cc-arcade

cc-arcade puts a game above the Claude Code prompt for the minutes Claude spends working. Run /arcade, click a game, and play. When Claude’s turn finishes, the game pauses and its status line says so. Nothing here asks the model anything, so playing costs zero tokens.

What it does

• Nine games: Snake, Tetris, Doom, 2048, Minesweeper, Flappy, Pong, a typing test and Space Invaders. Doom is a small first-person corridor shooter with four floors, three monsters and three weapons, drawn with half blocks. The levels are the author’s own, not id Software’s.
• A pet that grows with Claude’s work. Passing tests, commits and file edits feed it, and it survives restarts.
• Best scores per game, kept across sessions. /arcade list shows them.
• /arcade auto picks a game for the moment: a quick round while Claude is on a short turn, something deeper once the turn has run over a minute, the pet after a failed test run.
• /arcade colorblind switches Doom to a palette that does not rely on red against green.

Install

Needs Claude Code 2.1.287 or later, an interactive terminal, and a terminal that reports the mouse.

claude plugin marketplace add sezaakgun/cc-arcade
claude plugin install cc-arcade@cc-arcade

Start claude and run /arcade. Click a board to give it the keyboard. Esc gives the keyboard back to the prompt.

How it works

The plugin draws in the band Claude Code gives plugins above the prompt, about half the terminal height, and redraws ten times a second (Doom twenty). Each board is a Client module with its own frame clock, keyboard and mouse, so input never goes through the model.

To feed the pet it hooks every tool call, which means it sees each Bash command and whether the call failed. It keeps counters only: no command text, file path or prompt is stored, and it makes no network calls. Scores and the pet live in Claude Code’s plugin store on your machine.

Limitations

• Draws only in interactive sessions: nothing appears in claude -p or the VS Code extension’s chat panel. The author documents the terminal only; the Desktop app’s Code tab is untested.
• One game at a time, and a board only gets the keyboard after a click.
• The games are clones of the genre. The author states they are not affiliated with Tetris Holding, Taito, Atari or id Software.
