My wife has clicker trained our cats based on what she found on youtube videos. You need a smart cat (Ours are bengals) who loves treats and a lot of time but it's very doable. Our cats can both do the following tricks: Sit, Stand, High five, Turn around, Roll the ball, and Knock over the object

Training cats is in my experience more about actually forcing the cat into a position with your own hands to get it to grasp what you're trying to do.

Cats are not as magnetized to treats as dogs are, they tend to want to keep their feet at the same place.

That said: getting a cat to roll around on command is a great feeling.
