Casino Reliability

 – 3 / 10

Blackjack-21 casino have a good reputation within the gambling community and we found no outstanding issues at any of the major casino complaint portals. As Blackjack-21 casino do not hold a UKGC license we have not sent a reviewer to test them.

Blackjack-21 Casino include a dormancy clause that we are not happy with and as such have been listed as Not Recommended. The term allows the casino to seize all funds if there is no activity on a player’s account for 180 consecutive days. Dormancy clauses should be used to allow the casino to charge a small maintenance fee for the upkeep of an inactive account, not to justify seizures of full balances. Exceptions to this would be where the balance seized would be transferred to the regulator for holding, or donated to a charitable institution after a period of a year, and only after reasonable efforts have been made to alert the account owner of the potential seizure.

Terms and Conditions are difficult to understand as they switch between small instances of German substitutions and poorly expressed English.

Only casinos carrying Deposit Guarantee Seal can score higher than 8/10.
