Maybe this is another promotion depending on what you will avail since both of them needs to contact support to avail it.
I’m thinking you can avail both or the other promotion is already not available.
I also found it a bit confusing, so I took a look at their
help page to find an explanation. If I'm getting it right, then the reward table Panjul shared above is for users who joined the casino through their VIP transfer program. So only those users will be eligible for those rewards.
The other offer applies to all other regular users.
So, and I hope someone will correct me if I'm wrong, if you wager $250k and you've joined the casino via their VIP transfer program, you'll receive $1,750. Otherwise, you'll only get $1,000. I think the aim from this is to make the transfer program more appealing.
The most possible thing is that players can take only 1 reward because it will be very costly for the casino to give $1000 + $1750 for anyone who can wager 250k within 30 days.
Giving $1000 for players who can wager $250k is already a generous offer, I've never seen other casino offer such a big reward for that wager requirement.
So maybe you are right that the $1750 is for those who apply VIP transfer program while the $1000 is for those who have not (those who have no VIP account in other casino to be used to apply).
