We make games — fast, and for less

solvX makes browser games — a simple one we can turn around in hours, or a custom game for your business, from marketing games to a one-off for an event. We work browser-native with Three.js, WebGL, Rapier physics and Colyseus, and move to Unity or Unreal when a project needs it. AI-assisted development keeps it fast and affordable.

Coming soonBirthday & event games — a custom little game made for a birthday, party or celebration. Register your interest and we'll tell you the moment it launches.

What we make

Games and the parts games are made of

Three.js WebGL Rapier (physics) Colyseus (multiplayer) TypeScript Unity Unreal Engine AI-assisted development

Who it's for

Made for people with an idea worth playing

Founders & start-ups

A playable prototype that proves the concept — to you, to players, to investors.

Marketing teams & brands

A campaign game people actually engage with, running in the browser with no install.

Agencies & studios

Overflow game builds and browser-native prototypes you can put your name on.

Independent game makers

An engineering partner to build the systems while you focus on design and content.

How projects work

Brief → prototype → review → production → delivery

1

Brief

The idea, the core mechanic, and where it needs to run.

2

Prototype

A playable version of the core loop so you can feel it, not just read it.

3

Review

You play it and steer it before we scale up the build.

4

Production

Systems, content and polish — multiplayer and physics where needed.

5

Delivery

A game that runs where you need it — a link, a build, or a store package.

Typical scope

How big is your game?

A rough guide to where your game sits and what it typically costs. These are starting points — the final figure depends on scope and complexity, so tell us the specifics and we'll confirm.

Small

from £20

A single-mechanic browser game — enough to prove the idea is fun, or a simple game for a campaign or event.

Medium

from £50

A polished single-player game, or a multiplayer prototype with real-time rooms and movement.

Substantial

£100+

A full multiplayer game with matchmaking, content and progression — or a cross-platform Unity/Unreal build.

Evidence

Real games we've built and put in the browser

Bang Bop — a multiplayer car-combat prototype

An internal MVP — a real-time, multiplayer car-combat game that runs in the browser, with nothing to install.

ObjectiveFind out whether the core loop is genuinely fun, and whether real-time multiplayer holds up, before committing to a full game.
What we builtAn 8-player arena: drive and drift, fire plasma bolts, lose lives, get eliminated and restart rounds, with a live scoreboard. Vehicles are procedural JSON blueprints; gamepads supported.
TechnologyTypeScript, Vite, Three.js and WebGL for rendering; Rapier for 3D physics; Colyseus for authoritative multiplayer; Zod for validated data.
ResultA working, playable slice that answered both questions — the kind of prototype we build to de-risk a game before full production.

SPLITFIRE — a browser first-person shooter

A multiplayer first-person shooter that runs entirely in the browser — no download, no build step, just a link. Proof that real-time action multiplayer works browser-native.

ObjectiveShip a real-time multiplayer FPS that anyone can play instantly from a URL.
What we builtA browser FPS with real-time movement and shooting, and server-synchronised multiplayer rooms.
TechnologyThree.js and WebGL for 3D in the browser; Colyseus for multiplayer state; plain JavaScript, no build step.
ResultA playable browser FPS — see it on the SPLITFIRE page.

Common questions

What people ask before commissioning a game

How much does a browser game cost?
As a rough guide: a small job — a single-mechanic browser game or a simple game for an event — starts around £20; a medium project — a polished single-player game or a multiplayer prototype — around £50; and a substantial one — a full multiplayer game with matchmaking and content, or a cross-platform Unity/Unreal build — from £100. The final figure depends on scope and whether it needs multiplayer, so tell us the idea and we'll confirm.
How long does a game take?
A small game — one simple mechanic in the browser — can often be done within a day with AI-assisted development. A multiplayer prototype takes longer because of networking and server state, but you still see something playable early rather than at the end. Whatever the size, we work to minimise the time it takes.
Browser game vs Unity vs Unreal — which should I use?
A browser game (Three.js / WebGL) runs instantly from a link with nothing to install — ideal for marketing games, prototypes and anything you want people to try in one click. Unity suits larger cross-platform and mobile games; Unreal suits high-end 3D. We build browser-native by default and move to Unity or Unreal when the project genuinely needs it.
Can a promotional game run directly in a browser?
Yes — that's the point of building browser-native. A branded game opens from a URL with no download or app store, so people play it in one click and share the link. Our own prototypes, a multiplayer car-combat game and a browser FPS, both run this way.
Can AI reduce the cost of game development?
For the parts that are code and content, meaningfully. AI-assisted development speeds up building systems, tooling and iterations, so you reach a playable version faster and spend budget on making it good rather than getting it working. Design judgement and playtesting stay human.
