Quick Guide
Basic Setup
Enter prize names and winner counts, then click “Create Lottery”. You can use the form or paste text in bulk.
Drawing
Click “Start Lottery” to open the draw screen. Press “Draw” to pick one winner at a time.
Bulk Text Input
Use the “Text Input” tab to enter prizes in bulk. Format: “Prize name [space or comma] count” — one per line.
Manage Counts
During the lottery, tap “View Results” to check the current status. Use “Edit Counts” to manually adjust remaining numbers.
Sharing by URL
Opening a link made with “Copy URL” or with the X share button recreates the same prizes and settings. Each device still draws independently, so results and remaining counts are not shared or synced with anyone else.
Frequently Asked Questions
Q. How are the winning odds calculated?
The odds shown for each prize are its remaining count divided by the total remaining count. For example, with Prize A x1, Prize B x2 and Prize C x3 (6 in total), the first draw gives A 17%, B 33% and C 50%. Every draw removes one unit from the prize that was won, so the odds are recalculated automatically — this is a draw-without-replacement model. Tap “View Results” at any time during the lottery to see the current counts and odds.
Q. Can I run the whole lottery in a browser?
Yes. No installation and no sign-up are required — any modern browser such as Chrome, Safari or Edge will do. Everything runs locally on your device, so the prize names you type are never sent to a server. If you are presenting on a projector or a large monitor, use the “Fullscreen” button on the draw screen.
Q. Can I share the same lottery with other people?
Use “Copy URL” to generate a link with the prize names, winner counts, wait time, background and sound settings embedded in it. Opening that link recreates the same lottery instantly. Note that only the settings are shared: each device draws independently, and results and remaining counts are not synced. To run one lottery for a whole group, share the host’s screen in fullscreen mode instead.
Q. How many prizes can I register?
Up to 30. Add them one at a time with “Add a Prize”, or paste them in bulk from the “Text Input” tab using one line per prize in the format “Prize A 1”. Winner counts are set per prize and can still be adjusted mid-lottery with “Edit Counts”.
