Are you guys motivated by BC.game? There are noticeable similarities of the UI and some other features between Coins.game and BC.game. BTW, there is an unresolved complaint on Casino Guru against your casino: "
Coins.Game Casino - Player's account was not closed promptly". I'm not sure whether the user had followed the self-exclusion process properly or not, but Coins.Game team should have cooperated with the mediator.
They also offer 100 no deposit free spins bonus by sign up but I'm not sure about the full terms for this free spins bonus, maybe you can try to find about it if you are interested.
We are required to make deposits to complete the 20× wagering requirements of the free spins winning. Overall, this isn't a 'no deposit bonus' actually.
