How to Run a Free Twitch Giveaway with a Spin Wheel in OBS

There are plenty of ways to pick a giveaway winner — a random-number generator off-stream, a bot that whispers you a name, a hat full of paper. They all share one problem: your audience has to take your word for it. A spin wheel fixes that. The entries are visible, the spin is visible, and the result lands in front of everyone in real time. Nobody can claim the draw was rigged when they watched the pointer stop.

One disclosure up front: we make Wheel of Item, so we list it first. We've still tried to be fair about the alternatives — there are other free OBS wheels, and we'll point out what to look for so you can judge for yourself. Anything we say about a competitor is "at the time of writing"; verify current features on their own site before relying on them.

Why a wheel is the fairest way to pick a winner live

Fairness on stream isn't just about the math being random — it's about the audience being able to see that it's random. A spin wheel wins on both counts:

• Every entry is on screen. Each name is a slice, so the full pool of who could win is visible before the spin. No hidden list, no "trust me, they were in there."
• The draw happens in public. One spin, watched by the whole chat at once. There's no off-screen step where the result could be swapped.
• The result is unambiguous. The pointer stops on exactly one slice. There's no rounding, no "the bot picked seat 14" that nobody can verify.
• Equal slices, equal odds. When every entrant gets one slice of the same size, the probability is obviously even — viewers can see the wheel is balanced rather than having to trust a black box.

That visibility is the whole point. A wheel turns "I promise it was random" into "you all just saw it happen." For a giveaway, that trust is the prize-presentation.

Step 1 — Collect the entries

You have two clean ways to fill the wheel, and you can mix them.

Chat command (hands-off). With Wheel of Item's streamer tools connected to your Twitch chat, viewers type a command like !add to put their own name on the wheel. This is the most transparent option: chat sees each entry arrive, and you never touch the keyboard. You can gate it to followers, subs, or everyone, and set whether mods can run !add on someone's behalf. Pair it with !list so anyone can check who's currently in, and !remove to pull an entry if needed.

Paste a list (manual). If your entries come from somewhere else — a Discord thread, a sign-up form, last stream's no-shows — just paste the names into the wheel, one per line. The wheel rebuilds the slices instantly. This is handy when the giveaway pool was decided before you went live.

Either way, decide your entry rule out loud before you start (for example, "one entry per person, must be following"). Stating the rule on stream is part of what makes the result feel fair — and it sets up the de-duplication step we cover in the FAQ.

Step 2 — Add the wheel as an OBS browser source

Because the wheel is a web page, getting it on stream is just a browser source — no plugin, no install, no green screen.

1. Open the wheel and copy its overlay URL from the streamer tools (the widget link built for OBS).
2. In OBS Studio, click + under Sources and choose Browser.
3. Paste the URL. Set the width and height to match the size you want on your canvas (a square like 800×800 keeps the wheel crisp).
4. Leave the background transparent — the widget renders on a clear canvas, so the wheel floats over your scene with no box around it. There's nothing to chroma-key.
5. Position and scale it, then lock the source so you don't nudge it mid-stream.

The same browser source works in Streamlabs Desktop and other OBS-based tools the same way. Once it's placed, it stays put — you only spin it; you don't have to re-add it each stream. If you want the full walkthrough with screenshots, see our guide on adding a spin wheel to Twitch and OBS.

Step 3 — Spin it live

This is the part your audience came for, so make it a moment. Read out the entry list (or let !list do it), confirm the prize, then spin.

You can trigger the spin three ways:

• Manually — click or use a chat command like !spin when you're ready. Simple and controllable.
• On a donation — connect Streamlabs, StreamElements, or Ko-fi so a tip auto-spins the wheel. This turns a giveaway into a fundraiser: the donation both enters the moment and pulls the lever, and the winning name can be read aloud with text-to-speech. Most free OBS wheels can't do this — it's where Wheel of Item pulls ahead.
• On a milestone — spin when you hit a follower or sub goal, so the whole channel is invested in the same result.

Whichever you pick, the key is that the spin happens where chat can see it. Don't cut away, don't pre-record it — the credibility comes from the live, single, public spin.

Step 4 — Announce the winner

When the pointer stops, say the name out loud and drop it in chat so it's on the record. A few habits keep the close as clean as the draw:

• Show the result, don't summarize it. Let the wheel sit on the winning slice for a beat before you talk over it — viewers want to confirm what they just saw.
• Have a claim plan. Tell the winner how to claim (DM, a form, "stick around after stream") so the moment doesn't fizzle.
• Decide re-spin rules in advance. If the winner is absent, say up front whether you re-spin immediately or hold the prize. Improvising this is where "rigged" accusations sneak in.

Then reset the wheel for the next round. If you used chat entries, clearing the list and reopening !add starts a fresh, equally fair draw.

An honest look at free OBS wheels

We're not the only free wheel you can put in OBS, and the right pick depends on what you need. Rather than trash anyone, here's what actually matters when you compare them — and where each tends to land.

How the field shakes out. FateWheel is a strong, genuinely free option and often ranks first for "wheel spinner for OBS" — it gives you a free chroma-key browser source and does the core job well. What it doesn't do is react to your audience: there's no donation auto-trigger, and it stays a pure spinner (no gachapon or text-to-speech). Tools like WheelOrbit and SpinStream cover the manual or command-triggered spin nicely but, again, are about spinning on demand rather than reacting to a tip. Wheel of Item's edge is the reactive layer: it's the same free transparent overlay, plus chat entries, plus the donation auto-spin and TTS that the others leave out. If all you ever need is a manual spinner, any of these will serve you; if you want the wheel to respond to donations and chat, that's the gap to weigh.

Bottom line: pick on the four rows above, not on the logo. If a free wheel checks transparent overlay, chat entries, and a donation trigger, you're in good shape — and that combination is exactly what we built Wheel of Item around.
