🎓

Nobody Can Cry Favoritism

When the wheel calls a name, there's no arguing the teacher 'always picks the same kids.' The choice happens in plain sight, on the projector, and it's out of your hands — which is exactly why students accept it.

🙋

Pulls In the Quiet Ones

Shy students often coast because the same three hands go up every time. Random selection quietly changes the math: everyone knows their name is in the wheel, so they stay ready instead of hiding in the back row.

🔌

Spins With the WiFi Down

School networks drop at the worst moments. Install the wheel once and it keeps running with no connection — handy in a gym, a field-trip bus, or that one classroom where the signal never reaches.

🗑️

Remove a Name So Everyone Gets a Turn

Tap 'remove winner' after a spin and that name drops out of the next round. Work down the list and every single person gets called once before anyone gets called twice — no spreadsheet, no tally marks.

⚖️

A Genuinely Even Draw

Some pickers quietly favor whatever name you typed first. This one draws from the Web Crypto API — the same randomness source browsers use for security keys — so the last name on the list has the exact same odds as the first.

🆓

Free, No Account, Nothing Stored

No signup screen, no email capture, no ads parked over the spin button. The names you add stay in your browser and vanish when you close the tab.

How to Pick a Name Fairly

1

Drop In the Names

Type names one per line, or paste a whole class roster, sign-up sheet, or attendee list at once. The wheel slices itself evenly the moment the names land — eight names or eighty.

2

Set the Mood

Pick colors, a celebratory sound, a spin speed. A slow wind-down builds suspense for a raffle draw; a quick snap suits rapid-fire cold-calling between questions.

3

Spin and Let It Land

Tap the center and step back. The wheel turns, slows, and stops on one name — chosen by the algorithm, not by where you nudged it. Read the name aloud and you're moving.

4

Keep It or Clear It

Calling on people one at a time? Hit 'remove winner' and spin again for the next turn. Running a draw where someone could win twice? Leave every name in and spin fresh each round.

Where a Fair Name Draw Actually Helps

🍿

Cold-Calling Without the Dread

Equity sticks — names on popsicle sticks pulled from a cup — are a long-standing teaching method for spreading questions evenly. The wheel is the same idea, just bigger on a screen and impossible to fudge.

예시: A teacher projects the wheel and spins after each question, so the answer never lands on the usual two hands
🎟️

Raffle and Door-Prize Draws

Load every entrant's name, spin for the prize, then remove that name and spin for the next one down. The crowd watches the same wheel you do, so there's nothing to dispute when their name doesn't come up.

예시: A PTA fundraiser draws first, second and third prize on stage — remove winner between each spin
🗣️

Who Presents First

Deciding speaker order by hand always feels rigged to whoever goes last. Spin once per slot — or remove each name as it's called — and the running order comes out of thin air instead of out of seniority.

예시: A standup sets its update order by spinning the team's names, so nobody games the rotation
🧹

Picking Who's On the Hook

Line leader, snack helper, the one who has to summarize the reading — someone has to do it. A spin assigns the unglamorous jobs without the groan of 'why me again,' because the wheel doesn't hold grudges.

예시: Classroom jobs get handed out by a Monday spin, and the loudest complainer can't blame the teacher
🎲

Whose Turn Goes Next

Board game night, a trivia round, a kid arguing they 'never' go first — spin the names and the order is settled before the squabble starts. Turn after turn, remove the last name so the whole group cycles through.

예시: Three siblings stop fighting over who goes first once a phone wheel decides it for them

진정한 무작위 선택 - 알고리즘 작동 방식

많은 휠 스피너가 Math.random()을 사용하는 것과 달리, wheel.expert는 암호학적으로 안전한 난수 생성을 위해 Web Crypto API(crypto.getRandomValues())를 사용합니다. 이는 비밀번호 생성기와 같은 보안 중요 애플리케이션에서 사용하는 것과 동일한 API입니다.

🔐

웹 암호화 API(CSPRNG)

모든 최신 브라우저에 내장된 암호학적으로 안전한 의사 난수 생성기(CSPRNG)인 crypto.getRandomValues()를 사용합니다.

⚖️

편향 없는 선택 알고리즘

모든 항목의 가중치가 같으면 거부 샘플링을 사용하여 무작위 선택에서 흔히 발생하는 문제인 모듈 편향을 제거합니다. 이렇게 하면 각 항목이 선택될 확률이 수학적으로 동일하게 됩니다. 가중치 항목의 경우 확률은 할당된 가중치에 비례합니다.

🛡️

클라이언트 측 투명성

모든 무작위 선택은 회전 시 브라우저에서 이루어집니다. 코드는 열려 있으며 브라우저의 DevTools를 통해 검사할 수 있습니다. 대규모 경품의 경우 시청자에게 공정성을 입증하기 위해 스핀 중 화면 녹화를 권장합니다.

🔍 직접 확인: DevTools(F12)를 열고 콘솔에서 난수 생성을 확인하세요. 우리는 은행 및 보안 애플리케이션에서 사용하는 것과 동일한 암호화 API인 window.crypto.getRandomValues()를 사용합니다.
