SpinKit选择转盘：几秒做出免费旋转选择器
选项上转盘、一转定结果、少争吵——随机选择最友好的形态。
选择转盘名副其实：把选项放上旋转转盘，转一下，让指针选出一个。这是随机选择最友好的形态——不用丢骰子、不用争论硬币是否公平接住，只有大家看着停下来的转盘。
人们实际用选择转盘做什么
- 名字 — 课堂上谁下一个回答、谁赢赠品、谁轮到演示。
- 食物 — 外卖轮盘、晚餐轮换、和不肯选的朋友一起解决「去哪吃」。
- 奖品 — 抽奖与奖品抽取，转盘就是仪式本身。
- 游戏 — 真心话大冒险、惩罚转盘、直播与派对的挑战选择器。
- 工作 — 站会顺序、代码评审分配、谁主持复盘。
- 决策 — 任何你已绕了十分钟的小选择；见 决策转盘指南。
大约三十秒做出一个
- 打开 SpinKit 选择转盘 — 无需账户。
- 粘贴或输入选项，每行一个。
- 旋转 — 用手指轻扫或点中心。
转盘会自动保存在你的设备上，可离线使用，你也可以保留任意数量的独立转盘——一个管晚餐、一个管班级点名、一个管惩罚名单。
值得了解的设置
- 加权扇区。给条目更大扇区，它就按比例获得更好概率——人人可见，因此仍公平。适合一次买多张的抽奖票。
- 旋转后移除赢家。已抽条目离开转盘，避免同一人被选两次——正是把选择转盘变成正式 抽奖 的设置。
- 抽奖模式。在一次会话中抽取多名赢家，而无需手动反复旋转。
- 颜色与主题。色板、逐条颜色与深色模式，让转盘在投影仪或直播叠加层上看起来合适。
分享这次旋转
选择转盘是群体工具，因此 SpinKit 为展示而设计：一键全屏适合课堂与投影仪，短链接可与任何人分享转盘，嵌入可将实时转盘放进你自己的网站，而实时房间让远程群体在同一时刻观看同一次旋转——带聊天，甚至可移交控制权。
转盘不适合当选择器的时候
转盘一次只选一件事。若需要随机组合（一道前菜 + 一道主菜 + 一道甜点），请用 老虎机卷轴。若要从电子表格中抽取随机行，请用 Spin Sheet。若要把名单分成公平小组，分组生成器 一键完成。同一应用、同一名单——只是换对了随机的「形状」。
One wheel per job, not one mega-wheel
A picker wheel earns trust by being obviously about one decision. The class-register wheel should not also hold Friday’s forfeit list. The dinner wheel should not still contain last month’s raffle prizes. Mix jobs on one wheel and you will eventually spin a name when you meant a takeaway, or a prize when you meant a chore. Save separate wheels. Name them after the job, not after the tool.
The same rule applies to leftovers. After a raffle, do not leave the winner on the wheel “as a souvenir” if you might spin that wheel again tomorrow. Remove, reset, or duplicate into an archive copy. A picker that still contains last week’s winner is how someone gets drawn for a prize they already won — or, worse, how a leftover dummy slice steals a chance from a real entry.
When a picker wheel is the wrong ceremony
Use a picker wheel when the room needs to watch one option land. Skip it when the job is a documented draw from a spreadsheet, a without-replacement sample of two hundred rows, or a team split that must stay even. Those jobs have tools that keep the extra columns, the export, or the group sizes attached. Pasting two hundred emails onto a wheel so the slices are unreadable is not “more festive”; it is harder to check.
If someone may ask “prove that was the list”, keep a receipt and show the entries before you spin. A picker wheel without a visible list is just a coin you flipped in another room. Local-first helps here: the list lives on the device you are presenting from. You do not need an account to start, and you should not need a login wall to finish a classroom pick.
Without-replacement is a setting, not a vibe
“Don’t pick the same person twice” is a rule you turn on, not a hope. If remove-winner is off, repeats are fair. If it is on, the pool shrinks and late names get a larger share of what is left — which is also fair, and worth saying out loud so nobody thinks the wheel “got stuck” on the last few slices. Decide the rule before the first spin. Changing it halfway through a raffle is how a room stops believing you.
Raffle mode — several winners from one session — is the same idea with less clicking. Draw the main winner, then the reserves, from one list, in view. Do not spin once, screenshot, then quietly spin again off-camera for a “backup”. The backup is part of the ceremony or it is not a backup.
