I haven't downloaded BINGO but I did download New York Casino for 4,000 points (too tempting). They started me with $12.50 in my account. I played blackjack for 15 minutes got my account up to $22.50 then cashed out for a bank draft for $10.00 (that was the maximum I guessing because the $12.50 was there's to begin with).
I figured $10.00 for 15 minutes not bad. Plus 4,000 points!!!
