How I know they are connected
Listed by independent casino directories. Each point below is backed by a source listed at the end of the page.
- Casino directories list Red Stag, Uptown Aces and Slots Capital under Deckmedia N.V., a Curaçao company. The same listings include Sloto'Cash, Miami Club, Uptown Pokies and Fair Go.
- Deckmedia is listed as holding a Curaçao master-licence sublicence. The licence number I could confirm on one of its sites is 1668/JAZ.
- Red Stag and Uptown Aces state the same crypto payout time (up to 4 business days), which is consistent with a shared cashier.
Why sister sites matter to you
Sites in the same group usually share a cashier, a support team and a player database. In practice:
- Problems travel. If one site is slow to pay or quick to void bonuses, its sister sites tend to behave the same way. Judge the group, not just the logo.
- One bonus, one person. Group terms often limit welcome bonuses to one account per person, household or IP address across all sister sites.
- Closures and self-exclusion carry over. A ban or self-exclusion at one site can apply across the group.
- Switching rarely solves a dispute. If your withdrawal is stuck, opening an account at a sister site will not speed it up.
