1. Create a host room
Choose a room name and classic or reverse mode. Acknowledge the public-data notice and create the room. Your host key is saved in this browser. You may download a private backup from the host-key section. Lost keys cannot be reissued.
2. Invite your viewers
Share the invite URL in Twitch chat. Viewers open it and enter a display name. Ask for one card per person, no real names or contact details. No login identity check is performed. You can also add names manually, one per line. Automatic !bingo chat entry is not included.
3. Capture the display
Open the stream display and capture that window in OBS. Do not show host controls or private keys. Filter cards by name and check readability on a small viewing screen.
4. Draw numbers
The first draw closes entry. Viewer screens refresh about every 15 seconds, so allow time for updates. Numbers never repeat. After a connection error, check the latest number and draw count before repeating an action.
5. Another round or finish
A new round keeps players but regenerates all cards. Enter normal or reverse to choose the next mode. Delete the room after use, or allow its access to expire 24 hours after creation.
Limits and support
Creation is limited to six rooms per hour per connection source; entry is limited to 15 attempts per minute per room and connection source. Shared networks may hit these limits. Free hosting quotas may interrupt service. Start with a small live rehearsal. Never send passwords or host keys to support.
