Casino Game Provider FAQ for Operators and Aggregators

Giro Games is an independent slot game studio. We design, build and license original online slot games — our own math models, art and characters in every title — for online casinos and iGaming platforms.

Midas Golden Era and Sugar Space are live on Stake.com, where both hold the maximum three-star Engine rating and sit in the platform’s recommended slots. Sugar Space joined the catalogue in August 2026. Our full catalogue, including the titles still in production, is listed on the slot games catalogue, and each game page carries its own specification.

Yes. We offer shared titles for wider networks and brand-exclusive slot games built for a single operator. Write to info@girogames.com with a few words about your platform.

Our games ship with RTP profiles from 96.00% to 97.00%, proven across millions of simulated spins before release. Exact RTP, volatility and max win are published on each game page.

A full cycle — concept and GDD, math and simulation, art and animation, development and certification — typically takes several months per title. Timelines depend on scope and target markets.

Yes — brand-exclusive originals are part of our offer: a custom theme, characters and math profile developed for your casino only. Contact us to discuss scope and timelines.

Integration runs through the platform the game is published on, not through a separate build for each operator. A title that is already live on a platform is enabled for your brand from the operator side; a title you commission from us is delivered as a finished HTML5 game with its math, assets and remote game server hooks already wired for that platform. Nothing about the game changes per operator except what you switch on: currencies, bet ranges, jurisdictional limits and the lobby thumbnail set. Write to info@girogames.com with the platform you run and we will tell you exactly what the integration involves.

Yes. Aggregators are how a small original studio reaches operators at scale, and our catalogue is built to be carried that way: consistent technical packaging, one math model per title, no per-operator forks. We are interested in both catalogue-wide arrangements and single-title pickups, and we are equally open to being the studio behind someone else’s content pipeline. The studio services page sets out the formats we work in.

Four things, and it is worth separating them. The game client — HTML5, running in a mobile browser with no download. The math model — reel strips, pay table, feature triggers, RTP and volatility, proven across millions of simulated spins. The art and animation package — symbols, backgrounds, character rigs, transitions and lobby art in every thumbnail size a platform asks for. And the sound design — the reel loop, the anticipation build, the win tiers. A provider that supplies only the client and buys in the rest is an assembler rather than a studio; everything in our titles is made in-house.

Yes, and that is a large part of what the studio does. A commission can be a full title from concept to release, or a scoped part of one: the concept and game design document, the math and simulation, the art and animation, the sound, or the development itself. We also take on dedicated-team arrangements where your producer runs the schedule and our people do the production. Projects are quoted individually — there is no fixed price list, because a five-symbol classic and a cascading multi-feature title are not the same job. Start with slot game development services, then discuss your project.

The game design document is what production is built from: reel layout, symbol set, pay table, feature list and trigger logic, the math targets, the art direction, the sound brief and the platform the title ships on. Everything downstream — simulation, art production, development, platform review — reads from it. Skipping it is the most common reason a slot project runs late, because art gets drawn for mechanics the math has not confirmed yet. We publish a working template in the twelve-page slot GDD walkthrough.

The math model starts from the targets in the GDD — RTP band, hit frequency, volatility, maximum win — and is written as reel strips plus a pay table plus feature trigger rules. It is then simulated: millions of spins per configuration, checking that the realised RTP converges on target, that the win distribution has the shape the design asked for, and that the maximum win is reachable but rare. The output is the PAR sheet, the summary every platform reviewer and every operator’s game team reads. What a PAR sheet contains, line by line goes through a real one.

Released titles ship with RTP profiles between 96.00% and 97.00%. Volatility is a design decision rather than a house style: we build low-variance titles where the session has to last, and high-variance titles where the maximum win carries the game. Exact RTP, volatility and maximum win for each title are published on its own game page and match the figures shown by the platform the game runs on — if the two ever differ, the platform’s page is the correct one. How studios tune slot volatility explains what the choice changes for players.

Yes — a title built for one operator and carried by no one else, either as an original concept or as an adaptation of a Giro Games project that has not been released yet. Exclusivity is agreed per project, together with the term and the territory. We also sell outright: a finished or in-production title acquired by a single operator before release. Both routes start the same way, with a conversation about your players rather than about our catalogue — discuss an exclusive slot project.

A full original title runs three to five months. Concept and GDD take two to four weeks. Math and simulation run three to six weeks and overlap with art direction. Art and animation are the longest single stretch, six to ten weeks depending on how many characters are rigged. Development runs in parallel from the moment the math is stable, then platform review and fixes take two to four weeks. A scoped commission — art only, math only, sound only — is measured in weeks rather than months, and an adaptation of an existing concept is faster than either. The full production cycle, from GDD to release walks through each stage.

Stake Engine is the platform our released titles are built on. It supplies the remote game server, the math validation and the review process a title has to pass before it goes live, and it publishes the resulting game to the operators on its network. For an operator that means a title arrives already reviewed against a published standard rather than as a raw build. Stake Engine explained for studios covers the submission and review flow in detail.

On a commission the deliverables and the rights are set out per project before production starts — a client paying for an exclusive title normally takes the title, while we keep our engine-side tooling and reusable libraries. On our own catalogue titles the studio owns everything, which is what lets us re-skin, adapt or sell a project outright. Nothing we deliver contains third-party art or audio that cannot be passed on with it.

Send a short note to info@girogames.com with three things: what you need (a full title, a part of one, or a team), roughly when you need it, and the platform or network it has to run on. That is enough for us to come back with a realistic scope and schedule. If you would rather see how we work first, the studio page explains the production pipeline, the slot games catalogue shows the titles it produced, and what operators should look for in a slot provider lists the questions worth asking any studio, including us.
