Yes, the bonus amount is the same as it was the last time, around $10.
Those type bonus, always have the same amount.
No mater about some important event, new games bonus or other. My claim for my rank is always like you, which is 10$.... I believe we can't earn more cause these kinds of amount got fixed amount by our VIP Rank & could be waggering to qualified for the bonus.
Just my two cent.
