Who we are

Leono Games is an early-stage independent game studio based in Vietnam. We create approachable, engaging games for web browsers and mobile devices, with a focus on casual gameplay, intuitive design, and polished player experiences.

Our first product is an HTML5 game platform at leonogames.com, where games open in seconds on phones and computers with nothing to install. We start with games we build ourselves and games from creators we partner with; later, we'll add AI tools so creators can make games on their own. Alongside it, we're developing casual games for Android and iOS.

Our HTML5 platform

Our HTML5 platform, in two phases

We're building the platform step by step: first our own games and games from partner creators, then AI tools that let creators make games themselves.

Phase 1 · Now

Our own games + partner creators

We build our own HTML5 games with AI coding agents and our game standard, and connect with other creators to bring their games to the platform through our SDK.

Where we are today

  • Our game standard, SDK and starter template are done
  • Every demo game on the platform was built by AI coding agents (Claude Code) from a short brief
  • Each game passes automated tests, including an autopilot playthrough
  • Our developer docs are public, so creators can integrate their games
  • Next: finish technical testing, publish our own games and onboard the first partner creators
Phase 2 · Later

AI game creation for creators

Creators describe a game and our AI builds it to the platform's standard, ready to refine and publish.

How it will work

  1. Describe your idea

    Genre, rules, look and feel, in plain words.

  2. AI builds it to our standard

    Code that follows our game standard and SDK, checked by automated tests before it can go live.

  3. Refine and publish

    Playtest, tweak, and publish on Leono Games, playable instantly on any device.

What we're building

Everything below is a work in progress; names, visuals, and release plans may change as development continues.

How we make games

A great game doesn't need a huge download. It just needs a few seconds and the screen already in your hand.

  • Instant play

    Games should load fast and run well on any screen, with nothing to install.

  • Small, but polished

    We'd rather ship a small game that feels great than a big one that feels unfinished.

  • Prototype fast, iterate often

    We prototype quickly, playtest, and keep what works. A shared production workflow lets a small team build and refine several games at once.

Under the hood

The web platform is our own, built from the ground up for instant, fair play on any device.

  • Sandboxed by design

    Each game runs in a sandboxed iframe on its own origin and loads only when you press Play.

  • Our own game SDK

    One small script with zero dependencies gives games leaderboards, saved data, ads and sharing.

  • Fair leaderboards

    Every score is checked on the server against its play session before it reaches the leaderboard.

  • Fast everywhere

    Game files are delivered through Cloudflare's global network, and every page is built mobile-first.

AI in our workflow

We use AI-assisted development to speed up ideation, coding, content prototyping, and quality review. AI-generated work goes through human review and testing before it reaches our games, and creative decisions and quality control stay in human hands.

Every change is reviewed and has to pass our automated test suite before release.

Next, we're evaluating where the Claude API could help in our internal tools and future game features.

AI tools for creators to make games are planned for phase 2 of our platform; we'll explain exactly how they work when they launch. Today's games don't include player-facing AI features.
