I love it, and I found a loophole on how to claim less than 10 rewards at a time. The loophole is is to close the icon in the middle of the whole thing.
Could you think up an idea of giving free shop offers every 100 day streak on Daily Bonus? So, you could give this reward on days 100, 200, 300, 400, 500, etc.
Actually, there is a series of Bubble Witch. However, this means that a game is older than even Bubble Witch 2 Saga. It´s called Bubble Witch Saga, but will be no longer available by October 2.
