Privacy
This tool runs entirely in your browser. Names, results and history are never sent to a server and stay on your device. The one exception is Share: creating a short link / QR code stores that Amidakuji on share.omikuji.dev (deleted automatically one year after its last access).
FAQ
How many players can I add?
From 2 up to 200 players. Works on both desktop and mobile.
Are the results fair?
Amidakuji is mathematically fair — once the lines are set, each starting column maps to exactly one outcome. The horizontal lines are placed randomly from a seed.
Can I save a ladder I'm working on?
Copy the URL to share a fully-configured ladder, and every ladder you generate is saved to your history automatically.
Is my data sent anywhere?
Not normally. Everything is processed and stored locally in your browser. Only when you create a short link or QR code via Share is that Amidakuji stored on share.omikuji.dev (deleted automatically one year after its last access).
