Retired experiments. Still playable, kept for the record.
Records
No bests in this browser yet. Play a game and finish a round to set one.
Spotlight
Every game here aims to hold someone who likes it for 10 minutes. Your play tells us which ones get there, and what to fix in the rest.
Play one of these next
- Pick a game. Any one on this page.
- Play until you'd stop. When you'd normally put it down is the number we need.
- Rate it with the ★ button in the game's toolbar. One sentence about where you got stuck or bored helps most.
For teachers
Every game here is a small working system: a few simple rules that add up to behavior nobody wrote down directly. That makes them useful for talking about systems, feedback loops and design, in science, computing or design classes.
Free, no accounts, no installs
A browser on a phone, tablet, Chromebook or PC is enough. Nothing to sign up for.
Offline copies
Open a game and choose Download a copy. You get one HTML file that runs in any browser with no network at all, so it works on a locked-down school network or a computer with no internet. Copies send nothing.
For a lab: Download all as zip next to a subject below gives every game of it plus a page that lists them. Unzip it (Extract all), copy the folder to each computer and open index.html.
Classroom mode
Share this link with your class instead of the usual one. On every device that opens it, the arcade sends no play stats, hides the leaderboard name controls (everyone keeps a made-up name like "Amber Otter") and hides the rating and feedback buttons. It stays on in that browser, in every game, until someone presses Turn off in the note at the top of the page.
Class challenge
Make a link that gives everyone the same run of one game, so the class can compare results. Each student's first run is their result; after that it's practice. There's no leaderboard and nothing to sign up for: students show you the result card at the end (the calendar button in the game) or read their score out.

Games by subject
From the games' own topic tags, so it's always current. A subject opens the gallery filtered to it; a game opens it.

Privacy
- Anonymous play stats. To tune the games, the arcade records time played, wins and losses, scores and achievements. No accounts, no cookies, no names unless a player types one. Classroom mode turns them off; so does Settings (the gear icon) for one browser, and the offline copies send nothing.
- Leaderboards are public. They show a made-up name unless a player types their own (only players who say they are 13 or older can), and anyone can see it. Ask students to keep the made-up name or use a nickname, never their real name. Classroom mode hides the name controls.
- Progress stays in the browser. Bests and achievements are saved on the device, not on a server. Settings can export, import or erase them.
Going further
- Read the code. Each game is one self-contained HTML file in games/ on GitHub. Students who know some JavaScript can find the rules that make the behavior.
- How the games are designed: the design rules and the design findings, what worked and what didn't.
- Reuse. The code is MIT licensed and the docs are CC BY 4.0 (license): copy, adapt and share them in class, with credit.
