Option Settings
Green Screen
Turn ON to make the background green, suitable for chroma key compositing.
Performance
When ON, displays confetti effects and winner cards upon selection. Turn OFF for a quieter lottery.
Text Color (Black)
When ON, changes text color to black for roulette and other modes. Useful when using bright backgrounds.
Open in a New Window (Stream Window)
Keeps the control panel in front of you while the drawing itself moves to its own window. Your viewers see the lottery, not you typing names into it.
- Click the "Stream Window" icon at the bottom right of the main screen
- The drawing and the winner animation stay in sync in real time (while both are open in the same browser)
- Reloading the main screen does not break the sync
- In OBS, pick up that window with Window Capture
Which one to use: Putting the Kime-Toku URL straight into an OBS Browser Source is covered in the OBS transparent roulette guide. Use the stream window when you run draws live from one machine; use a browser source when you set it up once and leave it.
How to Use with OBS
Add Browser Source
In OBS Studio, select "Sources" → "+" → "Browser".
Set URL
Enter https://kime-toku.com/en/ as the URL. Adjust width and height according to your stream (recommended: 1280x720).
Transparency Settings (Optional)
Leave "Custom CSS" empty and check "Enable transparency" to overlay only the lottery portion on your stream screen.
Tip: You can also capture the window opened with "Open in a New Window" using OBS's "Window Capture". Full walkthrough: OBS transparent roulette guide.
Embed the lottery on your own site
Paste an iframe into a blog post or an internal page and whoever is reading it can run the draw right there. No more "please open Kime-Toku first".
Set up the state you want to share
Get the participants, mode and display settings exactly how you want them shown. That whole state is what gets saved.
Press "Publish embed"
Grab the iframe snippet from the settings popup. Signing in is required for this step.
Paste it
Anywhere you can write HTML. WordPress: a Custom HTML block. Notion: type /embed and paste the URL.
| Destination | How | Works? |
|---|---|---|
| Blog / your own site | Paste the iframe snippet | Yes |
| WordPress | Custom HTML block | Yes |
| Notion | /embed then paste the URL | Yes |
| PowerPoint | Web Viewer add-in | Yes |
| Canva | — | No |
| Google Slides / Keynote | Paste the URL as a link and click it during the talk | No |
Note: What gets published is a snapshot of the settings at that moment. Changing the main app later will not change an embed you already pasted — publish a new one instead.
FAQ
Is participant data saved?
Yes, it's automatically saved to your browser's local storage. Opening in the same browser will restore your previous entries.
Can I use it on smartphones?
Yes, it works on smartphones and tablets. The sidebar is displayed at the bottom of the screen.
Are lottery results fair?
Every mode draws from a cryptographically secure random source (crypto.getRandomValues), so the result cannot be steered. Every participant has an equal chance. Background on how and why we built it: About Kime-Toku.
