As you would expect, the first few levels are simple and easy. The game starts getting more interesting at level 6. Here are a few hints for playing:
- When you put your mouse over the ball and the targeting arrow appears, move the mouse cursor to the tip of the arrow. You can aim more precisely that way.
- When you put a ball in the wrong color bucket it gets shot back out. You will want to remember that for solving some levels.
- You can use the restart button to start a level over. I had to do that when I managed to get two wrong color balls in the same bucket and they were stuck.
