Sports Wheel — A Random Picker for Which Sport or Workout to Do Today
Can't decide what to play or how to train? Type in your sports, your drills, or the gear you've got, then spin. The wheel hands you one — and the deciding is done. Cryptographically random, works offline, no signup.
From the PE gym to the driveway hoop — a faster way past 'I don't know, what do you want to do?'
为什么选择wheel.expert？
Beat the Same-Workout Rut
You know the trap: you walk into the gym and default to the treadmill again. Load a list of everything you'd actually do — rowing, kettlebells, a swim, a long ride — and let the wheel assign today's session. Variety, decided for you.
Spins in the Gym With No Signal
Locker rooms and field houses eat WiFi. This installs as a web app and runs with zero connection, so a coach on a back field or a kid in the basement can still spin for the next drill.
Load the Sports You Can Actually Play
No point spinning 'surfing' if you're landlocked. Wipe the presets and type only what fits your space and gear — half-court, a jump rope, a park, two cones. The wheel spins your real options, nothing else.
End the Pickup-Game Standoff on the Spot
Six friends at the park, six opinions on what to play. It loads fast and works by touch, so 'basketball or ultimate?' gets settled before anyone loses interest and drifts home.
Every Sport, Equal Odds
Some random pickers quietly lean. This one draws from the Web Crypto API — the same randomness browsers use for security — so the sport nobody volunteers for has exactly the same shot as everyone's favorite.
Free, No Account
Nothing's paywalled, nothing's emailed, nothing's stored. Open it on the sideline, spin it, get moving.
How to Use the Sports Wheel
List Your Sports or Exercises
Start from the preset spread of soccer, basketball, swimming and the rest, or clear it and type your own. 'Tennis,' 'burpees,' '5K run,' 'rock climbing' — anything you'd put your body through goes on.
Tune It to the Day
Add as many activities as you want, rename them, drop the ones that don't fit. A wheel of indoor bodyweight moves looks nothing like a wheel of team sports — match it to where you are and who's there.
Spin
Tap the center. The wheel turns, slows, and lands on one sport — picked by the algorithm, not by whoever's loudest in the group.
Go Play, or Build a Circuit
Take the result and start moving. Or remove it and spin again to stack a multi-station workout — sprint, then jump rope, then planks. Past picks stay in the history panel.
What People Actually Use the Sports Wheel For
PE Class 'Which Sport Today'
Instead of running the same unit on a loop, teachers load a term's worth of activities and spin the day's focus on the projector. Kids buy in more when the wheel calls it, not the adult.
Killing Gym Boredom
Doing the same routine until you quit is the oldest fitness failure there is. Spin a random session to break the pattern, and you train muscles your defaults always skip.
Kids' Active-Play Rotation
Antsy kids, a backyard, no plan. Load tag, hopscotch, jump rope, an obstacle course and a soccer kickabout, and spin the next ten-minute burst whenever the energy dips.
Trying a New Sport
Stuck in a one-sport groove? Load a shortlist of things you've never tried — pickleball, bouldering, kayaking, table tennis — and let the wheel commit you to one this month.
Cross-Training Randomizer
Athletes who train one discipline need variety to stay healthy. Spin a complementary activity on off days so recovery work stops feeling like a chore you keep postponing.

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 type whatever you'd actually do — 'pickleball,' 'kettlebell swings,' 'beach volleyball,' '400m repeats.' The wheel only spins the activities you load, so a landlocked list never lands you on surfing.
It is. The picker pulls from the Web Crypto API, the same randomness source browsers use for security keys, so the drill nobody likes has the same odds as the crowd favorite. No hidden weighting toward the easy stuff.
Spin once, hit 'remove winner,' and spin again. Each pick drops out of the next round, so four or five spins give you a no-repeat circuit — say, sprints, then planks, then jump rope, then a cooldown stretch.
It does. The sports wheel installs as a progressive web app, so once it's loaded it runs offline — useful on a back field, in a gym with dead WiFi, or at a park with no signal at all.
Plenty do. Load the term's activities, put it on the projector, and spin the day's sport in front of the class. Letting the wheel decide cuts the 'why not soccer again' arguments and gets everyone moving sooner.
Then load just those. A two- or three-option wheel works fine, and the slow wind-down still makes the result feel like a real call — better than a coin flip when it's tennis, a run, or a rest you're torn between.
