Credits cost way to much money. The game has good visuals and awesome concepts but if you can't play daily, I think it's a waste. After all 20 small purchases is better than 1 large purchase. I play several games that I make daily purchases in but those purchases don't exceed 5$ a day. And if I am not able to purchase at the very least, a full rounds worth of credits, for five dollars, I just don't make the purchase. I am not paying 10 to 20 dollars for one round of digital bingo.
