I have finally won my first zingoz pop trophy thanks to all the help I received from the tutorial. At the end I just kept thinking about not connecting the balls and knowing where to place them. Thanks to everyone here for your help!
Congratulations! Now you can start stacking them up! And stacking up the KC as well.
I lost count of mine since I play in various accounts and they are spread around (it is such a cute trophy!). And I don't have as many as some of the folks here -- but I'd say 60 or 70. Once you win it, it becomes easier to again.
