Winna seems to be related to Heybets.io
Winna.com is a relaunch/partner casino from Heybets.io which is a rogue casino!
As mentioned previously here this is either a relaunch of Heybets casino or new sister brand. Heybets is a very rogue casino that scams players and refuses to pay out winnings. I had a balance of 5K which they refused to pay out without explaining why, when I asked for a full refund (>8K) they did not respond.
Funny is that on June 10 I reached out to Heybets.io and they replied immediately asking for a KYC check with name WINNA. This confirms that Winna casino is either a relaunch or partner casino from Heybets which means they are up to NO good and likely will scam people too (something I can see with the negative reviews here already). It is also worth the mention that the excessive high positive reviews from users with only 1 or 2 reviews should be considered a red flag!
Be warned! Winna.com will treat you the same as Heybets did which means you will have no trouble in losing money with them but once you win money the story likely will change.
Of course if the casino management resolves this matter my review will be updated with the outcome.
