Country Wheel — A Random Country Generator for Travel, Geography, and Curiosity
Can't decide where the next trip goes, or which corner of the map to teach today? Spin the wheel and let it drop you somewhere. Cryptographically random, works offline, no signup.
There are 195 countries on the map — pick one the fun way instead of arguing over it
为什么选择wheel.expert？
Break the 'Same Three Places' Rut
Most of us cycle through the same handful of destinations in our heads. The wheel doesn't have a comfort zone. Load fifty countries and it might land you on Georgia, Namibia, or Laos — somewhere you'd never have typed into a search bar on your own.
Settle the 'Where Should We Go' Standoff
Two people, four favorite countries, zero agreement. Put all of them on the wheel and let one spin end the deadlock. Nobody loses the argument because the algorithm made the call, not your travel partner.
Build Your Own List of Countries
Type a custom set — your bucket list, the nations in a continent you're studying, the visa-free spots from your passport. The wheel spins only what you load, so a 'just South America' wheel stays South American.
Spins in the Classroom, Offline
School WiFi cutting out mid-lesson? It still runs. Installed as a web app, the wheel works with no connection at all — on a projector, a tablet, or a phone passed around the dinner table.
Every Country, Equal Odds
Some random tools quietly favor whatever sits first in the list. This one pulls from the Web Crypto API — the randomness browsers trust for security keys — so tiny Tuvalu and enormous Canada have exactly the same chance of coming up.
Free, No Account
Nothing is paywalled, nothing is mailed to you, nothing is saved to a server. Open it, give it a spin, close the tab whenever you're done.
How to Use the Country Wheel
Load Your Countries
Start from the preset spread — USA, Japan, France, Brazil and the rest — or clear it and type your own. One country per slot: 'New Zealand,' 'Morocco,' 'Vietnam,' as many as you like.
Shape the List
Add countries, drop the ones that don't fit, reorder them however you want. A wheel of all 54 African nations plays very differently from a five-country shortlist, so match it to what you're actually deciding.
Spin
Tap the center. The wheel turns, slows, and stops on one country — picked by the algorithm, not by where you nudged it to land.
Go With It, or Spin Again
Take the result and start planning, researching, or cooking. Or pull the winner out and spin for the next one to build a whole itinerary. Earlier picks sit waiting in the history panel.
What People Actually Use the Country Wheel For
Picking the Next Trip
When the bucket list is too long to choose from, load it all and let one spin narrow it down. The randomness is the point — it surfaces the place you keep putting off rather than the easy default.
Geography Lessons and Map Drills
Teachers spin a country, then class finds it on the map, names the capital, and traces the borders. It turns rote memorization into a quick guessing game students actually lean into.
Cook-a-Country Dinner Nights
Spin a country and make a dish from it that evening — the cuisine, the spices, the table you'd never have planned. A standing weekly version slowly turns a kitchen into a passport.
Language and Culture Practice
Learners spin to choose where the day's practice 'visits' — read a short article from that country, learn three phrases, look up a tradition. Random targets keep the routine from going stale.
Trivia and Quiz Prep
Quiz hosts and students spin a country, then drill its flag, currency, and famous landmarks. It's a fast way to cover the whole map without always defaulting to the same big names.

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。

常见问题
Yes. Clear the presets and add any nations you want — 'Iceland,' 'Peru,' 'Bhutan,' one per slot. The wheel spins only what you load, so a wheel of just the countries you've never visited stays exactly that.
It's genuinely random. The picker draws from the Web Crypto API, the same source browsers use for security keys, so a small island nation has the same odds as a giant like Russia. There's no hidden weighting toward the top of the list.
Spin once, remove the winner, and spin again. Each country drops out of the next round, so a few spins hand you a route — first stop, second stop, third — with no repeats along the way.
It does. The country wheel installs as a progressive web app, so after the first visit it runs fully offline — useful in a classroom with shaky WiFi or on a flight while you sketch out an itinerary.
Plenty of teachers do. Project it, spin a country, and the class locates it, names its capital, and talks through what makes it distinct. It turns map review into a quick daily game rather than a worksheet — handy when you're covering all 195 countries over a term.
Easily. Load only the countries from that region — just the ASEAN nations, only the Nordics, or the full list of African states — and the wheel will never wander outside it. The pool is whatever you put in, nothing more.
