Just realized that metawin has an original game. It's been a long time since I played here. But I'm also curious why I haven't received a referral bonus even though my referrals have wager more than $10k, it seems like the referral wager calculation is not transparent and there are no live statistics
But I like your UI, it's nice to look at.
Have you reviewed the referral terms found on:
https://metawin.com/referrals/?For instance there is a 30 day cooling off period and payouts are sent at the first week of the month thus, make sure the dates are aligned. It's possible some may have been flagged, too.
Ultimately, your best bet is to get in touch with support to get a better idea. I don't think we could help much.
Good luck!
