I think add also the price of the game if this is high rate if you buy copy or its high or low price..
I never heard that there is a multi game for black jack. this is unique if they release..
the question is what one understands under multi game for BJ
maybe OP can explain
It doesn't make sense. Everyone would want to play as the dealer, as the dealer as the edge (since they play second so player has higher risk of busting).
Or (based on the part about marketing), they are not actually playing as the dealer, they simply bring people to a table room (like poker) and collect a commission, however this doesn't seem plausible seeing as the site takes a 1% rake (making it sound like they do not supply the bankroll).
The most important question here is, who is supplying the bankroll? The site or the dealer?
I also highly, highly doubt that this product will have taken a total of nearly 3000 man hours. Are you seriously going to try and say your team will have put 5-6 months of work into this? The upwork part also has me on edge... I've dealt with several "highly rated" contractors from that site before and the work was atrocious (that was for $40-80 hr guys).
