13 weeks after our request for data, Winna has published its side. We’ve reviewed it independently; here’s what the evidence shows, so players can judge for themselves.
- Our verdict is unchanged: on the evidence supplied, Slide VIP was NOT provably fair.
-That is not a finding that results were manipulated. Winna’s numbers in the evidence package add up; what’s missing is independently verifiable evidence of how each round’s seed was chosen.
WHAT WINNA'S DATA SHOWS
We independently recalculated all 13,125 rounds Winna published, and every result matches its seed. The betting records Winna supplied cover only this player, and his 62 bets agree with the records we examined earlier. Results across the whole game are consistent with the stated formula for a 98% theoretical return.
So the round data adds up. But it only shows that each seed produces its result, not how each seed was chosen. Winna also didn’t publish the full list of the player’s target multipliers, so some of its probability figures, including its estimated 1 in 107 chance of a loss at least this large, can’t be independently reproduced from the provided package.
WHAT'S MISSING
Winna says each round used the next seed from a pool of 10 million, created in one batch. The package doesn’t include that original pool, the record of its creation or independent proof of the order in which the seeds were used. What it provides is a record of the 13,125 rounds, published after the fact.
Each Slide VIP result combined Winna’s secret server seed with a client seed. That client seed never changed: it was the hash of Bitcoin block 779,588, public since March 2023.
Because the client seed was already known, each server seed’s result could be calculated the moment the seed was created, before it was assigned to a round. In principle, that would let seeds be picked for their results, and every check above would still pass.
Winna says each round’s hash, a one way fingerprint of its seed, was shown when the round opened. A real pre bet hash stops a seed being swapped after it’s shown. It doesn’t show that the seed was picked fairly in the first place, or that it was really the next one in the pool. We have not seen verifiable proof that those hashes reached the player before he bet.
HOW IT SHOULD WORK
Winna’s own public Slide shows the right way to do it. It launched on 18 May, while Slide VIP was still running, using this design:
A hash chain: 1 secret seed is hashed ten million times over, and only the last hash is published, as the anchor.
Play then runs backwards: each round’s seed, once revealed, hashes to the previous round’s seed, back to the anchor. With complete, numbered public round records, a skipped or swapped seed is detectable.
A future Bitcoin block. The client seed is the hash of a specified Bitcoin block that hasn’t been mined yet, a value no one can know until the block exists. The chain and the choice of block must both be published before that block is mined. That fixes the order of seeds before a single result can be calculated.
Slide VIP as Winna describes it, had neither safeguard.
WHY IT MATTERS
The key question in this dispute is simple: were seeds chosen with their results already known? With the public Slide design, properly implemented, anyone could have checked that against records made before play. With Slide VIP, it rests on Winna’s word.
That cuts both ways: even if Winna’s account is accurate, the published records don’t independently show it.
WHERE THIS LEAVES THE DISPUTE
The dispute remains unresolved on the evidence provided. We cannot establish that the player’s results were manipulated, nor that they weren’t. Winna’s data shows which seed each round used, but a record published afterwards can’t, on its own, show how those seeds were chosen.
The lesson for the industry is that implementation matters. Fairness protections and the records needed to verify them, should be designed and tested before launch. A sound implementation gives players and operators alike evidence anyone can check, so disputes are settled by verification rather than competing accounts.
10 weeks ago we were accused of stealing $7m from a player through a rigged game. That accusation is false. The game wasn't rigged, nothing was taken, and an independent body has since confirmed it.
A lot of people have asked why we said nothing for ten weeks. Fair question. The honest answer is that our lawyers told us not to respond publicly while this was in formal proceedings, and we listened.
In hindsight, staying silent was a mistake. Silence looked like we had something to hide, which we didn’t.
There was a reason for the advice. The thread you all saw was written in the first person, as the player. But it wasn't posted by the player. It was posted by a former affiliate partner of ours, who has unresolved legal matters with Winna and is the subject of separate legal proceedings. He has since disclosed that to the regulator himself and also publicly.
That's a serious conflict of interest, and it made a public back-and-forth impossible at the time.
What changed: the complaint went to an independent dispute-resolution body. Based on the full data presented to them, they ruled in Winna's favour. The separate legal proceedings are being filed. Both are where they belong, so now we can talk.
Our CTO Ollie has answered the technical claims in detail, with a GitHub repo holding the full data and evidence. Anyone can check it themselves. Nobody has to trust either side.
I still want to address a few of the accusations made over the last weeks.
1. “Produce a valid pre-bet commitment and your server-generation logs.”
They asked for this several times. It's now public, for every round. They could have had it months ago: in the private exchange they asked for three rounds and received three. They never asked for the rest. Maybe that was a communication error. Either way, they have it now.
