Everyone who uses a random picker eventually asks the same question:is it actually random? Fair question. This page is a plain walkthrough of what “random” means on Spin The Wheel, why the same name winning twice in a row is not a bug, and how weighted entries change the odds.

What the wheel is doing when you press Spin

Under the hood, a spin is not a physics simulation of a spinning disc. The animation you see is a display. The winner is decided by asking your browser’s built-in random source for a number, then mapping that number to a slice of the wheel proportional to each entry’s weight. The wheel then animates to a position that shows that slice under the pointer.

Nothing about your previous spins, your name, the time of day, or the order you added entries affects the number the browser hands back. Each spin gets its own fresh random draw.

Fair, in one sentence

On a wheel where every entry has the same weight, every entry has the same chance of winning on every spin.

Add a second entry, they each have half the chance. Add a tenth, they each have a tenth. That’s it — that’s the “fair” part.

Independent spins — the part people find weird

Every spin is independent of the ones before it. If you have ten equally-weighted names and Alex wins three times in a row, Alex is not “due” to lose the fourth. Nor is anyone else “due” to win. On the next spin, Alex has the same chance as everybody else — the same chance they had on the first spin.

This is called the gambler’s fallacy: the intuition that past outcomes shift future odds so things “even out”. In a truly independent process, they don’t. Long streaks are unusual but not impossible, and they don’t break the fairness of the wheel.

Why streaks happen more often than you think

Flip a coin twenty times. Getting five heads in a row somewhere in that sequence is more likely than most people guess — around a fifty-fifty chance. Streaks in a fair process are the norm, not evidence of tampering. If you run twenty spins on a ten-name wheel, seeing a two-in-a-row repeat somewhere in the sequence is almost expected.

A wheel that never repeated would actually be the suspicious one — that would take active intervention.

Weighted entries

Every entry has a weight (the default is 1). You can raise or lower it from the entry editor. Higher weights make a slice proportionally bigger on the wheel and proportionally more likely to be picked.

Two entries with weight 1 and 1 = each wins about half the time.
Two entries with weight 3 and 1 = the first wins about three times more often than the second.
Setting a weight to 0 removes an entry from the draw without deleting it.

Weights are a way to bias the odds when you want to. On an equal-weight wheel, weights aren’t doing anything and every entry is interchangeable from the RNG’s point of view.

Two spin toggles that change what “random” looks like

Remove Winner

When Remove Winner is on, the winning entry is deleted from the pool immediately after each spin. This makes the wheel behave like a raffle or a draft: each result is unique until the wheel is empty. Odds change spin to spin, because the pool shrinks each time.

Shuffle on Spin

Shuffle on Spin randomises the order of the entries at the start of every spin. It doesn’t change the odds — the random draw is independent of the order — but it stops the visual pattern of the same slice always sitting in the same place.

Common misconceptions

“The wheel is rigged to pick short names.”

It isn’t. Slice sizes are set by weight, not by label length. A long name and a short name both with weight 1 have identical odds. The visual slice widths are the same; only the label text renders differently.

“The wheel remembers what won last time.”

It doesn’t. Each spin draws a fresh random number and knows nothing about the last one. The site does show you a spin history soyou can review recent winners — that’s a UI feature, not an input into the next spin.

“If I refresh, I’ll get a different winner for the same wheel.”

Yes — and that’s correct. Refreshing doesn’t “save” anything from your last visit; each fresh spin is a new independent draw. If a decision needs to feel binding, run one spin and stick with the result.

“Spinning faster or slower changes the odds.”

No. The spin duration setting only affects the animation. The random draw happens the same way whether the wheel spins for three seconds or ten.

When a random pick is a good tool

Classroom cold-calling that feels fairer than picking with your eyes.
Deciding what to cook, watch, or read when everyone’s indecisive.
Team standups: who goes first.
Prize draws for small giveaways, where the entries are already known and finite.
Ice-breakers and party games.

When it isn’t

A random pick is not a substitute for judgement on decisions with real consequences — health, money, legal exposure, safety. Read the disclaimer for the full framing.
