Kime-Toku
What is KimeToku?
KimeToku is a free lottery app for streamers. It features 7 lottery modes including Roulette, Slot, Shuffle Cards, Lottery, Ranking announcements, Team Division, and Coin & Dice. With OBS transparency support, you can overlay it directly on your stream.
Five minutes of setup, and you never have to switch scenes mid-giveaway again.
Open Kime-Toku and copy the URL →OBS Setup Instructions
Add Browser Source in OBS
Open OBS Studio and click the '+' button at the bottom of the Sources panel. Select 'Browser' from the menu and give it a recognizable name (e.g., "Roulette").
Set KimeToku URL
In the properties window, configure the following settings:
- URL:
https://kime-toku.com - Width:
1280 - Height:
720
Enable Transparency (Important)
In the same properties window, make these changes:
- Delete all content in the "Custom CSS" field (leave it empty)
- Check the "Enable transparency" option
This makes the background transparent, showing only the roulette on your stream.
| Field | Value | Why this value |
|---|---|---|
| URL | https://kime-toku.comIf a white strip shows at the bottom: https://kime-toku.com/?peek=0 | Loads the lottery screen as-is. OBS hides the white strip (the participant input) automatically; add ?peek=0 if it still shows in Streamlabs, XSplit, vMix and the like |
| Width / Height | 1280 / 720 | Match your canvas. Too small and the wheel gets squashed |
| Custom CSS | empty | The default snippet sets a background color, which cancels transparency |
| Enable transparency | ✓ ON | Leave it off and the white background goes on stream. This single checkbox decides it |
| Shutdown source when not visible | OFF | If ON, the page reloads every time you switch scenes, so the result on screen and any running animation disappear (your participant list is stored in the browser and survives) |
Control KimeToku and Start
To interact with KimeToku while streaming, right-click the browser source and select "Interact". This allows you to control the interface directly.
- Enter participant names in the "Participants" field at the bottom of the screen (one per line)
- Pick a lottery mode from the mode selector at the top right (Roulette, Slot, etc.)
- Click the "Start" button
Tip: Click "Stream Window" to open the lottery display in a separate window. You can then capture this window using OBS "Window Capture". This is useful when you want to separate the control panel from the display.
Using Green Screen Mode
If the transparency setting doesn't work or you prefer using chroma key compositing with other software, you can use green screen mode.
- In KimeToku, click the palette button (🎨) at the bottom left and turn on "Green screen" in the "Settings" tab
- In OBS, add a "Chroma Key" filter
- Select "Green" as the key color type
Note: Green screen mode may result in lower quality compared to the transparency setting. We recommend using the "Enable transparency" option whenever possible.
Common Issues and Solutions
Background Not Transparent
If the default CSS remains in the "Custom CSS" field, transparency won't work. Delete all content from this field. Also verify that "Enable transparency" is checked.
Roulette Not Displaying
Check that the URL is entered correctly. You need the complete URL including https:// (https://kime-toku.com).
Cannot Control the Interface
Right-click the browser source and select "Interact" to enable control. To exit interact mode, press Esc or click elsewhere.
