One of the things I like about bingo blitz is how they incorporate the dynamics of the various rewards, with the slots, bingo, the monkey minis in the waiting rooms, and the various venues they offer to bounce around juggling the rewards with game play. If for example, by happenstance, by some glitch, I was presented with thousands of credits... I wouldn't call the game people and demand they take it back...it's just virtual credit for a virtual game. I would consider it was a mistake. But I would also consider that it was just a wonderful surprise put out there by the game creators for the ambitious or lucky players that happened upon those secret caches of credits. I would not put it beyond their creativity and\or generosity. I've been very pleased with how the game play is not overly stingy, example; treasure chests in cantalina, mini monkey bets.
