A picture of a winner's name is not evidence of anything. A recording of the draw is better, because it shows the entrant count and the spin as well as the outcome.
What a Spinnza recording contains
The video is the real wheel on the page, framed for posting and carrying the facts of the draw around it the whole way through — not on a title card at the start that a clip could be cut away from:
- The draw title across the top, and under it the entry count, the total chances if weights are on, and a running tally of how many have been drawn so far
- Every spin of the session, at the speed you set, with each winner landing on screen
- The Entry List ID along the bottom — the SHA-256 fingerprint of the exact entries and weights you drew from
- The date and time, if you left the timestamp on
Because the count and the fingerprint sit in the frame on every frame, a screenshot taken from anywhere in the video still carries them, and a clip cut out of the middle cannot lose them.
How to run one
- Get your final list on the wheel and set everything the way you want it — names, winner count, colours, speed. Buy a recording credit if you do not have one.
- Press Start recording. From that moment the list and the settings are locked, so the Entry List ID cannot change mid-draw.
- Spin. The recording follows the real wheel on the page, so you control the pace and you can draw as many times as the session needs.
- Press Done recording when the draw is over. The video is made in your browser and downloads from there.
Nothing about it is on a timer and nothing spins by itself. It records the draw you run, on the page you were already using, which is why you can talk over it, read the names out, or stop and start the spins as slowly as you like.
Real-time pauses
There is one choice to make before you start: whether to include real-time pauses.
- Unchecked, the video cuts from spin to spin. Everything between the spins — reading names out, finding the next prize, somebody talking to you — is left out, and you get a tight clip of the draws themselves.
- Checked, the video runs the whole session, gaps and all. Use this when the pauses are the content: a live audience, commentary, or a draw where the waiting is the point.
Unchecked is the default because most people want the draws rather than the thinking time, and a four-minute video of somebody deciding what to do next is not proof of anything extra.
Formats
Vertical is 1080 × 1920 for Reels, TikTok and Shorts, square is 1080 × 1080 for feed posts, landscape is 1920 × 1080 for YouTube and desktop. Pick the format before you start recording — it sets the shape of the frame, so it cannot be changed once the session is running. The file is MP4 where your browser can encode it, otherwise WebM.
Most of this gets watched with the sound off, so the frame carries the count, the title and the timestamp as text rather than relying on you saying them.
The receipt
The video downloads with a receipt for the same draw in three forms, and they are for different jobs. The PDF is the one to attach to an email or hand to somebody who asked for paper. The text one is for copying a line out of into a post. The JSON one is for anybody who wants to check the entry list fingerprint themselves.
All three carry the same facts: the title, the entry count, the total chances if weights were on, the Entry List ID, the winners in order, the time and the time zone.
What it does not do
It is not legal certification, notarization or an independent audit, and the timestamp is your device's clock rather than a trusted timestamping service. It is a clear, dated record of a draw you ran — which is what almost every argument actually needs.
It also cannot prove the list was the right list. Nothing can: only you know what you collected. What the fingerprint does is tie the draw to one exact list, so that if you published the entries — or even just the ID — beforehand, the two can be checked against each other afterwards. Post the ID when entries close and the recording becomes much harder to argue with.
