Introduction

GameKit UI is an open-source registry of minimal, themeable browser games packaged as React/TSX components. Drop one into a 404 page, an empty state, a loading screen, or a landing-page easter egg — it installs with the shadcn CLI and inherits your theme automatically.

No provider. No peer deps. No init step.

Principles

• Minimal — each game is a single drop-in file with zero npm dependencies beyond react and your existing cn helper.
• Themeable — the theme's --primary / --secondary / --accent drive the playfield, not just the chrome. Change your theme and the games recolor.
• Zero assets — no images, audio, or fonts. Every pixel is drawn with CSS or <canvas>.
• Accessible — keyboard + touch input, focus rings, aria-live announcements, and prefers-reduced-motion support in every game.

Next steps

• Installation — set up the registry and install your first game.
• Games — browse the full lineup with live previews.
