As with any application, you're supposed to have testers run through it. Typically with any application you need 3 to 5 testers, more just usually gets you duplicates, less doesn't get you enough responses. It often helps to see how they interact, but the fact remains, you want playtesters to try the game and tell you what they think of the experience and what they like or don't like.
