I haven't made deposits on Shuffle for a long while. My last deposit was two months ago. My PnL statistic is also negative there. So, my inactivity could be the reason for the exclusive bonus.
Actually your situation is almost the same as mine no deposit and negative PnL it's just that I'm active almost every day when claiming daily SHFL, yeah maybe this is one of the factors why I didn't get the offer. Once my SHFL fully claimed, I will probably be less active here because I don't have any other targets to pursue including VIP level, unless there is something interesting like a promo or something else.
Only one or two casinos have the base reward system for the weekly and monthly bonuses
Yeah I understand about this, and actually this so called VIP level is not so important here I mean there is no striking difference between one VIP and another VIP all purely based on wager maybe the only difference is in the percentage 5%-10% for each VIP level. This system is suitable for high rollers who have wagers of tens or hundreds of thousands every week while my wager are less than $1000 each month.
