为什么选择wheel.expert？
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
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.
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.
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.
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.
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.
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.
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.
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.

真正随机选择 - 我们的算法如何工作
与许多使用Math.random()的转盘不同，wheel.expert使用Web Crypto API（crypto.getRandomValues()）进行加密安全的随机数生成。这与密码生成器等安全关键应用程序使用的API相同。
网络加密 API (CSPRNG)
我们使用crypto.getRandomValues()，这是所有现代浏览器内置的加密安全伪随机数生成器（CSPRNG）。
无偏选择算法
当所有条目具有相同的权重时，我们使用拒绝抽样来消除模块偏差 - 随机选择中的常见问题。这确保了每个条目都有数学上相同被选中的机会。对于加权条目，概率与指定的权重成正比。
客户端透明性
所有随机选择均在旋转时在您的浏览器中发生。该代码是开放的，可以通过浏览器的开发工具进行检查。对于大额赠品，我们建议旋转过程中进行屏幕录制，以证明对观众的公平性。
🔍 亲自验证： 打开 DevTools (F12) 并在控制台中检查我们的随机数生成。我们使用 window.crypto.getRandomValues() - 与银行和安全应用程序使用的加密 API 相同。
