Game provider
Games your compliance officer can sign, and your finance team can reconcile.
WINO builds slot games and runs the service that puts them inside your casino. Your players never leave your site. Their money never leaves your wallet. We hold no balance, run no cashier and ask for no card details, which is one fewer thing for your regulator to look at.
The catalogue
One foundation, more than one face
Our titles are a family rather than a list. They share one fixed mathematical model, the same proof that a round was not decided in our favour, and one integration: adding the next one to your lobby is a setting, not a project.
What changes between them is the thing a player came for. The artwork, the vocabulary, the feature each one leads with.
Emerald Tree
The same mathematics in emerald and black, with its own fruit and its own feature bank. Buy in with one, two or three wilds on the board, or let the mystery package choose for you.

Open the operator's casinoIt is a partner's site rather than a showroom of ours: a real integration, a real wallet, real rounds settling against it. Play there and the game you are playing is the game your players would get.
Fairness
Nothing is decided after the money moves.
The order matters more than the promise. The outcome of a round exists before a single unit of currency is touched, and it was settled by a number we published a fingerprint of before the player chose theirs.
That is the difference between a game you have to trust and a game anyone can check. It is also the paragraph your compliance officer will read twice, so we made it something they can watch instead.
We commit
A secret number is drawn and sealed. Its fingerprint is published while it is still sealed, so it cannot be changed afterwards.
The player adds theirs
A number of the player's own choosing goes in on top. Neither side can steer the result, because neither side holds both halves of it.
The board is drawn
The outcome is taken from both numbers together, out of a bank of boards that was built, weighted and evaluated long before anyone sat down.
Only then, the money
Your wallet is asked to move the stake and to credit whatever the round paid. By that point there is nothing left to decide.
Integration
What it costs you to carry us
You already have the hard part: a ledger that knows what every player is worth. We do not want a copy of it. We want permission to ask it two questions during a round, and an answer we can repeat safely if the network eats one.
That is the whole of it. The rest — the game client, the session, the reporting, the fairness record — is ours.
We enable your brand
You tell us which titles, which currencies and which stake levels. Your configuration is versioned on our side, so a change made while somebody is playing cannot reach the round in front of them.
OursYou connect your wallet
One connection, signed both ways, that can take a stake and credit a payout and will answer the same way twice if it is asked twice. Your engineers write it against a sandbox where nothing is real and nothing costs anything.
YoursWe run conformance, then switch you on
A suite works through the awkward cases against your wallet — the repeated request, the reversal for something you never applied, the timeout in the middle of a round — and shows you each result as it goes. Going live needs two people on our side.
Both
The full technical guide lives in the partner portal, behind your account, generated from the same specification the service validates against. Ask us and it is yours the same week.
Evidence
The figures, and where they come from
- Return to player
- 96.8%
- The default model. Models at 94.0, 98.0 and 100.0 percent are available too, and play money always runs at 100.
- Boards in the bank
- 127,040
- Every board a base game can ever show, built and weighted in advance and evaluated before a player sees one.
- Signature window
- 300s
- How long a signed request stays valid. A request that arrives twice inside it is refused rather than applied twice.
None of these is a marketing figure. Each one is a value in a file the service refuses to start without.
Operations
At three in the morning
Games fail at the worst hour, so the question is not whether something will go wrong but what state it leaves behind when it does.
A round is written down before any money moves, and settlement runs with a lease on it. A process dying halfway through leaves a round you can resume rather than a hole in a ledger. Money movements and configuration changes are journals: the database declines to rewrite them, so the morning after is reading rather than reconstruction.
If your wallet is the thing that is down, we retry with backoff and nothing is lost and nothing is applied twice. Rounds still pending are visible to you and to us at the same time, on the same screen, which is what stops the call becoming an argument about whose numbers are right.
If you run a platform and you want games your compliance team can approve without a three-month argument, start a conversation.
