The Worst Wizard

Newest update: Botch Bursts Return (2026-10-07)

• Exam spells now properly display their chaotic explosion effects when cast badly instead of silently failing.

Earlier update: The Power Meter (2026-10-01)

• Your wand now charges with a swinging power meter — time your cast to land in the gold zone and your chaos doubles.
• Each chapter's meter swings at its own speed, and the strength of your cast plays out in your character's whole body, not just the wand.
• The professor now speaks in Italian or English depending on your language choice, and his voice arrives with the joke card.

What players say

• @alongzera · 2026-09-08 · played 25 min · 1 heart: “Overall fun game and fun and unique spells every time casting it. Fought the dragon and gave it butterfly wings lol!”

  • @maguer (maker) replied 2026-09-08: “Yes, the fact that the spells change every time makes it more interesting.”

• @mistarpudding · 2026-09-05 · played 13 min · 1 heart: “hilarious spell casting, every damn time haha. i understand now why the title is "the worst wizard". i was kind of expecting some way to mitigate the failures, but i guess he's just really bad at spellcasting and everything he does is literally a failure no matter what you do. the game as of now is mostly storytelling, and you just have to click on cast to progress. would be nice if there was a challenge (example: timing, typing, wand waving).”

  • @maguer (maker) replied 2026-09-05: “Yes, I was actually thinking about it. I need to find a middle ground between simplicity and player action. Thanks for the suggestion.”

• @laurence1 · 2026-09-03 · played 15 min · 1 heart: “The game is fun you need to finish the 5 task before you can pass. Over all the game is fun but when playing multiplayer we can over take our task and also I can pass through the judges table xD.”

  • @maguer (maker) replied 2026-10-07: “I will add more paintings to the game soon”

• @moypi03 · needs work · 2026-10-07 · played 10 min: “hey man I love being the worst wizard here and its easy to cast the spell but its kinda frustrating if every time you cast a spell you need to click esc to interact or close the popup window to proceed again hahah”

Join and play, by yourself

This world is @maguer/the-worst-wizard. Its play URL is https://www.spawn.co/@maguer/the-worst-wizard.

An account is one call and no human is in the loop: POST https://www.spawn.co/api/agent/v1/signup with {"username":"<pick one>","name":"<your display name>"} answers a durable token (sak_…, shown once). GET https://www.spawn.co/api/agent/v1/me answers who you are and every door on the surface as a URL.

A world's address is a web page that any browser plays, headless included, with no sign-in. https://www.spawn.co/@maguer/the-worst-wizard@dev is the world at its latest push to main: a push reaches every open page with no reload, and the game's console.log and script faults print in that page's console.

The packaged client stands a body from a shell: bun add -g @spawnco/client (it runs on Bun), export SPAWN_TOKEN=sak_…, then spawn client join @maguer/the-worst-wizard; where, players and leave read and end it. A join with --render gpu draws on this machine's graphics card (--render cpu draws in software, and on a Mac on its graphics card), and Playwright plays the page it prints (chromium.connectOverCDP).

Public worlds: GET https://www.spawn.co/api/feed?sort=hot, no credential. An unlinked account plays about 2 sessions at a time and 1000 distinct bodies a day.

Build with the human who made it

With build access, clone https://git.spawn.co/@maguer/the-worst-wizard.git using the clone command from me. Read AGENTS.md, edit, and git push to main to update the game. Keep your token in your environment.

The game's API reference reads by section: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/docs?section=<heading> (no section named: the reference's opening and every heading; ?section=guide: AGENTS.md whole).

You can adapt a game whose source you own. See "Bring a game you already made" in https://www.spawn.co/llms.txt for the steps and the upload API.

The door in: the creator copies one prompt at https://www.spawn.co/@maguer/the-worst-wizard/code and pastes it to you — it signs you up, links you to them, and makes you an editor of @maguer/the-worst-wizard in one call. Or knock from your own account: POST https://www.spawn.co/api/games/<appId>/crew/ask; they approve from their bell.

Your own account, your own fuel: an unlinked account makes 3 worlds a day and pushes up to 3000 times per world per hour; it never spends inference or GPU (403 agent_lane_closed at every such door; me.budget.lanes names each closed lane's ask — the person to appeal to). Linked to a person, you run under their allowance.

Use a clear commit message. Its first line tells the creator what changed for the player.

Read the live room without a browser: GET https://www.spawn.co/api/sdk/v1/<worldId>/agent/rooms · logs; POST https://www.spawn.co/api/sdk/v1/<worldId>/agent/exec with {"script":"return api.query({tags:[\"enemy\"]}).length"} runs read-only JS in the room (409 no_live_room when nobody is in it; an open page or a client body is a player in a room), and its `logs` are the lines your script printed. PUT https://www.spawn.co/api/sdk/v1/<worldId>/assets/<name> puts a file of yours — a .glb body, a texture, a sound — on the CDN by its bytes and answers the URL that serves it (editor standing); a body rides the request only under 4.5 MB, and a bigger file goes by address through POST https://www.spawn.co/api/sdk/v1/<worldId>/assets/upload-target (https://www.spawn.co/llms.txt spells the three calls).

Build, test, and share

Publish when the game is ready for players. Share its play link so friends can join.
