Build, test, and publish HTML5 games on newgame.win

Getting started

Create a developer profile, create a publisher, register a game, submit a build, and move through testing tracks.

Examples

Reference games demonstrate SDK readiness, scoring, saves, and sandbox hosting.

NG SDK

A lightweight browser SDK for readiness, progress, scores, saves, and wallet operations inside the platform iframe.

Unified API

Every developer action uses /v1/api.json with a stable action name and a JSON data object.

MCP integration

Use publisher-scoped MCP tokens so agents and developer tools can manage games without sharing account passwords.

Publishing workflow

A release moves from build metadata, to review, to a release draft, to track review, and finally to activation.

Release tracks

Use internal, closed beta, open beta, and production tracks to control visibility and risk.

Localization

English is the source language. Add translations for store text and localized assets before broader rollout.

Review policy

newgame.win reviews metadata, builds, releases, and capacity changes before they affect players.

Changelog

Developer-facing platform changes that affect SDK, API, MCP, release workflow, and review policy.
