Up Your CardI did the challenge Pogo gave us for Casino Island Blackjack: Use an Up Your Card bonus 8 times. It didn't even take me that long. Then I went to purchase with my Pogo Gems another Mix-N-Match challenge for Casino Island Blackjack: Get a score of 19 or higher 25 times. I got it so fast and was shocked how many Up Your Card bonuses and No Bust bonuses I got.
I bet with the max number of tokens 50, and in Blackjack Carnival, I bet with the max number of tokens 250. I just don't use any of the side bets in BC cause it's cheap but costly if you don't win it.
