Casino Game Development Outsourcing: Slots, Art & Animation

Outsource casino game development to the studio behind Midas Golden Era and Sugar Space. Giro Games builds complete slot games, delivers scoped parts of production — art, animation, sound design, math, game logic, HTML5 code — or brings a dedicated casino game development team into yours. Every game we ship is live on Stake Engine with the maximum three-star rating.

Three ways to work with us

From a single asset to a complete game

Team size and scope shaped to your project — and one point of contact whichever format you choose.

Full production

Custom slot game development from your concept or ours: game design document, math model and simulation, art and animation, engineering, certification support and release. One team, one timeline, one deliverable — a finished game.

Scoped deliverables

Commission exactly what your project needs: slot game art and animation, character and symbol design, UI, sound design and music, game logic, mathematics or HTML5 development. Fixed scope, fixed quote, agreed hand-over.

Dedicated team

Hire slot game developers, artists, animators or a math designer from Giro Games for your roadmap — the whole studio or the specialists you are missing, working inside your process and tools.

Proof of work

What we do

Casino game development end to end — or any part of it

The same disciplines that build our own slots, available to studios, publishers and iGaming platforms.

Game concept and design

Theme, features, bonus structure and player fantasy written into a game design document you can build against — with us or with your own team.

Slot game art and animation

Characters, symbols, backgrounds, UI and effects in a consistent 2D style, animated for the reels: symbol wins, big-win sequences, bonus scenes and idle loops. Slot game art outsourcing for studios that need capacity without adding headcount.

Slot game sound design and music

Sound sets the mood of a slot before the first spin lands, so we build it as part of the game, not a layer added at the end: original music and the full sound effects set — spins, wins, anticipation and near-miss cues, big-win fanfares, bonus themes, UI. Music is layered and state-driven, building tension as the reels slow and a feature approaches. Delivered mixed, loudness-matched and game-ready — game audio services for slots that feel as good as they look.

Game logic and mathematics

Reel strips, pay tables, feature logic and volatility tuned to a target RTP; simulation across billions of spins; documentation for certification. We design the math for our own games — the same models run on Stake today.

HTML5 slot game development

Engineering of the client and the game-server logic, integration with your RGS or platform, mobile performance, QA and release support.

Stake Engine development

Stake Engine game development end to end: the maths in the Math SDK format (books, lookup tables, bet modes), the client on the Frontend SDK, submission and the pre-release review, where Midas Golden Era and Sugar Space earned the maximum three-star rating. For studios that want a Stake Engine partner and for brands that want an Only-on-Stake exclusive slot built by a team already live on the platform.

Co-production on Giro Games projects

FAQ

Questions studios and platforms ask us

How much does it cost to develop a slot game?

It depends on scope: a full original slot with custom art, animation and a certified math model is a different project from a reskin or a single feature. We quote per project after a short brief; most enquiries receive a scoped proposal within a week.

Who develops slot machines and online slots?

Studios like Giro Games: teams that combine game design, 2D art and animation, mathematics and software. Our own titles run on Stake, and the same team is available for client projects.

Can you work only on art or only on math?

Yes. Scoped deliverables are a core format — slot game art and animation, or a math model with simulation and documentation, delivered into your existing pipeline.

Do you do sound design and music for slot games?

Yes. Sound is part of every Giro Games production: original music, the full slot sound effects set — spins, wins, anticipation cues, big-win fanfares, bonus themes and UI — and adaptive, state-driven audio that builds tension as a feature approaches. It is available as a scoped deliverable for your own game or as part of full production.

Do you work with existing projects?

Yes. We join at any stage — from a concept that needs a game design document to a built game that needs a new theme, better animation or a rebalanced math profile.

Do you develop for Stake Engine?

Yes — three Giro Games titles are live there, two with the maximum three-star review rating. We build to the platform format and support the submission and review.

Who owns the rights to the finished work?

Agreed per project and written into the proposal: full transfer for commissioned work, or licensing and exclusivity terms for Giro Games projects.
