Every creator who has run a giveaway has seen the comment: rigged. Usually it is a joke. Sometimes it is not, and once that doubt takes hold it is very hard to shift. The frustrating part is that the randomness is almost never the problem — the process around it is.
Publish the rules before entries open
Say what the prize is, who can enter, when entries close, how a winner will be chosen and when they will be announced. Rules written after entries have arrived always look like rules written to fit a result, even when they are not.
Make entry counting boring and obvious
If sharing earns extra entries, say exactly how many and how you will verify them. Vague bonus systems are where most accusations start, because nobody outside your head can check the arithmetic. Weighted entries help here: rather than pasting a name repeatedly, write it once with its multiplier so the wheel shows a wider slice. The advantage becomes visible instead of hidden.
Draw where people can see it
A live draw on stream, a screen recording, or even a photo of the finished wheel gives your audience something concrete. The point is not that a video is impossible to fake — it is that a public, timestamped process raises the effort of cheating far above the value of the prize, and everyone knows it.
Keep the entrant list
Export or screenshot the list you actually spun. If someone asks whether their entry counted, being able to show them their name on the wheel ends the conversation in one message.
Announce properly, and have a backup rule
Name the winner publicly and say how they will be contacted. Decide in advance what happens if they do not respond — a stated window, then a redraw, is standard and nobody objects to it if it was in the rules from the start.
Know the law where your entrants live
Prize promotions are regulated, and the rules differ considerably between countries. Requiring a purchase to enter, for example, turns a giveaway into something quite different in many places. This article is not legal advice; if your promotion is large or crosses borders, get advice that is.
None of this is difficult. It is mostly a matter of deciding things before you need them, and then showing your working.
