I will repeat once again that I am an active gambler and have tried many crypto casinos.
Won stake.com 26k and 23k this summer (withdrawals received in minutes, no KYC and or additional reports)
Won 6k on Bitsler.com this March, paid out in a few minutes
In same month of March, 6k was won on duelbits.com with sports betting (7 days need wait until confirmed by KYC, but after confirmation winnings were paid out)
Also, this year I won twice in BC.game, first win 26k, next 28k (both wins paid within 12 hours, no KYC and no account locks)
with BC.game already had a situation when we were waiting for a response from the game provider and whole process did not take more than 12 hours.
And OWL.games presents itself as number 1 WEB 3.0 casino, their token is stable, so I don't really understand why I shouldn't play in such a casino?
This kind of investigation typically take some time not just because they are waiting for the provider response but also they are doing some careful analysis on your case. The amount involved is not just a penny so it's normal for the casino to have a slow response. You can check how other reputable casino timeline on handling this case. Some take months or more for a case to have a clear result since you are not the only customer that they are handling.
Be patient. Forum members is on your side in case Owl didn't provide a satisfying explanation.
