Casino game studio for operators
One counts.
One dares.
Games with a face, not anonymous slots. Recognisable heroes, economics tuned to your market, a round you can verify byte for byte — and one seamless contract for the whole catalogue.
The case files
Studio cases. Play any of them here.
Play-money demos, no sign-up — with the very same maths as the real-money game.
Why Kvinter Finter
Character for players. Control for operators.
We don't compete on catalogue size. Our edge is games players recognise — and economics you tune yourself.
Economics for your market
Difficulty levels, bet limits, currencies, skin and campaigns are set per operator by configuration — no separate game build.
The money stays with you
Seamless only: we call your wallet API and guarantee idempotency, rollbacks and period reconciliation.
Every round is verifiable
Rounds replay byte for byte on a frozen ChaCha20 generator, and players can verify any closed round on a public page.
Heroes players come back to
Kvinter and Finter move from game to game. Every new release continues a familiar story instead of becoming yet another nameless slot.
Promotions inside the game
Free rounds from your promo budget, missions, tournaments, a jackpot and Prize Drops — all over the same integration.
One integration, the whole catalogue
Our protocol, or a mode compatible with Plain. New games appear in your lobby without another integration.
Our red line: no personal odds
Campaigns only ever target player segments — our data model has no path from a setting to an individual player. It's not a promise, it's the architecture.

Integration
One pipe for the whole kontora
Like the pneumatic post in an old office: one main line from your wallet, and the capsules find their own way to every game.
- Exchange keysEvery request is signed with RSA-SHA256, in both directions.
- Connect the walletUse our protocol — or the compatibility mode with the widespread Plain protocol, if your wallet bridge already works that way.
- You get the whole catalogueNew games arrive without a new integration — with covers, descriptions and demos.
For operators
What an operator gets
Everything to connect, test and run the catalogue — in one package.
A contract, not a brochure
Two OpenAPI files — one for what you call, one for the wallet you implement — plus a specification of edge cases and a changelog.
A separate sandbox
Its own environment with its own keys and no shared data with production. Test the signature, the wallet and the edge cases before real money.
A catalogue API
The game list with RTP, volatility, platforms, languages and currencies, and a play-money demo for every game.
An operator cabinet
Turnover and GGR, a call log, promotions, missions, tournaments and the jackpot — in one place.
Disputes you can settle
Every closed round has a public verification page, and any dispute can be traced step by step.
Money that doesn't get lost
Idempotent calls, win and rollback retried for at least 24 hours, and a transaction list for reconciliation up to 13 months back.
Meet the characters
Two co-owners of the kontora
Kvinter and Finter are two co-owners with opposite views on risk. Every game we make is their argument.

File no. 1
Kvinter
Tall, dry and always on time. He won't set foot on a roof until he has counted the steps — and he's the first to know every game's volatility.
- In charge of
- maths, limits, reconciliation
- Line
- “Kvinter's cases” — measured levels
- Lucky charm
- a pocket watch





“First we count. Then we play.”

File no. 2
Finter
A head shorter and twice as fast. He dashes in front of trams, soars over the city on a brass jetpack and never lets go of his battered briefcase.
- In charge of
- mechanics, pace, multipliers
- Line
- “Finter's cases” — daring levels
- Lucky charm
- a brass coin





“We'll do the counting on the other side.”
Questions for the kontora
Operator FAQ
Didn't find your answer? Ring the bell below — we reply within one business day.
How do we connect the games?
We exchange keys, you implement one wallet protocol (seamless) — and you get the whole catalogue. New games arrive without another integration.
What can we configure?
Difficulty levels, bet limits, currencies, skin and promo campaigns — by configuration, without a separate game build. A skin never changes the maths.
Is there a demo for players?
Yes. Every game has a play-money demo — no wallet calls and no winnings. The maths is exactly the same as in the real-money game.
How can a player verify a round?
Every round replays byte for byte. Any closed round can be checked on a public page, and operators can trace any dispute step by step.
Which currencies do the games support?
Euro, Ukrainian hryvnia and the GOLD brand coin; some games also take mBTC. The catalogue API lists the currencies and languages of every game.

The bell is on the desk. Kvinter answers about integration and numbers, Finter about exclusives and campaigns.
