I had no expectations from the weekly bonus of Shuffle. Because this is the first time I was eligible for the weekly bonus there. I have received only $3.1 from the bonus, which is actually 10% of the house edge. I had wagered around $3.2k within the last 7 days in their dice game. Looks like their weekly bonus calculation system is straight.

Shuffle team have sent a promotional email today. According, to the email, we are going to get the pre-monthly bonus twice in this month. There will be more bonuses from them in this month.
