Claude Arcade

This repo is both a plugin (plugins/claude-arcade/) and a plugin marketplace (.claude-plugin/marketplace.json). You can install it with one command — see below.

Watch your tokens come to life. While Claude Code runs, the character runs, jumps, and collects coins. While Claude thinks, the character charges up. While Claude waits for your input, a ? block appears.

Games

Claude Arcade is built to host multiple arcade games for Claude Code — each one a tiny pixel game whose visuals are driven entirely by what's happening in your live session (tokens, prompts, tools, context pressure, etc.). Right now it ships with one:

Super Mario Runner

An auto-playing side-scroller. You don't control Mario — your Claude Code session does. Token throughput becomes his running speed, thinking becomes a glow, prompts become jumps, subagents become tiny tinted sidekicks, and a filling context window literally rains and burns down the level. Each cell below is a distinct in-game state and when it triggers.

Normal gameplay Tokens are flowing — Mario walks/runs/sprints based on tok/s, HUD numbers tick up	Thinking Claude is processing (no tokens yet) — Mario glows and a … thought bubble appears	Waiting for your input Claude is waiting on your reply — ? block appears, character taps foot, tab title flashes
Token burst First big chunk of output after thinking — speed boost with a star streak	Subagent spawn Every time Claude spawns a subagent, a small tinted Mario joins the level and runs alongside the main one	Task complete Claude finishes a task or turn — fireworks celebration, coin counter pops
Context 60% — rain Context window passes 60% — sky darkens, rain starts	Context 80% — fire Context window passes 80% — red sky, fire embers drifting	Context 90% — shake Context window passes 90% — screen shakes, time to clear context

Install (recommended)

Add the marketplace, then install the plugin. From inside any Claude Code session:

/plugin marketplace add jaipatel248/claude-arcade
/plugin install claude-arcade@claude-arcade

That's it. Run the game with:

/claude-arcade:super-mario-runner

Pick a different port if 3248 is busy:

/claude-arcade:super-mario-runner 4000

Updating

/plugin marketplace update claude-arcade

Uninstalling

/plugin uninstall claude-arcade@claude-arcade
/plugin marketplace remove claude-arcade

---

Local development install

Without going through the marketplace — useful when iterating on the plugin source:

git clone https://github.com/jaipatel248/claude-arcade.git
claude --plugin-dir ./claude-arcade/plugins/claude-arcade

After editing files, run /reload-plugins inside the session to pick up changes without restarting.
