Is casino bonus whoring easier than poker bonus whoring?

[Luzyfer]

I want to make a few hundred bucks extra to supplement my income without risking too much money and spending too much time. I have tried bonus whoring playing poker but I find most of them hard to clear at the micro level (low financial risk). For example, you have the dealt monthly bonuses at Crypto but to clear $100 in 5 hours you need to play 2/4 Limit on 4 tables (100MPPS/hour). Another "easy" one is Will Hill´s but you need to sit for 5 hours at 1/2 to get $50. A similar thing happens with the Prima ones (Eurolinx, Purple). Most of the times I just broken even after the bonuses were cleared.

A good bonus for example is Empire´s 10xRHs. You can clear it at the micros in 2-3 hours (low financial risk plus clears fast). After looking around I see that this could probably be the only poker bonus of this nature. I want to dig into the casino bonuses and see if with some basic blackjack skills (or any casino games if possible) I could clear some good bonuses. Any Empire´s like casino bonuses around that I could clear relatively fast (no more than 4 hours per bonus) and playing for pennies?
