K, this is what I found out, vp is allowed, the extra tc bonus is not multiplied and the limit is 5000tc. I am diamond so my conversion rate is 1.75 /1$. I have played bad game becoz they earn 1tc for $10. So looks like I will make some money provided I run good on 8/5 aces and faces, which is the game I will play. Next time if I get this offer, i will play low variance slot machines like cashmen
