(1, 50) Ruota dei numeri in omaggio
The entries are closed, the ticket numbers run 1 to 50, and fifty people are about to watch you pick one. SpinyWheel's (1–50) Giveaway Number Wheel puts the draw on screen at 2 percent per number, so the result arrives in front of everyone rather than from you.
How do you draw several winners without repeats?
Take each winning number off the board before spinning again. Left untouched, the wheel can hand you the same ticket twice, and a repeat in a prize draw is not a coincidence, it is two people holding one prize.
The risk climbs faster than most organizers expect:
| Winners needed | Chance of a repeat if nothing is removed |
|---|---|
| 2 | 2% |
| 3 | 5.9% |
| 5 | 18.6% |
| 10 | 61.8% |
Three winners is survivable odds. Ten winners drawn from an untouched fifty will collide more often than not, so a ten-prize draw run without removal is a coin flip on whether you finish clean. Pulling each winner out first makes distinct results certain rather than likely.
Match the wheel to the tickets you actually sold
A 1 to 50 wheel is right when 50 tickets went out. If 37 sold, spin 1 to 37, because a result nobody holds forces a re-spin, and a re-spin in front of an audience is the exact moment somebody asks how many times you plan to do that.
The same applies to gaps. Ticket books with missing or voided numbers need those numbers off the list before the draw starts, not handled by discretion afterward. Editing the entry list takes a moment and removes the only real opening for a fairness complaint. For draws keyed to people rather than tickets, the Selettore nome casuale takes the names directly.
Running a draw nobody disputes
State the rules before the first spin: how many winners, whether runners-up are drawn in the same session, and that results stand. Rules announced after a result look like a response to the result, even when they are not.
Draw the runners-up immediately while the wheel and the audience are both still there. Chasing an unclaimed prize a week later means reconvening people who have moved on, and a second draw always attracts more questions than the first. Blind Mode is useful when entrants can see the screen, since the labels stay hidden until the wheel stops and nobody can call the outcome early. Confetti, coins, and a fanfare mark the result clearly enough that everyone agrees on when it happened.
What visibility is actually worth
A hat, a spreadsheet, or a random number generator run off camera produce the same mathematics as a wheel and none of the credibility. Nobody watched the shuffle. Nobody saw the seed. The person announcing the result is also the person who produced it, and that is the structural problem a visible spin solves.
Screen sharing the draw on a call, or putting it on a projector at an event, moves the moment of selection out of your hands into everyone's view. If the prize is large enough that promotional rules or local regulations apply, check those before the draw rather than after, since no amount of transparency fixes a draw that was set up wrong. The Consigli covers running a wheel in front of an audience.
FAQ
Gira, annota il numero, rimuovilo dall'elenco dei partecipanti e gira di nuovo per tutti i vincitori di cui hai bisogno. La rimozione garantisce risultati distinti. Saltare questa opzione lascia una probabilità del 5,9% di un duplicato su tre estrazioni e del 61,8% su dieci, quindi la scorciatoia fallisce esattamente quando l'estrazione è più grande.
Taglia l'elenco al numero più alto effettivamente emesso prima di girare. Una ruota più ampia dell'intervallo del biglietto finirà per fermarsi su un numero che nessuno ha acquistato, forzando un nuovo giro che ti costa più credibilità di quella che la configurazione avrebbe richiesto. I numeri dei biglietti annullati o mancanti dovrebbero essere rimossi dall'elenco per lo stesso motivo.
Le probabilità sono le stesse e la differenza sta interamente in ciò che il pubblico può verificare. Un cappello nasconde lo strascico e la portata, quindi l'estrazione dipende dalla fiducia della persona che lo tiene. Un giro su uno schermo condiviso mostra l'elenco completo degli iscritti, il movimento e l'atterraggio, senza lasciare nulla che debba essere creduto.
Sì, e vale la pena farlo. Continua a girare dietro al vincitore principale, rimuovendo ogni risultato man mano che procedi e registra l'ordine. I premi non riscossi vengono quindi spostati in basso in un elenco che tutti hanno già visto, invece di richiedere una seconda estrazione che arriva senza la presenza del pubblico originale.
Close the entries, announce the rule, and spin once.
