MyStake Sister Sites

Who Operates MyStake Sister Sites?

GTW B.V. is listed as operator of MyStake and Donbet. Rolletto, Velobet, Cosmobet and GoldenBet are listed under Santeda International B.V. Both are Curaçao companies holding Curaçao Gaming Authority licences, so pages that name Santeda alone for every brand are out of date. None of the six brands holds UK Gambling Commission permission, so none is recommended to readers in Great Britain.

MyStake carries a safety rating of 9.7, labelled Very high, the top score in the group. Donbet, Cosmobet and Velobet all score 8.0 or above, while Rolletto and GoldenBet fall to 6.0 and 5.7, both below average. Scores vary within one operator, since Santeda brands range from 5.7 to 8.3. Another operator group is covered on the Pub Casino sister sites page.

How the Five Sisters Differ

Donbet

Donbet scores 8.4, the best of the five sisters and 1.3 below MyStake. It is the only sister listed under GTW B.V., the same operator as MyStake. No welcome offer is verified. It suits readers who want the sister that shares an operator with the main brand.

Cosmobet

Cosmobet scores 8.3, which is 1.4 below MyStake and a tenth behind Donbet. It runs under Santeda International B.V. No welcome offer is verified. It is the highest-rated Santeda brand, so it suits readers who want a High-rated sister outside the MyStake operator.

Velobet

Velobet scores 8.0, labelled High, which is 1.7 below MyStake. It completes the group of three sisters rated 8.0 or above. No welcome offer is verified. It sits 0.3 behind Cosmobet, so it suits readers who accept a slightly lower score from a Santeda brand.

Rolletto

Rolletto scores 6.0, labelled Below average, which is 3.7 below MyStake. Its terms are flagged for a dormant-account rule and a restricted-games rule. No welcome offer is verified. It is the second-lowest rated sister, 0.3 above GoldenBet, so it suits readers who read terms closely before registering anywhere.

GoldenBet
