Hello everyone,
I’ve just seen this thread and wanted to respond. We appreciate discussions around transparency and fair play, as these are core principles for us. However, I do not agree with the way some of these technical points are being presented in a manner that implies malicious intent on our side. It is worth noting that competitive dynamics in the crypto casino space can sometimes influence how these discussions emerge. Nevertheless, we prefer to focus on the technical aspects and verifiable facts.
The Winna Originals fairness system has never been tampered with, and every game result has always been generated fully randomly.
-- Winna's server seed hashing implementation is not provable, or provably fair.
The previous implementation used HMAC-SHA256 to generate the server seed hash. We have now migrated to using a simple SHA256 hash to align with the implementations used by platforms such as Stake or Shuffle.
It is important to clarify that the hashing algorithm itself does not determine the fairness of the system. The purpose of the hash is to commit to the server seed before gameplay begins. Provable fairness is achieved through the combination of the server seed, client seed, and nonce, which together determine the final game result. As long as the server seed is revealed after the seed rotation and matches the previously published hash, users can independently verify that outcomes were generated correctly. Using HMAC-SHA256 instead of SHA256 therefore had no impact on the randomness or fairness of the seed pair.
-- Winna's zero-bet nonce disuse is suspicious and the code being used in the backend should be audited by a third party, as all steps are not externally repeatable.
This point is somewhat more complex. We are still working on properly addressing $0 bets, as doing so requires changes to how these bets are stored and how the seed incrementing process is handled internally. These adjustments involve larger architectural changes, but we expect this to be implemented by early Q2 2026.
Our backend has already undergone an in-depth audit previously. Most recently, the system was tested in 2025 by Cyrex Enterprise (cyrexenterprise.com). In addition, we are planning to open-source the Originals codebase in Q2 2026 and have the games independently tested again so the results can be published publicly.
-- Winna not allowing you to pick your own client seed is a clear violation of standard provable fairness practices.
This has already been addressed. Users are now able to choose their own client seed on Winna.
-- Winna's laggy originals imply excessive processing in the backend, or highly unoptimized code.
Since we are one of the few casinos that build all Originals fully in-house rather than relying on third-party providers, some performance issues occurred as a result of the rapid growth we have experienced over the past period. These issues have already been partially addressed, and our team is continuing to improve performance further in the coming months.
-- Winna has ties to a recent rug which is clear from even minor snooping in the DNS and page designs/structure.
We have publicly stated before that we have no connection to this site, and that remains the case.
-- Some questionable affiliate practices which are not the core of this complaint.
Without further details, this appears to be an unsupported claim. I would appreciate more information so that we can properly review and address any concerns.
Anyone is welcome to independently verify game outcomes through the provably fair system. The purpose of this system is precisely to allow users to reproduce results and confirm that no manipulation has occurred.
Transparency and trust are important to us, and we will continue improving our systems and sharing more information as we move forward.
