Donbet Sister Sites

Who Runs Donbet Sister Sites?

GTW B.V. operates Donbet and MyStake, which makes MyStake the one sister on the same operator. Rolletto, Velobet, Cosmobet and GoldenBet run under Santeda International B.V. Earlier pages name Santeda for Donbet as well, so the group has operated as one network under two company names. None of the six has UK Gambling Commission permission, so this page recommends no brand to readers in Great Britain.

Donbet scores 8.4, labelled High, behind only MyStake at 9.7. It trails MyStake by 1.3 but leads Rolletto and GoldenBet by more than two points. Another operator group is covered on the Pub Casino sister sites page.

What Sets Each Sister Apart

MyStake

MyStake shares Donbet's operator and carries the group's top safety rating at 9.7, labelled Very high, which is 1.3 above Donbet. No welcome offer is verified. It suits readers who want the same-operator sister and the strongest score in the whole network.

Cosmobet

Cosmobet scores 8.3, labelled High, just 0.1 below Donbet. It runs under Santeda International B.V., a different company from Donbet's operator. No welcome offer is verified. It suits readers who want a near-identical score from the second operator.

Velobet

Velobet scores 8.0, labelled High, which is 0.4 below Donbet and 0.3 below Cosmobet. It also runs under Santeda and completes the three brands in the High band. No welcome offer is verified. It suits readers who accept a slightly lower score.

Rolletto

Rolletto scores 6.0, labelled Below average, which is 2.4 below Donbet. Its terms are flagged for a dormant-account rule and a restricted-games rule. No welcome offer is verified. It suits readers who read terms closely before registering anywhere.

GoldenBet

GoldenBet has the lowest rating in the group at 5.7, labelled Below average, which is 2.7 below Donbet. It runs under the same Santeda licence as Cosmobet, which scores 2.6 points higher. No welcome offer is verified. It suits readers checking the weakest sister.

Picking a Sister Over Donbet

Donbet's own record is the benchmark. Readers who want a higher score than Donbet have one option, MyStake. Readers who want the same band have Cosmobet and Velobet. Rolletto and GoldenBet score more than two points lower, so they are the weakest matches.