2. The whole implementation was visible before a single bet was placed.
Every part of the provable-fairness setup described above was shown in the fairness panel before any gameplay. The affiliate has said the player is his best friend. If he didn't like that implementation, why not tell his best friend not to play? And why was the complaint raised more than two months after the session?
I can tell you why.
- He was the player's affiliate and received affiliate commission on his play.
- He only started making these claims after we ended his affiliate relationship and asked him to resolve other, unrelated disputes between him and Winna, the matters now going to court. None of them have anything to do with provable fairness.
- And we have it in writing that he is doing this because the player promised him money if he gets something back.
Based on the above, I think everyone should question the motives behind these claims.
3. The fixed client seed.
They also raised a second point: the client seed was a fixed Bitcoin block hash and couldn’t be rotated. As above, that was visible before any gameplay, and nobody asked for a rotation or complained about it before playing.
Besides that, the player still controlled one input: when to bet. Ollie’s thread replays the player’s main session against the real results of the game, starting at different times. Had he started that same session 5 minutes later, he would have won 4 of 13 rounds and been up $3.5m. One hour later: 6 of 13 rounds, up $4m. 5 hours earlier: all 13 rounds lost, worse than what actually happened. Every seed in that table was already committed before he played. Nothing was aimed at him.
4. Even if you take the fixed client seed as an argument (we don’t), it can’t be a reason to claim losses back.
If it were, I could point at several top-20 competitors running the exact same setup right now: BetFury, Toshibet and others. Thrill had the same setup in its first two months, and the player played a similar VIP Slide there. Does that mean every Thrill player from those two months can ask for their money back?
5. “The odds of that run were 1 in 5,000.”
Not correct. The thread above walks through it. The odds were about 1 in 100. Every gambler sees runs like that. Pocket aces in poker: 1 in 221. The dealer hitting blackjack twice in a row: about 1 in 440. Red seven times in a row on a roulette wheel: about 1 in 150.
6. Betting limits
We took his high-stakes action knowing he plays an extreme style that has historically given a lot of profit back. On top of that we had paid him $1m for exclusivity, so we weren’t worried about him losing it elsewhere; we knew it would come back to us eventually.
The extra cashback came from a separate issue he had a few days earlier, which they know about. We could afford it because on our own Originals we no longer had to pay bankroll provider fees.
They also point to the limits: right after the switch to the public Slide, the limits were lower than before. True. What’s missing is that we set limits player by player, based on VIP deal, history and exposure. The claim that we would never take $100k+ bets is simply wrong. Since launch we have taken casino and sports action well above our public limits many times. Since that Slide session on 16 May we have taken 837 single bets above $100k. 101 of them were above $500k, well above his average Slide bet. All of them visible in our public bet feed, some of them here on X.
Looking forward
As I said above, not responding and letting false claims circulate in the community was a mistake. But we are confident that the evidence that has been published gives anyone looking at this without bias a clear view: the game was NOT rigged.
And we are proud that despite those false claims, our active player base has grown to record levels. They know they can trust us: instant withdrawals, fair games and strong bonusing.
This case, and a few others across the community, has shown us that provable fairness is still not widely understood. So over the past weeks we have been working on the next version of our provably fair system, which launches this year. The goal: set a new standard for the industry and make provable fairness easier for everyone to understand.
Hackers, net worth gamblers, jihadists are all of the same breed
Big balls
If you’re willing to go to prison for a long time or willing to go all on or for a cause or taking revenge for your family member being k*lled you’re the definition of “ALL IN”
All these pussies that sit behind their computer and place x% of your paycheck monthly to gamble that’s just retarded you have tiny balls and that’s why you will always lose so stop gambling
Peopre seem to think when I say I’m high as a kike I’m taking weed or psychedelics or something, those drugs are for actual retards
What I take (allegedly) is something called an etomidate vape known as kpods which is a Chinese invention
While all drugs are bad, kpods and nitrous oxide you can recover from if you’re careful and take breaks, you will do and say a lot of dumb shit while on those two, especially when it’s mixed with alcohol. But that combo (kpod coke alcohol) also sometimes helps you win on roulette, but if you overdo kpod while gambling you’re gonna be a zombie with no memory of the night and wake up with -$1m or +$10m
Basically avoid gambling if you don’t have kpod and don’t play roulette, the higher your IQ the worse you’ll be at gambling, so take drugs that make you slightly retarded temporarily
I used to think maybe 1% of gamblers win big and retire ya know in some $5000 to $5m shit
After enough hours spinning online cryptocurrency slots I can confidently 100000% say that scenario does not exist
Humanly impossible. Mathematically possible maybe, but genuinely not possible for a person to acheave that
Anyways. Most u guys knew that already. But for anyone as dumb as I used to be
Ur retarded and will never get rich in the casino. Go start a business
And before anyone asks me why I gamble then
Cuz I think it’s awesome and one of the only thing that keeps my boring sober life fun.
