What is the Coin Flip, Dice Roller & Random Picker?
Settle a decision, run a tabletop game or pick a winner with results that are genuinely fair. The coin flip animates a real coin and tracks heads and tails, the current streak and the running percentage; flip one coin or up to 100 at once. The dice roller handles any number of dice from one to ten with 4, 6, 8, 10, 12, 20 or 100 sides, adds a modifier such as +3 for tabletop role-playing games, and keeps a history of recent rolls.
For everyday choices there is a big Yes/No button and a list picker: type one option per line, press Pick, and optionally avoid repeats until every item has been chosen. All randomness comes from your device's cryptographic random generator with rejection sampling, which removes modulo bias, so every outcome is exactly equally likely. Nothing is stored or sent anywhere.

Questions people ask
Is it truly random?
It uses the browser's cryptographic random number generator (crypto.getRandomValues) with rejection sampling, so all outcomes are equally likely.
Can I flip many coins at once?
Yes — 1, 2, 3, 5, 10 or 100. The result shows the number of heads and tails.
How do I roll a d20 with a modifier?
Choose 1 die, 20 sides and set the modifier, for example +5.
Does the list picker remember items?
No. Nothing is stored; it works entirely in your browser.
Why did I get five heads in a row?
Streaks are normal in random sequences; every flip is independent of the last.
