Why do lists of MyStake sister sites disagree?
MyStake’s older customer agreement names Santeda International B.V. alongside Donbet. That explains historical comparisons with Rolletto, Cosmobet and Goldenbet. Later published domain records and operator reports associate MyStake with GTW B.V., while the Santeda group continues to appear separately. The older agreement cannot establish that every previous sister relationship remains current.
Shared software and familiar game categories do not resolve a changed contracting company. Nor does an international group connection establish a UK casino roster. The available evidence does not support five British sisters with current UK welcome terms, and an offer from a former affiliate of the group cannot be treated as available through a MyStake account.
MyStake groups several gambling products together, without establishing any shared balance with another casino.
Rolletto is repeatedly linked with MyStake in independent research, but its current account rules must be checked separately.

Frequently asked questions
Can I use my MyStake login at Rolletto?
No shared-login entitlement is established. Their historical group connection is not an instruction to reuse credentials. An existing MyStake account should be managed through its recognised account channel, not another casino’s sign-in page.
Is MyStake’s old Santeda agreement still proof of ownership?
It establishes what that document says, not necessarily today’s operator. A later company change can make an old family list inaccurate even when the casino retains its name and familiar interface.
Does a new MyStake address reset welcome eligibility?
No automatic reset follows from a domain change. Account history remains relevant. A different spelling or numbered address is not evidence that the operator considers an existing member a new customer.
