TWITCHMONSTERS

Twitch Monsters is an interactive Twitch chat game for streamers and their communities. Viewers summon AI-generated pixel monsters from chat prompts, and up to eight heroes fight them in a multiplayer browser arena. Each run is a 100-wave survival challenge.

Viewers vote on the next monsters, summon enemies with !summon, send loot with !gift and become companions with !pet. Twitch subs, bits and channel points unlock custom words. The streamer fights while chat changes what happens in the arena.

Yes. YouTube creators can play the browser game and record gameplay, multiplayer sessions or the 100-wave challenge for their videos. The live chat integration currently connects to Twitch; YouTube live chat commands are not supported.

Play in a desktop browser and capture the game in OBS. Once invited to host, connect your Twitch channel and add your arena's OBS overlay as a browser source. Show the room's QR code so viewers can vote and summon from their phones, and invite friends through the players link.

No. Chat commands work in Twitch chat, and the stream's QR code opens a phone page in the browser. Heroes play in the browser on a computer.

Votes, free picks and pets are free. Your own words take a credit: a sub, a cheer of 100 bits or more, or a channel points reward the streamer sets up.

Custom words go through a word filter (English and French, leetspeak included) and AI moderation. Turn on approval mode and nothing chat writes spawns until you accept it. You can also ban words from your control panel.

It paints the sprite and writes the monster's name and flavour. For words the game doesn't know, it may also pick the element and fighting style, from the game's own list. Every number comes from fixed tables, and a procedural sprite shows up instantly, so nobody waits for the AI and nobody can prompt an overpowered monster.

Every arena runs live on our server, so hosting is invite-only while we open arenas a few at a time, with no dates yet. Invites go out from the list by private message on Twitch, and each link works once, for one Twitch account.

Only who you are: your Twitch id and login. The waiting list asks for no permission on your channel. We keep your Twitch id, login and the date, and no IP address.

Not by itself: nominations show us which streamers chat wants most. What tells them is you, pasting the message in their chat.

Any recent desktop browser for the 3D arena: WebGPU where it can, WebGL 2 everywhere else. On a phone, viewers play along from the phone page.
