Beginning to feel ripped off. I always use 4 cards and I'm constantly spending diamonds and real $ for power ups/more diamonds. Every time I use the "Instant Win" power up, I stop getting numbers that I can daub, let alone instant win numbers. Not to mention I won't use the Instant Win power up when there are less than 30 Bingos left because they magically disappear in a matter of seconds any time I do.
