Typing Speed Test

Random Name Picker

Dice · Coin · Random

These are the little tools you need ten times a year and never have installed: a spinning wheel for picking names in class or giveaways, a fair team splitter, dice from d4 to d20 for board game night, coin flips and no-duplicate lottery draws. Everything is uniformly random and runs offline once the page loads.

The typing test measures words per minute and accuracy on real sentences, not random letters — the number you get is the one that matters for actual writing and coding. Try it monthly and watch the trend.

Frequently asked questions

Is the wheel really fair?
Yes — the winner is chosen with a uniform random number, and the spin animation just plays toward that result. Every name has exactly the same chance.
What is a good typing speed?
Average is around 40 WPM. 60+ is comfortably fast for work, 80+ is fast, and 100+ puts you in the top few percent.
How does the team splitter keep teams fair?
It shuffles the full list randomly, then deals names round-robin like cards — team sizes never differ by more than one person.
Are the dice rolls and coin flips truly random?
Yes — they draw from the same uniform random source as the wheel, so every face and every side is equally likely, and each roll is independent of the last. There is no streak correction: five heads in a row really can happen, exactly like with a physical coin.
Can I use these tools in a classroom?
They are made for it. Teachers use the wheel to call on students fairly, the team splitter to form groups for projects in seconds, and the dice for math games — all without accounts, installs or student data. Project the page on the board and the whole class can watch the draw happen.
Do the tools work offline?
Once a page has loaded, all the randomness runs on your device — you can spin the wheel, roll dice or split teams with no connection at all. That makes them reliable in classrooms, gyms and event venues where the Wi-Fi is shaky.
