Weekly promotion or bonuses is what I like and what's on my mind is something like a rake back or free bet depending on how much you wager on that week and of course you should have a wagering requirement as many user would probably take advantage on that kind of bonus considering that it is a weekly bonus.
All the types of bonuses that you mentioned are what we usually see in several casinos here and the purpose of the Op in making this thread is to get weekly or monthly bonus recommendations that are different from other casinos.
Like for example giving weekly or monthly bonuses with a higher percentage than other casinos.
For example, certain casinos provide a weekly bonus of 1% of the total bet and new casinos provide a weekly bonus of 4% of the total bet, this is what makes the casino look unique, attractive and different from other casinos.
