Mobile Game Development

Casual and puzzle mobile game development

We make casual and puzzle games in React Native and Expo. Our own titles include a sliding-block puzzle where every one of its 100 levels is checked by a solver to have exactly one winning move, a story-driven escape game with five chapters, and a fast pattern game with six types of generated puzzle. They run offline, have accessibility options, and ship through automated release pipelines.

Is this right for you?

Problems this service solves

Mobile Game Development usually suits teams in one of these situations.

  • Brands that want a small branded game or a playful feature inside an app
  • Studios and founders with a casual or puzzle game concept
  • Educational products that need game mechanics

When we are not the right fit

We focus on 2D casual and puzzle games. For 3D or real-time multiplayer games, a specialist game-engine studio is a better choice.

How we test it

Game rules, generators and solvers have their own test suites, and level files are validated automatically so a broken level cannot ship.

What you get

Deliverables

What a typical engagement includes. We agree the exact scope with you before work starts.

  • Game design

    Core loop, levels, difficulty curve, hints and rewards, written down before build.

  • Game engine logic

    Pure, tested game rules kept separate from the screens, so levels and rules are easy to change.

  • Level tooling

    Generators, validators and solvers that check every level is fair.

  • Art, sound and feel

    SVG art drawn in code, synthesised sound effects, haptics and smooth animation.

  • Store assets

    Screenshots and feature graphics generated from real game states.

Our approach

How the work runs

The same five steps on every project, with working software to review every week.

Scope your project

  1. Share your idea

    Tell us what you want to build, who it is for and what has to be true for it to succeed.

    You get: A short written summary of the problem and a suggested first release.

  2. Plan and design

    We agree the scope, the screens and the technical approach before writing production code.

    You get: An agreed scope, designs for the key flows and a milestone plan.

  3. Build and demo weekly

    We build in small steps and give you a working version to try every week.

    You get: A tested, working product that grows each week.

  4. Launch

    We prepare the release, from store listings and privacy pages to hosting and monitoring.

    You get: Your product, live for real users.

  5. Grow

    After launch we fix, improve and extend the product based on what users actually do.

    You get: A product that keeps improving, or a smooth handover.

FAQs

Mobile Game Development: common questions

Do your games have ads or in-app purchases?

Our own games have neither, by choice. For a client game we can add either, and we will talk through how they affect the player experience and the store's data-safety rules.

Can you build a game for iOS as well as Android?

Yes. Our games are built with React Native and Expo, which target both platforms. Our own titles have launched on Android first.
