Fun but not rewarding

I love this app, I really do but as one reviewer said you dont really get any big payouts. The people who are on the top of the leaderboards probably played for so long. Ive gotten almost 200 bingos and not once have I gotten even close to getting the max payout. When I get close it sits there and taunts me, for the one ball to come about when the score was 100 points regardless of what I play so.. Im not exactly impressed. And yet there are some people with scores like 134 billion.. Its a bit discouraging.
