I am a bit confused with this bonus, do we unlock bonus money only with playing slots or it does not matter do we play bc originals, slots, or live casino? It's nice, but it's hard to wager a lot and unlock all bonus money, I guess this will be a long race!
I just searched for it and it is not so clearly stated. The only thing I can find is that you get BCD when depositing. You need to unlock this by wagering:
"Release amount = wager amount * game house edge * 20%". So based on this I think that the in-house games, the third party slots and the live casino count but not 100% sure.
