About Stad10

Stad10 is a small, independent site of free sports tools. Each page does one job well: keep score at the dartboard, work out a bowling handicap, draw a volleyball rotation, plan a round-robin league or run a sports quiz at the pub.

Everything runs in your browser. We do not ask you to sign up, and the numbers and names you type stay on your device (some tools save your last game in your browser's local storage so a refresh does not wipe it).

We write the formulas, rules and dimensions from the official rule books of each sport and test every calculator against worked examples before it goes live. If you spot a mistake, please tell us and we will fix it.
