I like how BC.Game engages returning players who've already spent some time with them. For example, I get SMS messages from them almost every week saying I can claim a new bonus code. Just yesterday, for instance, I received another notification offering up to $100. Unfortunately, I was lucky enough to get only $10, but still, I was left with a pleasant impression.
The only downside is that the wager requirements for these bonus codes are pretty much impossible to fulfill. I've never managed to transfer funds from the bonus account to the main one after meeting those requirements. But for playing just for fun, its actually a really nice option.
I usually get bonus offers by claiming codes via email, like yesterday but only today I had the chance to claim it, the amount is not big, only around $2, and at least this is enough to play actually to get rid of boredom.
I agree that the wager requirement is very difficult to achieve, but maybe 2-3 weeks before I was still able to get through it with the bonus offer, but remember that what will go into the main balance is the amount you get from the code, not the result of the game.
However, I like the way this casino interacts with its users, by randomly offering bonus codes personally, not on social media or telegrams which are quite impossible to claim
