Moderators and streamers can run both polls and raffles in the chat. Only one runs at a time: a poll will not start while a raffle is going, and a raffle will not start during a poll.
Type /poll to start a poll. A poll needs a title and at least two options.
Duration is optional and caps at 30 minutes; with no duration the poll runs
until you close it.
Viewers vote in the chat panel and see the running count. Each person gets one vote and cannot change it.
Add a Browser Source in OBS pointing at:
https://piczel.tv/chat/<username>/poll
300 by 300 pixels suits it. The overlay is blank when no poll is running, so you can leave the source in your scene.
Type /raffle and pick a type.
Manual raffle lets you list who takes part and draws as soon as you confirm.
Opt-in raffle puts a Join button in chat. Options:
Only signed-in accounts can enter; anonymous viewers are asked to sign up. You can remove someone from the entrant list, cancel the raffle before it draws, or trigger the draw early. Starting another opt-in raffle while one is running asks whether to replace it.
Viewers who would rather not see the animation can turn off raffle confetti.
