.
5. keep doing this every time to get a perfect score!
