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?'
wheel.expert를 선택하는 이유
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.

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.

자주 묻는 질문
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.
