The level up bonus looks great, the silver-gold1 for example which requires less than $100k wager and receive $180 total reward. Something bigger than offered by most other casinos if I can remember it correctly. Although it applies for 1 month only but it is still a nice offer. Of course it is not something to chase by players because if we force ourselves to chase the bonus only, it will not worth the risk and we may lose more than what we get from the reward.
I don't think they are supposed to be "worth" the spending, but a nominal bonus. I am not even sure how much it would should be that would make it worth for only.
Or they could do multiple freerolls for Wood, Bronze, and Silver in one tournament that gives one seat in the VIP tournament. Then have another freeroll for Gold and Platinum that gives the top three finishers of that tournament three seats in the VIP tournament.
They could also make a schedule. One monthly VIP tournament, with two or three freerolls per week to give opportunities for lower-ranked users to enter the VIP tournament.
Excellent ideas! Although organizing poker events could be more work, even if just monthly, it sill would be pretty cheap and effective advertising.
It would be even more relevant and effective if they had plans to offer player vs player poker tournaments inside the casino, but we can't have everything.
